I have had 2 floor model Ott lights and the first only lasted 89 days and the second lasted less than a year. I will not buy another although I did really like them when they worked. I currently have a floor lamp I purchased at Home Depot and put a daylight florescent bulb in. It works fairly well, but I did prefer the light that the Ott emitted. Just could not justify the cost with the limited duration of the light.
