This light lamp item equipped with a removable feet which allows vertical or horizontal orientation. It is an LED lamp that produces light at 10,000 lux. It's blinding. Daylight helps produce serotonin, the hormone of good mood. Used up to this lamp helps stop the production of melatonin, a hormone that pushes the body to fall asleep, she allows to wake up faster, and be in a good mood that day. Also ideal for a gift, after trying more than a week on this "therapy", I can say I feel good, there are no harmful side effects. For people in lack of sun, it is the ideal and safe because it is not a tanning lamp. (It should of course not spend time to fix the failing light to go blind :-()
