So I picked up two ZooMed basking bulbs today from the pet store, I screwed them in, then went out to eat. 4 hours later I come home and the bulb is very dark and is already gone out. I've had a problem with ZooMed bulbs in the past but.. 4 hours?! Really?? & I know it's not my fixure, I have a Fluker's 250ww that works fine. I plan on filing a complaint to zoomed. Any one else had these problems?
