Customer Testimonials
  "I've always been a bit skeptical about SAD lights in general, and they've always been so expensive. I liked the simplicity (and price) of the Syrcadian Blue design and I spend most of my day in front of a large computer screen, so I gave it a try. I've been using it in the mornings for 90 minutes for 2 weeks, and I can't believe how good I feel. Non-invasive, no drugs, and I feel better - all day long. I'm only disappointed that I didn't have this years ago. I would recommend it to anyone. Thank you so much. I feel so alert, and more on top of things."   "This device works and works well. It doesn't require any change in your habits whatsoever, which is always the best way to ensure you'll use something. My doctor likes that it is at an appropriate and consistent distance from my eyes. I was also pleased to see that there is recent research published that shows that light therapy is almost exactly as effective as Prozac. A big positive in my book is that this a one-time expense and doesn't require repeated visits to a doctor and refills at a pharmacy."

  "I bought this because I work in a room that has only one window and I am unable to leave the room all day long. I bought this light based off the reviews and size. I have small desk space so the feature where is can be fitted to the top of the monitor is a HUGE plus! I have used it now for about two weeks. I HAVE noticed that I don't feel the way that I used to and I go home with more energy and happier to be with the family. I have it on on half power all day while I work. I can't believe this light works! This is my first product of this type. It is great!"  


"I don't usually leave reviews, but this device is the best thing that's happened to me in years. I didn't realize the extent of my SAD until I got the light therapy unit. I even bought one for my brother. Even he raves about it. It's convenient and does the job. I thought it was all hog wash until I tried it. Best thing I have ever done for myself."

  "I really appreciate your quick response, the best example of customer service and appreciation I have ever encountered. I have used the unit for a little over one week now and I like it immensely. Has a very positive effect and does not take up any space compared to the larger light therapy units. I am an University Professor and I simply love the unit. I gave the empty box to my psychologist. He thought it was a great product and was very impressed with the price. He is going to recommend it to many of his clients. Again, my sincere thanks."  


"The light works wonderfully and I find the mechanism designed to attach the light to lap tops quite ingenious. I have told several people about your lamp as I have found it to be very effective and easier to use than the table top SAD lamps I have been using. My daughter ordered one and I am praying it will work for her as well as it has worked for me."

The light is effective, light and portable. It worked perfectly for my time in Alaska. It took about 5 days before I noticed the effect, but after that I could really tell the difference.

  "What a great product! I have owned the Syrcadian Blue Light Therapy device for about a year now. It is easy to use, attractive, and quite effective in elevating my mood. The buying process was quick, and convenient. I would highly recommend the Syrcadian Blue to all. Great Product!!"

Love your light! If you have noticed a spike in sales in the Seattle area, the Milwaukee, WI area and Whitehorse, Yukon, it's because I have recommended this light to about 30 friends and family, and several have bought one! The word-of-mouth effect is strong with this product.
  After using the blue light for a few weeks now I can say that it does make a difference for me. I'm not sure if it is physical or psychological, but either way I feel a sharper. I have also placed one at my wife's desk and believe that she to has benefited. My co-workers are asking to test it the next winter season.

  "Winter blahs affects everyone whether they realize it or not and it affects every area of your life. Your "happy light" is what keeps me smilling while others are cranky and moody. It took me a long time to buy a light because I just couldn't find what I was looking for. Many looked cheaply made, or they were huge or the prices were sky high. Finding this compact light that LIVES on my laptop is perfect, compact out of the way and there every morning when I check email, do banking or go on facebook. I will definetly spread the word about your amazing product."


"I LOVE your product! I started looking for a seasonal affect solution a decade ago, and the best I could come up with was a 1 by 2 foot monstrosity with 4 giant lightbulbs and a hand-crank. What a pleasure it was to find Syrcadian Blue. It is small and compact and optimized for the proper light tone. It easily sits on my laptop, doesn't interfere with my work, and leaves me feeling refreshed and energized. I recommend this product highly, and I don't say that lightly."

"We work in an area that doesn't get a great deal of natural light. I sit in front of a computer for at least 90 minutes per day and find your light very helpful. It took me a bit to get used to, but now I barely notice (if at all) that it is there. It has already made a difference. I am sleeping more soundly and more rested when I wake up! I have sent information to at least 6 people about the light. I hope it helps them as much as it has helped me."


We bought your Syrcadian Blue light on Amazon. It works great! While traveling one of the clips broke (I broke it, not a defect) and I was told you would send me new clips. Wow, imagine my surprise when I received not only the new clips but a complimentary car accesory kit. I am so overwhelmed and thrilled. I love my light and now I can plug it in my van as well as on my computer, this will be of great benefit to me. Many thanks and appreciation at such a nice gestrure. I will definetly spread the word about your amazing product.

  "I can't say enough good things about this light. I've suffered from seasonal depression since my early teens. I've taken anti-depressants to help combat it, but they have not been as effective as I would have liked. After two weeks of using the light only at work, not only am I more "awake" early in the morning, but I'm better able to concentrate while working. An unexpected side effect is that I'm also sleeping better as well. I initially purchased one of these for my monitor at work and after I found how well it worked, purchased one for my home monitor and another for my car. While I think they are a little expensive, I obviously thought the expense was worth it by purchasing the two others.  


It works for me. A great way to get the desired light while working at my computer. Easier to use than other lights I have tried. Easy to set up. The attachment mechanism to secure the light to the monitor could be more robust, but it generally stays where I put it. More importantly, the light had the desired effects on my energy. After 3 days I was nearly back to the energy level where I am in the summer. After a week I was back to 100%.

"I really like this product. I especially notice how much better I feel on cloudy and rainy days. Everyone at the office keeps asking me why I am always in such a good mood. I have bought two more of them for friends and they are now true believers as well."


"At first I did not think this unit would work, but my wife bought it for me and I tried it on my laptop. Now I won't go without it. I use it every day on the lower dose setting and I can use the light all day long and and it does not bother me at all with my work."

"I am retired software engineer and use my computer a lot during the day. I am not a gadget guy, but I bought the unit because my doctor recommended it and your device fit my lifestyle better than a panel. The science is a little over my head, but it certainly works. Now I can't seem to stay up late, but I do sleep much better than before."


"I am really surprised at how well this works. My doctor told me to consider light therapy to help with winter anxiety, but I did not think it would work that well. But the cost was much lower than other units so I tried it. The results were not immediate, but they have been pretty amazing. Now I have one on my laptop and one in my car."

"As a salesperson I spend a lot of time in my car, and I decided to try your light since my doctor said that it might be a good therapy for me. I do not have the time to sit in front of a light panel every day, so I tried the car adapter. The unit is too bright when it is really dark outside, even on the lowest setting. But it is fine when it is not too dark. I really feel better and now I want one for my husband's car."


"I bought this unit for my wife and she did not want to use it but I put it on our downstairs computer since she uses that computer a lot. Once she got used to it she really likes the way it makes her feel. And I can honestly say that I can notice a real difference in the way she feels. Her biggest complaint is that she now falls asleep every night at 10PM, but she sleeps much better and wakes refreshed.

  "I got my Syrcadian Blue last spring and started using it right away. I work at home and my office can get pretty dark and dreary on cloudy, rainy spring days and pretty much all the time during the winter. After only a few weeks of using my "happy light" as I like to call it, I noticed that my moods didn't seem to fluctuate with the weather. So, until I move my office to Hawaii, I will be using my Syrcadian Blue light routinely. In fact, I have been so excited about my "happy light" that I got one for my wife and one for my father and I am anxious to see how they like it."   "We just moved to a new office and it has no windows. Everyone has been complaining about how depressing it is. One of my girlfriends told me about your light, and so I bought one and put in on top of my computer. I already love it and can't believe how much better I feel after a long day in the "dungeon". I have more energy and I was even singing on the way home two days ago! There are more than 300 people in this office and many of them have stopped by to ask me about my light. I have given them your link and hope that it helps!"

"After using my new light for about a week I started to notice a real difference. At first I did not really notice it too much, but then I found myself more relaxed and I just have a much better attitude. I really noticed it when I quit using it for a few cloudy days, and that is when I could compare how much better I really felt."


"My husband bought me this light and I was a little leery to try it (and wondered what his motive was!) But I do suffer from a bit of depression in the winter, and so I gave it a try. I was amazed at how well it worked. I find that I do not need it in the summer, but from about November to March it is a real godsend."
