I had the Powersun bulb that was about a year old burn out about 6 weeks ago. I got a replacement from local store and that one burnt out in a few days. I returned it and got a replacement, then that one also burned out.
I changed the fixture, and the next one burned out.
I have not had a standard ceramic fixture nor one that hangs from above. I've used a clamped work light with the bulb tilted at an angle without a problem.
Now it seems I do have a problem, so I did purchased a Repti-Zoo 8.5" 200 W max reflecting dome and placed a hook for it to be suspended. New bulb that I recently purchased off of Amazon. That has also burnt out within a few days.
I am not sure why they are burning out when before they were not. Thoughts?
