Re: Why do fluorescent Bulbs (CFL) last only a few months?
There was a blog article in one of the EE trade rags (Electronic Design, EDN, EETimes?) not too long ago about this subject.
One of the things that's often overlooked is that most consumer-grade CFL units are made to be burned base-down. The electronics produce quite a bit of heat and burning in the inverted position just aggravates matters. Burn one in an inverted recessed can fixture and things get even worse.
Duty cycle and low-temp operation, as others have mentioned, are also major life factors.
