I emailed them (OttLite) with my problem - light flashing before it appeared to burn out. Replaced bulb, no light. Tested circuits in the lamp - Switch works, power up to the lamp head, but no power between the two contacts where the bulb plugs in. That part is glued into the lamp head. They said take it to a qualified lamp repair shop, and they will sell the repairman the part. Somehow. I think that would be more expensive than buying a new one. The ballast is in the plug. That seemed to be working, since electricity was flowing from the plug to the switch, but the symptoms seemed to be a ballast going bad. Selling to repair shops is apparently an improvement. If you do a google search for "OttLite complaint" you see a lot of people reporting responses from the company saying to go to Joanns and buy a new one, or getting no response at all.
