I will never order me again this lamp because with an average shelf life of six months to max. a year of price is clearly too high. At least one of the two light sanding is after about 6 months on the mind and dark deposits appear. The only light in the room is too dark anyway, but as an eye catcher I found them always great - unfortunately the quality is good nothing ...... And there is no warranty on lamps, one has finally scared me as a customer.
