One of the tubes in my 96W PC
broke (cracked through) right where the little blob of glue holds the tubes together in the middle. It was only 2 months old and vendors (I have since discovered) tend not to offer warranties on bulbs.
Before you ask, the bulb was on ~8 hours per day, over glass.
Has anyone else had this problem? If so, are there any manufacturers of 96W PCs that don't have this problem, or are there any online vendors who will offer a replacement if it does happen again?
