For this to work, there must be greater than 2500 lux lamp (here was the 10000lux 10cm distance) minimum, a theoretical exposure of at least 2 hours per day (the instructions recommend less than that) ...
This lamp seems well designed respecting the indications for the therapy! 10000lux light and close to the characteristics of natural light. Easy to implement: I go out of the box, I connect, I pressed ON, I expose myself ... and that's it!
After a few phone calls to psychiatrists and psychologists hospital colleagues, it turns out that 10,000 lux at 10 cm is not good for the eyes, and it would require you to have the almost pressed against your face lamp (lololol) ... It would be best to put it on the side between 30 and 45 ° for not éblourir you or hinder you in ... max 30-40cm from your face ... for 2 hours a day (if you're prone to winter depression, do that for 15 days or even throughout the winter ...) ...
I can not tell you if it actually does affect me for the morale of course (one is in September and there is the sun) but for my sleeping problems (my sleep cycles slowly slide ...) 7d m 'helped to mitigate ...
PROBLEM: 7d after use has 2 hours a day ... POOF about nothing! neon goes out, I try to turn it back on, it emits a flash by pressing the ON / OFF ... 3-4 times ... then nothing!
In short: not very expensive, minimum power to go ... If you suffer from seasonal depression, declining morale in winter and autumn, struggling to feel the morning of attack: you can use it for breakfast or working in the office, you will find it helps !!
... Remains to know the cost of changing neon now! Manufacturing problem for this unit or reliability problem on the line: I do not know ... but I am extremely disappointed!
