When you buy an Ott light - it's a coin toss if it's a good one or not. I had one go out and it was a fuse thing. I did write to them asking for assistance and was told to get an electrician. Ummm - No. For that kind of money I can buy something else. I went to IKEA and bought a floor lamp for $20.00 that works as well as the Ott. So as my Ott lights die - I have 3 more - they will be replaced with another brand. Somewhere I do have a bulb that came with one of the lamps. Just not sure where it is before the others go.
