Re: Compact Fluorescent light bulbs burning out

I have noticed the same thing. What I beleive is happening is that the bulb is inverted at an angle and that allows heat to collect inside the glass globe and around the base of the CFL where the electronics are located. I am sure it is a heat problem because I installed one of these lamps in an inverted reading lamp and it went out after 10 minutes. It would come back on again, suggesting a thermal runaway type failure.

I have a ceiling lamp/fan combo in which lightbulbs are constantly
burning out. My dad was convinced it was in my head. I'd already
tried regular bulbs and other fluorescent, I hadn't tracked it but
they were dying far too frequently. This spring, on a bet with my
dad, I swapped the 3 bulbs for brand new Compact Fluorescent lights.
6 months later, 2 of them are dead. One died 2 months or so ago. I
left it in there because I was seeing if maybe having 3 bulbs was too
much for the lamp. The other died today. This is the office, the
light gets turned on and stays on, often for several hrs at a time,
never just for a few minutes.

This lamp just kills lightbulbs. Not just CF bulbs, either, I'd even
tried regular bulbs, they lasted even less time.

The only reason I could find as per google was a possible
overvoltage. But I haven't had the problem on any of the other lights
in my house, so it's not a "global" issue.

The big question is.. is it the lamp, or is it a electrical problem?
I kinda like the lamp but obviously if its a problem, it's got to
go.

Suggestions/tips welcomed!
