Philips GoLite BLU Energy Light Therapy Lamp, Rechargeable (HF3429/60)

Purchased about a month ago and wanted to give it some time before reviewing. There are "warnings" regarding possible side effects when starting use with this as with many things. I always assume I will not be one of the people experiencing them because I go into whatever with a very positive attitude. I use this Mon-Fri (as long as I remember) at work. I am in an office with no direct outside light and because I do a lot of design work, I do not have the office overhead light on but rather use a combination of three lamps--in other words, a more moderate light situation than most offices with the glaring flouresants. Although the lighting has been much easier on my eyes, I also began experiencing issues with my sleep patterns and suspected the low light was adding to the problem.So first week, I was shocked I did experience side-effects. I was on the lowest setting but I still felt a little light-headed and kind of queasy. Since I knew it was a possibility and that the manufacturer advised it would go away after the first week or so, I pressed through. Second week, not as bad and third week negative side effects gone. AND the addition of some very positive ones. This was all a part of me getting more aware and proactive about my sleep so about the same time I got this I added Twilight (for Android) to my G-2 phone and F.lux to my laptop.The combined effect has been wonderful. I now get sleepy earlier at night helping me get into bed in time for 8 hours and still up early (6-6:30) to utilize my most productive time of day-morning.My sleep has been better and I am ready to be awake earlier. Throughout the day my energy level is much better. Last fall, after about 6 months working in this low light environment, I began to have a serious lack of energy. Arriving home at night fixing a meal was about all the energy I had. In the past weeks this has been steadily changing. This past Saturday I was active from rising to bedtime and only felt the natural need to rest not the exhausted feeling I've had. So while purchasing and using this has combined with some other steps I have taken, I believe this little blue light gets the lion's share of the credit for what I believe is just the beginning of a much healthier me.As for product details, it's compact, light-weight and easy to use. The battery is a nice feature allowing for placement without being limited to the nearest plug. I have yet to go beyond the second level of light (there are four). When I first turn it on, it does "smack you in the face," but I do as instructed and have an overhead light on as well. Once I get it positioned I am aware of it at first, then I "forget" it ... to the end I am usually going for 20 minutes a side (you place it so it shines on the side of your face) and will all of a sudden "remember" it, look over and I'm already into 30 or sometimes 40 minutes on that one side.Yep, I am very happy with my purchase and glad I added this to my wellness items.

I felt like the light therapy itself actually helped me out. Maybe it is placebo effect, but I'm all for it if it makes life better for anyone.I used it. I took it to work with me. I seemed to notice a difference in my mood and energy levels particularly in the middle of the day when I normally felt a slump. I did not experience headaches or have any other problems with it like some users.The problem I DO have with it is that it doesn't hold a charge. I couldn't find anything about how long a charge was supposed to last, but I left it plugged it overnight and turned it on this morning only to have it run out of juice after less than an hour. I realize I'm only supposed to use it for 20-30 minutes a day but it seems a little silly for something to be labeled as portable that can only be used twice before needed a charge and I just can't give it more stars because of that.UPDATE 1/20/2016: After using the light for a few weeks, I definitely noticed my energy increased. Perhaps having a light shining in my face for 30 minutes every morning woke me up faster, but I felt more alert earlier in the day than usual. I also noticed that I didn't feel like I needed some caffeine around 3:00 pm like I usually do. After using the light for a few weeks, I just kind of stopped because I'm terrible at consistency. One thing I noticed when I stopped using the light was that my need for a pick-me-up coffee around 3 pm returned. I have also noticed that I can't use this after noon because I'll have trouble sleeping at night.Overall, I think it helped with my sad... at least the fatigue part. It is still cold and dreary where I live, but I'm not struggling as hard this year as I have in years past. At the very least, it has improved my mood and energy. To date, I have no experienced any headaches and the unit is still performing as expected. I am changing my review from 3 stars to 4 stars because while I'm still displeased with use time, I'm very happy with the overall effect it has had on me.

bought the product more than a year ago to help reset my circadian rhythm. I am used to sleeping only by around 2AM. Because of my job, I had to get used to a new routine of waking up by 6. I use the product for 15-20 mins each morning as soon as I woke up. Definitely helped me wake up early and sleep on time too. Stopped using it for a while and went back to my old lifestyle. Started using it again just 2 weeks ago and its helping me get back into waking up early. good battery life, portable.
