Treat Winter Blues Naturally
Scientific research has shown that the natural rhythms of our bodies are regulated by light. Our exposure to sunlight in the winter, especially in more northern areas, is significantly reduced. For some individuals, this reduction in sunlight exposure can result in a mood disorder commonly known as the "winter blues," which can result in reduced energy, low moods, and disrupted sleep patterns.

Research has shown that light therapy use, even for as little as 15 minutes a day, can significantly reduce these symptoms by providing your body with the required amount of light exposure otherwise lacking during the darker months of the year. The goLITE BLU effectively mimics the natural patterns and spectrum of sunlight that our bodies need most. And best of all, the goLITE BLU provides a natural and affordable method of treating winter blues without using artificial stimulants or drugs.

Cutting-Edge BlueWave Technology
With 20 years of experience in light box technology, Philips offers the most cutting-edge and effective technology for treating winter blues with BlueWave technology. With this technology, the goLITE BLU provides blue light, which has been shown to be twice as effective as white light in influencing our natural body clocks. With BlueWave technology, the goLITE BLU is not only more effective than white-light light boxes, but it also offers far less intense light, which reduces the risk of eyestrain or headaches that can be associated with the glare of more intense light boxes.

The goLITE BLU also features a wider field of light than other light boxes, which means that you can work, watch TV, read, or eat meals while using the light box, rather than having to sit close and directly in front of it.

Easy to Use, Compact, and Portable
The goLITE BLU features an easy-to-use touch screen and a digital, backlit clock with a timer so you can set the light box to your preferred wake-up time, allowing you to wake up more naturally and more refreshed. Use the touch screen to adjust the light intensity to your particular needs.

At just 5-1/4 x 5-1/2 x 1 inches (WxHxD), the goLITE BLU is compact and unobtrusive, allowing it to fit easily in your bedroom or your office space. It folds down easily, and because it's powered by a rechargeable battery (included), the goLITE BLU is easy to take wherever you need it.

The goLITE BLU is covered by a two-year warranty.

  • Portable, rechargeable blue therapy light with Bluewave.
  • Sleek new compact design
  • New diffusion optics for softer, even light
  • Wider treatment field gives you more flexibility
  • Fully programmable, adjustable intensity

Customer Reviews:

  • This really helps to regulate my sleep cycle.
    I'm currently preparing an international move and I found with all the stress that I was always tired. I'd nap for a couple hours every day and it would completely throw everything out of whack. I'd go from sleeping through the night to sleeping through the day and back every couple weeks. My husband has also just come off 3rd shift to days. We are both using the goLITE BLU and I can say it has really helped me eliminate the naps. I am now back to sleeping only during the night and up and refreshed during the day. This is a wonderful product! ...more info
  • Our Home's Become the Blue Light District

    As the caregiver of an elder with Alzheimer's disease, I had a two-fold purpose in mind for the Philips goLITE BLU Light Therapy Device:

    1. I hoped that the use of the light would improve the depression which frequently occurred as memory deteriorated.

    2. I wanted to test the theory that the BlueWave light could reset her circadian rhythm so that she slept more regularly and soundly.

    I researched these ideas on the Philips and Apollo (the original manufacturer) sites, but I wanted more evidence than they offered, so I went to the medical research literature. Here's a small part of what I found.

    Scientific studies

    Researchers at the Mood Disorders Clinic in the University of Utah Health Sciences Clinic compared the response of subjects under bright blue light compared to those of subjects under bright red light. Subjects under bright blue lights experienced significantly greater relief from either Seasonal Affective Disorder alone or Seasonal Affective Disorder combined with general depression than subjects under bright red lights.

    Researchers in the Department of Neurology at Thomas Jefferson University (Philadelphia, PA) also compared blue to red light therapy. Like those in Utah, these researchers found greater improvement in Seasonal Affective Disorder using the shorter wavelength blue light therapy than the longer wavelength red light therapy.

    In The Netherlands, researchers are currently initiating a study comparing the use of bright blue light to dim red light for relief of major depression (not Seasonal Affective Disorder) in subjects 60 years and older. It will be interesting to learn whether bright blue light therapy can have an impact on non-seasonal depression in the elderly.

    Using the light at home

    Because the light can be set to come on at specific times during the day, the light itself reminds us to use it. Although Alzheimer's patients often resist new activities, using the bright light has been easy for her, and, so far, she has not resisted using it. That the light is small and portable has made my life easier because I can set it up for use anywhere, any time.

    After a week, her sleep patterns have improved, and the depression appears to have lessened. I am recording her impressions of sleep quality and my own impressions of her depression every day. When a month or two of using this device have passed, I will update this review.

    In summary, it is clear that this device can be a significant aid for Seasonal Affective Disorder and some types of depression. Will it work for elderly Alzheimer's patients? Here's hoping....more info
  • Works for SAD
    I had struggled with SAD for years, having depression and anxiety all winter long from Nov-March. I received this as a christmas gift from my husband so I have only been using it for 5 days. For the first 4 days I was using it for 20 min on 50%. I did feel somewhat better. Today I decided to give myself a full blast treatment of 100% for 30 minutes and I have to say that I am noticing an huge increase in my mood and energy level. My summer persona has returned. My advice to anyone using it is to go at full blast 100% brightness. I didn't because I was afraid to overdo it but I think that was just holding me back from getting the full benefit. I am going to give it a try in the afternoon to because I tend to get a lag around 3 pm where I want to take a nap and then I get wired before bed time.

    The unit is intuitive and easy to use though I did have some trouble turning it on because you have to hit the on button twice, once to wake it up and once to turn on the lights. But really it is so easy and compact and portable with great features as well. So far, I love it. ...more info
  • Ray of Light
    I moved back to Wisconsin last year after being gone for 30 years. Last year we received over 100 inches of snow and had many gray days. This year I noticed in November that I was already starting to feel the effects of winter - insomnia some nights, sleeping more, less active, eating more carbs. In January I was online searching for natural ways to feel better. After thoroughly researching light therapy, I decided to order this top of the line product, and oh, by the way, I wanted it NOW! I ordered it on Inauguration Day and it arrived the very next day. I had to charge the unit for 8 hours so it would be the next day to try it. WOW, in capital letters! I started with 30 minutes a day at the 50% setting following the suggestions of the circadian rhythm assessment I had taken. After the first week I was down to between 12 - 15 minutes a day and I was feeling more energetic through out the day, sleeping more soundly at night and not napping. I call it my "beach in a box" and I plan to use it during the rainy days of spring and summer, as well. I do notice some "minor" problems when I turn on the unit. It sometimes takes 3-5 attempts to turn it on. A minor inconvenience and not worth sending it back. I am very happy with this purchase and I have recommended it to many of my friends and family who live up here. One last comment. I lost my job right before Christmas and have become a statistic of the economy. Deciding to spend the money for this was difficult. In the end, I decided it was cheaper than therapy sessions or a plane ticket to somewhere sunny that would only be a temporary fix....more info
  • Wonderful for Insomnia!
    I don't have seasonal affective disorder, but I've heard light therapy can help insomnia.

    Every morning I'd wake up completely exhausted. I'd feel like the living dead until about noon. Then when I'd try to sleep at night, I'd be wide awake because as far as my brain was concerned, I hadn't waken up until noon. It was a vicious cycle. For awhile I was on a prescription sleep aid, which helped but the doctor didn't want me to become dependent. Since then I've just had to go back to being tired during the day and not sleeping at night.

    Well, I've been using this light every morning for about 30 minutes for the past two weeks now. The light makes me feel much more awake in the morning. I no longer sleep on the train every morning going to work, I actually read and feel awake! By bedtime I feel tired again and I've been sleeping so much better. This light was a miracle for me!

    There's many features I like about it. I like that it can be used as an alarm, with or without a buzzer sound. I like that it has an internal battery that you only need to charge about once a week. You can adjust how bright the light is (I keep it at the lowest setting). Also, I wondered how long the LED lights would last before burning out, and according to the manual if you use it 30 minutes every day, it'll last 50 years. So, I'm sold! I wouldn't want to live without it ever again....more info
  • Wonderful, but read the instructions!
    I'm dubious of any machinery which claims to have a positive effect on your mood and sleeplessness.

    But I'm sold on this one!

    I've been using it for three weeks, and it's made a dramatic difference. I have more energy, sleep like a baby and have managed to maintain a better sleep schedule (which has been a problem for me.) It takes a little getting used to a new morning "habit," but my fifteen minutes in front of the light allow me to catch up on the paper and avoid the winter blues, so HURRAY!

    That said, I began operating it on its full-strength setting for the maximum suggested time. I figured, I'm tough, I can take it. But what I discovered were powerfully weird headaches which occurred a few hours later and lasted until I went to bed. I spent a little less time in front of the light, adjusted the setting to half-strength and PRESTO! No more headaches. The manual mentions all this; I didn't really follow it at first.

    It's pricey, no doubt about it. But the average life of this unit, according to the enclosed information, is probably longer than yours. So buy with confidence, read the instructions and follow the manufacturer's advice . . . and like me, you may have your happiest winter ever!...more info
  • Amazingly small but a very powerful light
    Watch Video Here: Many people feel a little less energetic in the winter, while others get the winter blues. It has been shown that the decrease in natural sunlight may be the culprit in this seasonal change on our bodies. In fact, it has a name - Seasonal Affected Disorder (SAD).

    The Philips goLITE BLU light is designed to help sufferers of SAD by mimicking the effect that the sun has on your body.

    A few pointers - tips about the light (Many were not included in my video)-

    - It uses all LEDs therefore it is very unlikely that any of the "bulbs" will burn out.
    - LEDs generate much less heat than other forms of light, so there is a very low risk of fire.
    - You must (on occasion) look into the light. The effect of the light works through your EYES and not your skin, therefore you must glance directly into the light (about once a minute for me).
    - The unit MUST be charged for 8 eight hour prior to the initial use.
    - There is no access into the unit - meaning there are no screws or bolts that can be used to access the light, batteries...etc.
    - Surprisingly small - probably measures 8"x8"x1" and weighs less than 2lbs.
    - Has a built in alarm feature.
    - Do not use two hours before you go to bed, since your hormonal response to the light may keep you from sleeping.
    - Built in timer lets you preset how long you want the light to operate (up to 1 hour)

    Final verdict - the Philips goLITE BLU is well designed and has loads of built in functionality. While it is not it not inexpensive it may very well hold the key to helping you feel more energetic in the winter months.

    5 stars.

  • A proven mood lifter - easy to use
    As a part of my work, I need to awake till odd hours, wake up early mornings and a lot of travel. All of this takes a toll on me and causes fatigue - I started blue light therapy about 3 weeks back and already started feeling better. It is probably going to be another 2-3 months before I can recognize full benefits - but for right now, I can vouch for the fact that it is a great mood lifter.

    Let me split this review into 2 parts - first about the blue light therapy and second about this device

    About blue light therapy
    Colors influence our mood to a great extent, if you were close your eyes for a moment and imagine a clear blue ocean - it is an instantaneous mood lifter. The effects of blue light is not a research subject, it has been proven to be very effective in research studies done [...].
    It is not only helpful for lifting your mood but also a bunch of other stuff for skin disorders.

    Pros (about blue light therapy)
    + Proven long term benefits to improve Seasonal affective disoder
    + Good to treat depression due to weather
    + Good for skin ailments such as Acne & Psoriasis

    About this device
    Buying from philips, as compared to any other manufacturer makes me comfortable in the fact that philips would have done enough research in making sure that the light is of the right frequency and that the unit comes with reliable and well tested components.

    Pros (about the device):
    + Touch controls to control the adjust brightness
    + Clock & Alarm clock
    + Nice carry case
    + Rechargeable batteries
    + Small & easy to carry

    - A bit pricey...more info
  • A rather nifty way to control your energy
    I have suffered from insomnia for years, and just recently have gotten control over this with the introduction of serotonin and dopamine into my daily supplements. So I have been sleeping good for seven weeks. I still am dealing with getting that dragging feeling part way through my day. I had been taking the 5 hour Energy drinks and they really help, but this light has taken their place.

    I wanted to try this last year but they wanted $250 for them. A bit much. Now the prices is down some and, for me, rather worth it. I just charge it, set it on my desk and it does the rest. If you have a hard time getting started in the morning, you can do half hour. If you start to drag in the afternoon, then another half hour wakes you up. I am both, so am doing first thing in the morning and the afternoon. Sometimes I do double doses if I am really tired. Works. It's now a WOW improvement at the start. It really took a full week to see the changes. Now I wouldn't do without it. I forgot to use it one day and felt fuzzy all day. Recalled my blue light, when to get it, then a treatment later, very awake.

    So if you have trouble with you sleep patterns, or energy levels, this is a viable alternative to energy drinks etc.

    I am really enjoying this and delighted to have tried it....more info
  • pretty cool
    Living in the northern latitudes of the US and enduring very short amounts of winter daylight, I thought the goLITE would be helpful. I don't suffer from SAD, but I do have sleep problems, so that is the issue I hope the light therapy will impact positively. I've used the goLITE for about a week now. Probably not long enough to really speak to its efficacy, but I think long enough to review how the device functions.

    The goLITE is a solidly constructed piece, attractive in a modern/clinical sort of way. The digital interface wasn't intuitive enough for me to figure out all of the features without referring to the instructions, but once I'd looked at them, it was easy to set up. The small metal post that inserts in the back as a stand is clever and the magnetic slot it stores in when not in use is a great design feature. I like the carrying case too, that makes it very convenient for the briefcase, though the charger is bulky and doesn't go in the case.

    I've programmed it to operate for 30 minutes a day as soon as I sit down at my desk in the morning. (I'd really rather wake up to it like an alarm, but since it comes on at full intensity rather than gradually, I think it would make me grumpy rather than raise my mood! Also, I'm not so sure my husband would appreciate it, since I get up earlier than him.) When in use, the light isn't bothersome in my peripheral vision even at maximum intensity, though the first day I had a bit of a throb in my head and eyes for a few minutes.

    There are only two negatives I can see to the goLITE. One, in my view it is quite expensive, more than I think it warrants. And, two, that when used as an alarm there isn't a gradual illumination to the desired light level.

    The goLITE is definitely a step up from the lights people wore on their heads in the early days of light therapy devices. I have hopes that it will help improve my sleep pattern so I sleep solidly the whole night, I think it's working but haven't really used it long enough to be certain. I'd recommend it to anyone who feels the effects of short, dreary winter days.

  • Wonderful
    I am writing this review for those of you that have had a 10,000 lux light therapy box. I needed to purchase a smaller light. I knew the white light worked, but wasn't sure if the blue light would work as good. I purchased my first light at Apollo. I had read the reviews about the blue light and decided I would try it.I purchased this one also at Apollo. You don't have to sit in front of the blue light as long as the white. I have had mine for two weeks now and am loving it. For me I actually think it works better than the white light. I don't find it any brighter than the white light. Doesn't hurt my eyes. I would recommend this to anyone wanting to purchase a light therapy box. The construction is good. Touch part works good. I sit in front of it for 15 minutes. I get three sessions out of the charge. The only complaint I have is with the stand you have to use it in the position it sits in. If you want to raise or lower the light you have to prop it up. I like having to timer so I don't have to keep track of how long I sit in front of it. I set the amount of time which is 15 minutes for me. And when the time is done the light goes off. I am glad I decided to purchase the blue light. ...more info
  • It works
    There is research that shows that light therapy is an effective treatment of the winter blues. In Scandinavia many people do it on a daily basis in the winter months. A session of 15 minutes wakes me up immediately, and after a few weeks I can feel a more permanent effect. I treat my whole family with the light therapy, even my dog. Everybody agrees that they feel the results after each session.

    I was surprised how small and portable this thing is, I was also surprised by a neat touch screen feature. The only negative thing is that the battery does not last very long. I have to charge it almost every day....more info
  • Where's the magic?
    I'll cut right to the chase: this product did not do anything for me. My mood was not elevated, I didn't sleep better, I wasn't magically more awake after using it for a month. In fact, nothing happened.

    That's not to say that this isn't a good, or even great, product. It did nothing for ME, so I hesitate to give it a review either way. Of course, it's also possible that the product is a perfect piece of junk. Really, I have no idea.

    However, I can say that the product is well designed and substantial. For the most part (except how, exactly, to turn it on) is pretty intuitive. And for something that looks like a miniature solar panel, it's decently attractive---with the look of an IKEA lamp (for insomniacs).

    I am disappointed that the product did not perform miracles, but products that promise such things rarely (if ever) deliver---the goLITE being no exception.

  • I was skeptical at first but...
    So after reading these reviews on, I was initially VERY skeptical about this product working. Most of these reviews come from people in the Vine program or the reviews were being released rapidly over a short time period and that had me very doubtful.

    But before I go into that, let me give you a little background on my personal story. I am 21 years old, Indian-American (and thus my body's genetic makeup is probably not appropriate for the cold winters of Vermont), and I've been having sleep problems since the age of 13 or 14.

    For years, I would sleep in and miss classes, and would generally feel chronically fatigued and apathetic. I thought I had ADD/ADHD, so I self-diagnosed myself by eating better (lotta veggie, 2-3 cups of green tea, 2 fish oil pills, meat, not eating out, etc, exercising better (3 days of lifting, 3 days of HIIT running).

    My problem got pretty bad to the point that I would miss important meetings or events. I was focused, and hardworking but I just could not wake up on time (and go to bed on time either)!

    I would go to bed at say 11 PM, yet I would still wake up at 12 PM or 1 PM the next day. I would be like what the hell.

    So then over this winter break (where I had a good 5 weeks off), I started letting myself go to bed at the time my body NATURALLY fell asleep (not when I *wanted* to). I found that I was going to bed at 3 AM.

    And what happened? I STILL woke up at 11 AM!!!!

    What did this show me? That I WAS getting 8 hours of sleep BUT it was at a later time (hence going to bed at 11 PM didn't do anything because I really wasn't falling asleep until 3-4 AM in the morning).

    So why did this happen? Why did my sleep schedule get delayed (this problem is called DSPS or delayed sleep phase syndrome --- it's nothing serious it's just a big pain when trying to function in society, a normal 40 hour job, etc. etc.)?

    Well in high school I had bad habits. I would go to bed late playing VIDEO GAMES, watching TV, doing intellectually stimulating activities that would make me stay up late.

    Also the summer before college started, I had a job where I was working as a busser at night (4 PM-10 PM) or (6 PM-1 AM), and thus I was sleeping later.

    Also, genetics is probably at fault too. My dad has this problem but not as bad as me (I think this is also because he's a lot older, and he's been working decades waking up at 5 AM for work that his body got FORCED to wake up then. Nevertheless, he is always chronically fatigued, and if given teh freedom to wake up when he wants would wake up at 9-10 am or so).

    Anyways, before I digress any further, this winter break, I let my body go to bed when it wanted too. But then something bad happened. I was going to bed later and later every day (going to bed at 8 AM!!!). And thus, I would end up sleeping my 8 hours during the DAY!!! It was terrible. So I looked into chronotherapy, and I did something where I would go to bed a little bit later every day (so instead of going to bed at 8 am the next day, I would go to bed at 11 am, then 2 PM, then 5 PM, then eventually 8 PM), and let me assure you it was the most DEPRESSING and MISERABLE experience of my life.

    Staying up for a good one and a half weeks at night, with no contact with anybody else, and getting even less sunlight because I would be up at night and sleep during the day affected my mood, made me irritable, cranky, and at times manic.

    SOOOO, I got desperate and started doing research online and learned about light boxes and how they were effective treatment for these circadian rhythm/SAD problems.

    It piqued my interest and I eventually found this product (Apollo was the company that makes these products, but Philips bought them over).

    I was getting desperate because school is starting in a week, and my sleep schedule was still messed up so I ordered this thing and used 1-Day Fed-Ex shipping (and I never do that, I'm a poor college student LOL).

    Immediately after the first session, I found that I was waking up at 5-6 AM NATURALLY and going to bed at 9-10 PM PHYSICALLY/EYELID HEAVY SLEEPY.

    WOW. WOW. WOW.

    I also felt happier too and the reason why this happens is that the blue light increases the production of SERATONIN (the happy go-lucky hormone that is low in depression, etc).

    I'm a senior now majoring in biology, and I'll briefly go into the details of the basic physiology of blue light.

    Basically, your eye's retina (a thin membrane at the back of the eye-ball) has a couple of receptors. The ones you've probably heard of were the rod and cones.

    Well, there's another one called the "MELANOPSIN" photoreceptor that scientists about 10 years ago discovered. And these are on the edges of the retina (not centric like the rods and cones).

    These melanopsin photoreceptors absorb light of a specific wavelength and that is BLUE (460-480 nm).

    Older light boxes used white light (which contained blue light) that mimicked light from the sun, but apparently those are superbright.

    So why can't you use a regular old BLUE lightBULB then? I don't really know maybe someone can comment on this as I'm not a physicist.

    Other notes: This thing is expensive, so if you want something a BIT cheaper you can go with the slightly older Philips/Apollo units some of them are as low as $80. I bought this one, I'm not going to lie, because of the ipod-esque/futuristic features (plus apparently the light on this unit is supposed to be a lot softer then the earlier ones [where people would often get headaches, eye pains, etc]. Some people have expressed concerns about macular degeneration and other eye damage that can be associated, but all the literature that I read showed that this was due to HIGH INTENSITY light being used for 6 HOURS a day for a time period (don't remember how long). The Philips GoLite Blue unit claims to be safe, and the other thing is that you're only going to be using it for 15-30 minutes in the morning anyways.

    Ok, this review is getting long, so I'll end this on one specific note and that is it feels great to be able to fall asleep like everyone else and to wake up at 6 AM in the morning (even on the weekends!) NATURALLY.

    If you have problems waking up on time, have chronic fatigue, depression, SAD, ciracadian rhythm disorders, then this is an EXCELLENT investment on your quality of life.

    P.S. You might be able to make a deduction on this unit with your health insurance or through your taxes, just a heads up, but I'm not 100% as of yet. ...more info
  • Shiny Happy People
    Disclaimer: I am generally an upbeat, energetic person and live in South Florida, so the Philips goLITE BLU may not seem like a great fit for me. However, I do work in a dark office for most of the day and sometimes have trouble sleeping through the night, so I figured I'd give BLU a try.

    It has been a little over two weeks but I can honestly say that I've noticed a difference. I am sleeping more soundly and have stopped waking up at 3 or 4 AM just to lie there restlessly for an hour. So however it does it, it's working. I keep it on my desk at work and give myself a 15-30 minute session first thing while checking email and drinking coffee. It could be the coffee, but I would swear that I feel more perky first thing during the morning. My energy levels have stayed constant during the day. Before using BLU, I occasionally would get the mid-afternoon yawns.

    Falling asleep has never been an issue, but staying asleep come 3AM has been. Since BLU, I've been sleeping until the alarm goes off. Speaking of alarms, goLITE BLU has a good one that uses either a chime, the light, or both. I have to admit, it is a nice way to wake up in the morning.

    The size of the unit is nice, very portable and it comes with a leather travel sleeve. The unit housing is very sturdy and the LEDs are said to last about 50 years with normal use. I don't foresee needed another, hahahah. I've found the charge to last me about a week -- longer than the manual claims.

    Of course, there has to be SOME flaws, but nothing really glaring (sorry). Yes, the light can take a little getting used to and I find that higher than 50% is too much for me, even with it being in my peripheral vision. The LED display is nearly impossible to read when the unit is on, and unfortunately you must look right at it when changing the light output level. It takes about 3hrs to recharge which seems a little excessive, but not too terrible. Lastly, at around $250, this is NOT an impulse buy item. There are cheaper units out there and perhaps one of those will suit the needs of someone on a budget better. goLITE BLU is a quality product though -- well thought out and down to the neat magnetic stand.

    If you or someone you know is effected by Seasonal Affective Disorder or has trouble sleeping and wants something portable and/or with a small footprint, then I would say that the Philips goLITE BLU should be on your short list of choices....more info

  • Let There Be goLITE !!
    What a wonderful product! I bought this for my husband about a month ago and have no regrets. For almost 30 years of our marriage he has suffered with seasonal depression. Ohio winters can be quite dark and gloomy. A friend of mine has SAD and recommended getting him a "light box". So began my quest for information about SAD and light therapy. After much research I decided to buy the Philips goLITE for him. After 2 weeks he noticed his outlook and mood was much improved. He loves how easy it is to use and the fact it is so portable; you can literally use it anywhere. He wouldn't be without it now. I understand the older version of the light boxes were the size of a small suitcase! I highly recommend the Philips goLite. It was well worth the investment. My husband feels so much better now. I just wish he would have had this years ago. Four thumbs up here!! ...more info
  • Seems to Work for Me
    The Philips goLITE BLU promises more restful nights and an end to winter woes. It's difficult to really know how effective this light therapy is without performing my own double blind group study, but I did notice a marked improvement during my first 3 weeks. Despite the cost, I would recommend this light therapy device for anyone with seasonal affective disorder. Also, though I can't attest personally, it should help anyone who travels across time zones or changes their sleep schedule frequently.

    The goLITE BLU has a handsome, even cute, moder design. Despite thin being in, I didn't mind it's moderate depth. The included magnetic bar stand slips easily from a recessed magnetic storage groove into the back of the unit to provide a good (albeit fixed) angle. The control panel, located on the bottom third of the unit, is touch sensitive, intuitive and easy to see under any lighting conditions. However, features like an SD card reader or fm receiver would have made this a perfect replacement for my clock radio. I also would have liked a way to hang the goLITE BLU in my shower so I could get in my light therapy more conveniently. As it is, I've been setting it to go off 20 to 30 minutes before my alarm and soaking up the rays in bed. Overall, the quality of the build is extremely high and the aesthetics are equally well thought-out. The options for the timer, intensity and alarm are all excellent features as well.

    Before I began my daily light therapy, I was entering my least favorite phase of seaonal affective disorder. With a light haze of depression hanging over me and a disposition to sleep from 12:30am to 8:30am, I hoped my new little device would help me adjust better to the reduced winter daylight. I noticed little, if any effect during my first week. During the second week, I started feeling more energetic and less generally depressed, despite reducing my excercise slightly due to the freezing temperatures. Finally, after this third week, I'm waking up easier before sunrise, although not quite as easy as during the Summer. I'm not sure if my circadian rhythm has shifted much, but I do have more energy even when I miss a little sleep....more info
  • Better than a cup of coffee in the morning!
    I'd never tried anything like this before, and wondered if it might just be a gimmick. After several days of use I'm convinced it's no gimmick -- fifteen minutes of blue light directed towards my face (not in the eyes) while I'm reading really gives me a needed pickup. I use it in the morning when I wake up, and sometimes in the afternoon.

    I don't expect it will be necessary all year round, but I do find that -- even though I live in Florida -- my moods tend to shift during the winter and that light therapy seems to put me in a better mood even on a (relatively) cold and overcast day.

    Admittedly, I haven't done anything like clinical trials and so this is anecdotal evidence -- all I can say is that if this is a placebo, don't tell me, and let me keep enjoying the benefits I seem to feel.

    Apart from the Blu Light Therapy, this is a neat-looking alarm clock -- and it has a wonderfully delicate chime. It is loud enough and distinct enough to wake me, but it doesn't grate on me like ordinary alarm clocks. I don't wake up to it feeling alarmed but as if I'd been gently awoken by a friend. It is a bit pricey, perhaps, but I've really enjoyed my goLite over the last several weeks. I'd recommend it. It would make a very nice gift for a loved one -- especially one who lives in wintry climes. ...more info
  • I tried it - I'm keeping it!!!
    I would surely recommend this. I have suffered from "the winter blahs" for years - about mid-to-late January I lose motivation to do anything but what's necessary (i.e. - work, laundry, cooking, etc.). I've had this Phillips goLite BLU for about 3 weeks and I can tell the difference. I no longer have that exhaustive feeling (like after a good cry) and I'm not so irritable and have found some motivation again. I won't claim this has fixed my symptoms completely but it has definitely made a difference in how I feel. I bought it knowing I could return it within 30 days. I'm keeping it!!!...more info
  • A Must Have for Northern Winters
    I live in Northeastern Wisconsin where the winter drags on from the beginning of November until April. I happened on a review of the goLITE by accident, and thought it would be a definite help for me. Most winter days I feel like crawling into bed around 4 p.m. and staying there until the next morning.

    I found the goLITE very easy to use after reading through the directions once. I have it set as an alarm on the nightstand next to my bed. After I use it in the morning, I bring it downstairs with me and place it on the breakfast bar while my children eat breakfast. Some days I also use it again in the afternoon.

    Within about 2 weeks I noticed I was sleeping better and having an easier time getting up in the morning. I also have more energy and accomplish more during the day. Even though the goLITE was expensive, I feel it was well worth the cost for someone who lives in a cold climate....more info
  • Great, especially for travel
    This is a fantastic light therapy product to buy for travel. It's so small, light, and pretty sturdy -- you can just toss it in the suitcase or carry-on. The light itself is different, but nice. I am used to 10,000 lux light, so just the blue spectrum gives off an interesting glow. And it does seem to work quite well. I only gave it four stars because I still like the big 10,000 lux light a little better for my purposes for the days when I'm not traveling. However, I don't use the light for SAD; I use it for my circadian rhythm disturbance, with the intent that the light will wake me up every morning. For that purpose, the super-bright 10,000 lux light is little better, I think. But for travel, this little goLite Blu is perfect!...more info
  • I Don't Think I'm One of the People That Needs This
    Almost all the Amazon consumer reviews of this product have been positive and that leaves me wondering if I am missing something. I've used this light therapy device daily for two weeks and haven't noticed any difference whatsoever.

    That said, I need to qualify this review by telling you that I have never experienced "SAD" or depressed feelings from cloudy days. Also, I live in Southern California so we don't have that many non-sunny days to begin with (I wish we did). So maybe I am not the type of person this device was made for.

    The product itself appears to be very well made - nice and sturdy, the quality is apparent. I am not sure why it is so very expensive, though. Does it cost that much to produce this kind of blue light? It has a nice alarm and countdown function, as well as a clock, and the light adjustment feature works very well. The panel is slim and unobtrusive. It has a removable stick stand in the back that attaches to the panel when not in use. My only complaint about the engineering is the placement of the on/off switch which in my opinion is in a place where one would naturally clutch the panel to pick it up. I've turned it on accidentally several times because of the location of the button.

    I followed the directions for this device, placing it off to my left side about 20"-25" away from my face on my computer desk, set it to 50% intensity and timed it to stay on for 30 minutes. Initially the light seems very bright, like having a bunch of blue LED's shining in your face, but I quickly got used to it and really didn't notice it after a few moments. I noticed it mainly when the light went out because the room seemed so dark all of a sudden.

    Did I feel energized or did I notice any change in my sleep patterns or any difference at all? Not really. Nothing that I can attribute to this light panel since I noticed no consistent changes. I felt pretty much the same as I always do.

    Personally, I think that the biological composition of some people naturally lends themselves more to being positively affected by this device, but I am not one of those persons. I'm going to continue using it and if I do notice a change, I will update this review. ...more info
  • Let There Be goLITE !!
    What a wonderful product! I bought this for my husband about a month ago and have no regrets. For almost 30 years of our marriage he has suffered with seasonal depression. Ohio winters can be quite dark and gloomy. A friend of mine has SAD and recommended getting him a "light box". So began my quest for information about SAD and light therapy. After much research I decided to buy the Philips goLITE for him. After 2 weeks he noticed his outlook and mood was much improved. He loves how easy it is to use and the fact it is so portable; you can literally use it anywhere. He wouldn't be without it now. I understand the older version of the light boxes were the size of a small suitcase! I highly recommend the Philips goLite. It was well worth the investment. My husband feels so much better now. I just wish he would have had this years ago. Four thumbs up here!! ...more info
  • Nice ... but I'm not sure it's worth the price
    I've suspected for years that I might have a touch of SAD (and it's been suggested to me by a doctor, as well), so I was excited to finally try out a light-therapy device.

    Well, it's winter in Michigan, and I've been faithfully using this little guy every day, but I can't say I'm seeing a difference in my mood. I usually turn it on and sit in front of it for 20 minutes every morning while I eat breakfast and do some reading. It definitely helps wake me up (which, believe me, is welcome!), but I'm not seeing any changes other than that. However, I'm also VERY pregnant right now, so it's possible that I'm just so hormonal that nothing helps! I'll continue using the goLITE and update this review if things change after the baby is born.

    Overall, this is a nice little device. It seems sturdy, and I love the little stand on the back that easily pops on and off for easy storage and/or use. (The fact that it's magnetic is awesome! I know for sure I would have lost it by now if it wasn't ...)

    The controls could be a little more intuitive, though -- for example, the alarm kept going off (I didn't want it to), and every time I was sure I'd figured out how to shut it off altogether, the next day, it would go off again. I'm no techno-wizard, but I am fairly competent with most gadgets, and even reading the manual, I was still confused. (Eventually, my husband figured it out ... I think. We'll see tomorrow!) Incidentally, the alarm is quite pleasant. I don't use an alarm clock most days, but I imagine that if I did, the light and alarm feature would be quite a pleasant way to wake up.

    Bottom line: Right now, I can't recommend the goLITE for those with SAD. However, if you're looking for something that will help wake you up or just give you a burst of light on a gray day, this little guy might be your answer. But it's not a cheap answer....more info
  • Effective Treatment for SAD and morning fatigue
    I have to admit, I had my doubts at first. Light therapy was first suggested to me by my medical practitioner a few years ago to help combat sleep problems and seasonal affective disorder. Fall always brought about the usual blues. Shorter days, dreary weather, and the cold all made me feel (for lack of a better word) blah. It was also next to impossible to wake up. I'd hop right out of bed in the spring and summer, usually before the alarm sounded. However, fall and winter make it a chore to wake and the snooze button becomes my best friend. Well, I finally had an opportunity to try light therapy and I must say the effect was almost instantaneous. I'm not a big caffeine drinker but the effects of this light (at least to me) are comparable to drinking a can of red bull. I feel more energetic within 15 minutes after finishing my therapy session. I feel more alert and more willing to stay active. Most importantly, I feel happier and more spirited. I always knew the sun had this effect because I previously worked the overnight shift at a job located 65 miles west of my home. On the mornings following my shift, I would drive home for over an hour eastward with the sun shining directly into my face. When I arrived home I always felt refreshed, energized, and not at all like I had just worked all night without sleep. Well, those days are over, however, I'm usually at work before 7am. The GoLite is a high quality replacement for my missing morning sunlight in the fall and winter. I'm usually at my desk using my GoLite before the sun even rises. The build is very solid and high quality. It is also very portable and can easily be carried with you daily. The GoLite is also very easy to use. Battery life is impressive. I can get over a week of ? hr or more treatments on a single charge. Programming is simple. You set the desired session time by pressing the timer button and using the plus/minus buttons. Once set, your session time is retained in memory. When you are ready to begin a session, just position the GoLite on the stand, push the power button on the side, and begin your session. The timer will begin to count down and the light will turn off automatically at the end of the session. Meanwhile, you're free to do whatever you please during the session while the light shines on your face and does its magic. It is highly addictive. When the light is on, it gives the sensation of sunlight though your peripheral vision. The blue light is soothing and not harsh on the eyes or distracting. So far, 1/2 hr at 50% intensity is good enough for me, although time and intensity can be increased or decreased, depending on your response to treatment. If you go to the manufacturer's web site, they have a short questionnaire that you can take to determine recommended treatment. I feel a lot better in the mornings after treatment. It's also becoming easier to fall asleep at night and wake in the mornings. My mood has improved greatly as well. Like I said, I was a skeptic in the past but GoLite made me a believer. So far, it's the best way I've discovered to combat the winter blues....more info
  • Guess I have the Southern California Blues
    I wish I could say "Not Sure" instead of giving out a star rating. Basically, this goLite has had no effect on me even after everyday use for 2 weeks. I see that it might work best for people with circadian rhythm (internal body clock) issues and don't see the sun much. I live in Southern California, where the sun shines a lot, even in winter, so maybe it doesn't have any relative effectiveness. I wasn't sure what to expect when I requested this product for review. Now, however, I believe the target audience must be aware of circadian rhythms and the various ways to regulate them. Light therapy is, from what I read, one possibly effective solution. I would have to doubt it would have any effectiveness if you already get lots of sun, though. So, again, I really think anyone interested in buying this must already be read up on what light therapy is used for and not just looking for a way to beat "winter blues," "lack of energy," "sleeplessness" and any of the other many things it says it is good for. If any of those issues are not caused by circadian rhythm issues, then this might not be the solution. Personally, at one point in my life, I had many of the problems this product says it addresses, but I overcame all of them by starting a regular exercise program. So, before you buy, do your homework and figure out if a circadian rhythm issue might be causing your problems. If so, then this product might help....more info
  • great light therapy
    I recently purchased this product to help with some symptoms of seasonal affective disorder. As a therapist, I have noticed the signs for a couple of years (decreased energy, feeling sad more often, increased tiredness and changes in my sleeping pattern, all during the winter months). Within only a few days I could begin to feel the effects. My mood has improved, my energy has increased and my sleeping is back on track. Not only is it effective but I have had no trouble fitting it into my routine. I usually just use it when I'm putting on make-up in the morning or eating breakfast. I was a little concerned about some side effects based on other reviews, but I have had no trouble with the brightness of the light or headaches even though I too have light eyes and am prone to headaches. Overall this is a quality device that is worth the cost....more info
  • Has increased my concentration at work
    I want to start by saying that I do not have SAD. I do have chronic insomnia and was anxious to try this product out to see if there was any difference in my sleep patterns.

    I am still not sleeping every night. On the nights I do manage to fall asleep, my sleep is deeper and more satisfying. I'm not as groggy and I do sleep straight through the night instead of waking up at 2am and being awake the rest of the night. There are still nights that I just don't sleep at all. I'm hoping that will change with continued use.

    My concentration level has increased. I decided to conduct my test at work. For the past month, I've been using this product at least once each work day for 15 minutes at a time. I started off on the lowest intensity level and adjust up on some days.

    The claims are correct. I could tell a difference in one work week. I would often use the goLITE first thing in the morning. I get into work so early that it's still dark outside. After a few days I noticed that my concentration and focus increased. This also increased my productivity. If I don't remember to bring the goLITE home on the weekends, I notice that I feel as if something is missing.

    After the second week I started turning the Philips GoLITE on after lunch as well. I can now make it through the day without any type of lag whatsoever. On days where I feel more stess than usual, I adjust up the intensity of the light. Not sure if it actually does more but it makes me feel better just to do that.

    This item features an alarm function that will turn the blue light on at a specific time. I don't usually use this feature but did try it out a few times to see how it worked.

    The intensity of the light has a adjustment feature. I started off on the lowest setting. The very first day I used it, I did get somewhat of a headache. I repositioned the unit and was fine the following day. It took two or three days to get used to the military time readout on the clock. That's a minor thing though.

    Overall, I love this product!! In fact, if I was asked by the Vine program to return it. I would immediately order one to replace mine. It is well worth the investment. ...more info
  • Certainly Not A "Cure-All" But Provides Some Help With Seasonal Affective Disorder
    I was very excited about receiving this product because for as long as I can remember I have had problems battling "Old Man Winter" here in Northwest Ohio. I know I have SAD (Seasonal Affective Disorder)and for several winters have went to a tanning bed once a week to receive light therapy. Now in my late 30's and noticing the skin damage done by tanning beds, this light therapy from Philips is certainly a better and healthier alternative that I can use everyday. The unit is very functional and has touch screen ability. It has a timer, alarm and clock. I would throw out my OLD CLUNKY alarm clock if only the GoLight had a radio installed or a port where I could plug my IPod in at since I like to wake to music every morning. However, the alarm on the GoLight is a nice chiming alarm and not at all annoying. I really love to wake to the blue light in the AM and then I take it over to my computer desk to sit in front of the light for the 30 minutes that I need. I use it for 30 minutes a day at 75% strength and find it only mildly helpful for my "winter blues". It is hardly a "cure-all" for me, however, but might work better for someone who has Subsyndromal Seasonal Affective Disorder which is a milder form of SAD.

    People with full-blown seasonal affective disorder experience serious reactions when summer shifts to fall and on to winter. With seasonal affective disorder, fall's short days and long nights may trigger feelings of depression, lethargy, fatigue and other problems. Because increased sunlight improves symptoms, light therapy is often a main treatment for many people with SAD. Light therapy mimics outdoor light and causes a biochemical change in your brain that lifts your mood, relieving symptoms of SAD. Light therapy is generally easy to use and has relatively few side effects.

    There's no known way to prevent the development of SAD. However, if steps are taken early on to manage symptoms, it may be able to prevent them from getting worse over time. Start treatment before symptoms would normally start in the fall or winter and then continue treatment past the time symptoms would normally go away. If you can get control of symptoms before they begin, you may be able to head off serious changes in mood, appetite and behavior that can disrupt daily life.

    Seasonal affective disorder IS a type of depression, and it can severely impair your daily life. That said, treatment -- which may include light box therapy combined with drug therapy-- can help you successfully manage seasonal affective disorder.

  • Amazing little lightbox!
    I was officially diagnosed with SAD in 1995 (by Dr. Rosenthal & his team at NIH). Wasn't news to me. Back then, full-spectrum lightboxes were expensive and bulky-- mine was the size of a office ceiling lightpanel. Not something you could take with you!

    This goLITE is amazing. The blue light really works, in less time than the old lightboxes, and the programmable unit is very easy to use. Since the literature is now advocating morning light sessions, I'm glad I can take this along with me to use in my office. (I used to use my old lightbox whenever I was home during the winter. Not necessary with the blue light!)

    Great product, easy to use and take along. Still not a nice warm sunny Caribbean beach, but it sure beats the old lightboxes.

    Highly recommended....more info
  • Ray of Light
    I moved back to Wisconsin last year after being gone for 30 years. Last year we received over 100 inches of snow and had many gray days. This year I noticed in November that I was already starting to feel the effects of winter - insomnia some nights, sleeping more, less active, eating more carbs. In January I was online searching for natural ways to feel better. After thoroughly researching light therapy, I decided to order this top of the line product, and oh, by the way, I wanted it NOW! I ordered it on Inauguration Day and it arrived the very next day. I had to charge the unit for 8 hours so it would be the next day to try it. WOW, in capital letters! I started with 30 minutes a day at the 50% setting following the suggestions of the circadian rhythm assessment I had taken. After the first week I was down to between 12 - 15 minutes a day and I was feeling more energetic through out the day, sleeping more soundly at night and not napping. I call it my "beach in a box" and I plan to use it during the rainy days of spring and summer, as well. I do notice some "minor" problems when I turn on the unit. It sometimes takes 3-5 attempts to turn it on. A minor inconvenience and not worth sending it back. I am very happy with this purchase and I have recommended it to many of my friends and family who live up here. One last comment. I lost my job right before Christmas and have become a statistic of the economy. Deciding to spend the money for this was difficult. In the end, I decided it was cheaper than therapy sessions or a plane ticket to somewhere sunny that would only be a temporary fix....more info
  • If you have the blues, simply add some more blue.
    I'm so hesitant with my review as it will not sound so positive. But I trust my issue is isolated. I just wish I could resolve it to share the resolution. Therefore, I will start with my problem.

    I had this a couple weeks now, and due to the season, have not had much time to enjoy it. My only free time is spent either online, watching TV, or Playstation etc... all of which works with my broadband connection, and that is where the drama begins. After reading the instructions (very easy) I did what was suggested and placed the unit by the side of me while on the computer. I never have internet connection issues, but moments after turning it on, my internet disappeared. However, I was not thinking about the GoLite at all. Never even considered it was the reason. I set the light for 15 minutes, and well, after about 20 minutes of cursing and frustration with cable wires and turning my modem on and off, and the computer... and testing Tivo etc. etc... let's just say I was experiencing the extreme opposite. I got the internet on again, and again, did not associate it with the GoLite. So, after exhaling I decided to try again. Turned it on, sat back, and yet again, internet is out. A few more curses, and half-way back to my modem I thought... could it be?... the blue light? I was not convinced that it was the fault of the unit, and just called it a coincidence. So, I later tried it in my bedroom, but you are not supposed to use it before bedtime. But, yet again, internet went out. This noticed after getting logged out of Playstation repeatedly. --- I waited a week, and case closed, if I turn the thing on and want to use the internet, I cannot. I have never had one of these before, so I don't know if this is common. But, it's upsetting to me because I would like to use this while I am working because I miss out on a lot of daylight.

    With all that babble aside, the GoLite is in fact very cool, and very effective. In my case, it will force me to relax more as I clearly will have to make myself read. I could watch TV, but my Tivo is connected to the internet. Not a huge deal there as it will connect anytime. I am just avoiding other electronics around it for now until I figure the problem out.

    There is indeed a calming aura and the positivity that daylight brings. It is perfect for those stuck in an office or possibly bed ridden people, the elderly, hyper children, the possibilities are endless. Imagine a nice bath with this as your light... someday I hope to try that! On a personal note, I did bring this to my therapist to discuss, and she said she had the same unit, but an earlier model.. and was envious of this one. It is very cool looking, has a great case for portability, a rechargeable battery to get you through a few sessions, along with a clock and nifty stand that pops out. You customize everything to your desire, be it brightness or the session time. There is even discussion on how this improves skin conditions and preventive aging aspects. Fascinating.

    It takes several weeks to realize the effects, and I have only had a couple weeks time to use. But in that time, I really do enjoy it, look forward to it, and have hope that it will improve my quality of living .... even without the internet.

    *** 02/21/09: UPDATE: I just wanted to update this review since I have used this for about two months now. I have to say that it is quite a welcome addition to my home office. My main adjective that I can exclaim is "refreshing". It has become a routine when I start my day in front of the computer, and more than occasionally during mid-day. I have a problem with natural light in my office, and this was the perfect resolution to the problem. I'm not saying it cures depression, obviously, but it does make the day a bit more tolerable and less stressful. I am a cynic and chronic pessimist, so for me to say a a blue light does anything is big. Well, the result is bigger. Very happy... literally.

    Of course, I did mention interference with my modem which I could not understand, or believe it had anything to do with this. But, alas, it did. It's all about where you put it. I simply put this a bit higher on my bookcase, and it completely changed everything. I don't understand why, but just a couple feet higher, and all is well. So, if for some reason you run into this very rare issue, simply try different areas of the room. It will be annoying to keep restarting the modem etc. but after a few tries, that's all you need to continue using the unit without any problems. The following is text from the Phillips user guide that is available online to view.

  • Bright Unit Keeps you Bright
    First let me be upfront and say I was a skeptic on this unit. However from reading and personal experience that in the winter months and cloudy days when there is less daylight I always have to give myself that extra "push" to get through the day. However be it that I ended up believing in this unit or it works, I do feel more energetic after using it.

    First on opening it, you have to charge it for 8 hours. And it comes with a small padded carry bag. The screen on the unit is a touch screen (other than the on/off button which is on the side) and you make all unit adjustments through the touch screen which is very easy to use. There is a timer, a demo mode and way to adjust the brightness of the unit (it's BRIGHT!!) so I've kept it on the lowest so far.

    I use it in the morning while eating and reading the paper. I keep the unit at an angle to my eyes adjusted up. This also is what the directions say to do.

    In ending, I can't say if it's mind over matter or if this BLU Light device is doing it, but after using it for about a month I can say something is keeping those "blue Blaahhs" away. ...more info
  • Extremely unintuitive controls but nice compact easy to travel with design
    I'm not going to review this based on whether it works or not, as that's such an individual thing. I have no doubt that many people will see obvious results from using a blue light, and others might not. I don't know if I suffer from SAD, but I do spend the majority of my time indoors as I work from home, so I felt this device would have benefits for me even if they weren't readily apparent or not.

    What I cared most about was how nice it was to use, was it easy to set up, compact for travel, etc. And the physical design of the device is very nice. It's relatively small and compact, and yet very sturdy and well made. It doesn't have a cheap plastic feel but has a quality construction that should hold up well for years. It comes with a stand that clips onto the back of the light, and a case to carry it in for travel. It is rechargeable and should have plenty of power for most trips without needing to bring the power adapter along, which is a BIG plus.

    Now, the downside. The controls on this device are some of the most unintuitive I've ever seen or used. I am a techno-gadget freak kind of girl, I work with computers for a living and can work and install the vast majority of electronic devices without ever opening the manual. This Philips light fell into the category of devices that the controls are a total mystery and I would repeatedly have to refer to the manual for even the simplest of tasks. At some point I seem to have set an alarm on it where it goes off every night automatically and I've yet to be able to figure out how to change this or turn it off. It just continues to go off and I tried unplugging it in the hopes that the battery would eventually die and maybe reset it and weeks later it was still going off! Well, I can say it sure has good battery life, but the controls really could use some work, it reminded me almost of a logic puzzle to try and figure out how to turn that darn alarm off.

    So overall, 5 stars for the design and features, 1 star for the very confusing controls. ...more info
  • Miracle Cure for the Winter Blues
    The Philips goLITE BLU Light Therapy Device has been effective in treating the "winter blahs". I find that when the weather gets cold and dreary, I become moody and a little bit depressed. The goLITE BLU provides the benefits of sunlight without the sun (or harmful UV rays). The science of this has been proven - I won't go into details here, but research it if you are interested. Philips' website for this product has a lot of good information. For me personally, the benefits have been that I sleep better and I wake up feeling more refreshed. My mood is much improved and I have more energy.

    Fitting the goLITE BLU into your daily routine is very easy. I set a timer for the light to come on when my alarm clock goes off (after one "snooze" on the alarm clock). I have the BLU light on my nightstand and I get my light exposure while I check e-mail and the weather on my cell phone. It runs for 15 minutes and then shuts off. You can set it to come on at any time, set the length of time the light stays on. You can select between the light just turning on, or the light turning on plus an alarm. This makes it easy to use for both an alarm clock and a light timer (though there is no "snooze" button). I've been getting up earlier and feeling better. I no longer need to drag myself out of bed and have a few cups of coffee before I'm a "human being".

    The goLITE BLU itself is small, has an ingenious stand that magnetically stores in the back of the device when not propping up the unit, and a leather carrying case. I leave mine plugged in all the time on my nightstand, but you can charge and use without the a/c adapter plugged in. This would be very easy to travel with as it's a nice small size. I think the Philips goLITE BLU is well worth the investment - life's too short to spend 1/4 of the year with the winter blues.

  • Mild effect- if any
    The Philips goLITE BLU is very well made. It comes with a slick leather carrying case. The device's stand magnetically sticks in a groove in the back of the device which is a nice feature and will prevent it from getting lost. Functionally the device is very easy to use. You can set it as an alarm if you like to wake up to the blue light. The device also has varying levels of intensity from not-so-bright to WOW-very-bright!

    Ok enough about that- I bet you're all asking, "well does it work?" Let me first say that I am not one to get depressed over gray winters. I live in Seattle and it is gray for more than half of the year so I do frequently long for some sunlight but I can handle it. I wasn't exactly sure what to expect from this light. I've been using it for two weeks now and I have noticed a slight effect. I find it a little easier to get up in the morning and am possibly a little happier than usual on my way to work in the cloud/rain. This could entirely be a placebo effect, but to re-iterate it has only had a very mild effect. That said I am sure there are people out there that need this device a lot more than I do. Judging by the other reviews I do believe it can really help them; but for those of you who don't really have any "seasonal affective disorder" don't buy!
