I agree with the other reviewers that the lamp is made very cheaply and durability is questionable, but it does have a 3yr. warranty. I was fortunate to buy one when there was a promotion, so basically BOGOF and for that reason kept it at a 5 star rating. If I'd paid $90 a piece, then I would rate it a 3. As for the light, I was amazed at how bright and white it was at the high setting, which I like for my office while working on the computer. I placed the other one on my nightstand and use the lower setting. It's perfect for reading and really seems to give my BR a calming ambience. I haven't used them long enough to determine if it will help w/ the winter blues, but think it might. Also one of its best features is flicker-free illumination without generating EMFs. For those of you that use feng shui, this is very important.
