Light therapy is growing, and there are no wrong model currently on the market. Big, small, white light, blue light .... what to choose? So I had the opportunity to test this model blue light. Sincerely, do not particularly suffer from lack of light, or currently winter blues (hope it lasts !!!), I have not had the opportunity to test a better on my good mood the last 15 days. (A tomorrow unless my boss tells me that I will not have my year end bonus !!!) However one thing is certain, this device gives a very pleasant impression of a window on a beautiful blue sky. Missing only the cicadas. Indeed, on the desk (no risk to the eyes, but avoid to have facing you), it instantly brings a very valuable benefit. And we will not be fooled by its size: its light output is inversely proportional to its size. The goal is ... recharge our battery clean by a contribution of light (UV-free) and we really feel that the sun is at hand. So much so that we begrudge a little off .... It is Philips: So nice finish, good build quality and perfectly packaged. Although modest in size (14cm on 14cm, 3.5 cm thick ... it reminds me of the bygone era of CD players ... nostalgia when you hold us !!!)), the Energy Up has a light output more than enough (I never use it at max power) The big advantage is its portability. Rechargeable battery (about 3 hours of battery life: with one half hour per day recommended), size, ease of use (5 degrees of light intensity, timer for every 10 minutes in the form of 6 LEDs), removable foot and neoprene cover provided allow to take him anywhere. Ideal on a corner of the office. While white ?, blue lamp lamp? .... For you to see and test. I am in any case convinced that this unit can provide better during those periods when the brightness is sorely lacking ... this little window on the azure blue can only be beneficial. Besides, my office neighbor borrows regularly from me, so much so that I sometimes struggle to get my Energy .... Up Remains a low price ...
