Re: Compact Fluorescent light bulbs burning out

quoting:
I have a ceilinglamp/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 otherfluorescent, 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 CompactFluorescentlights.
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 thelamp. 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.

Thislampjust 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 thelamp, or is it a electrical problem?
I kinda like thelampbut obviously if its a problem, it's got to
go.

Suggestions/tips welcomed!

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 readinglampand it went out after 10 minutes. It
would come back on again, suggesting a thermal runaway type failure.


If it is heat, try commercial grade cfl, like Panasonic GEN IV. They
are built to withtand heat from being in completly enclosed fixtures.

But with the incandescent bulbs, it's probably the odd angle they are
at in the fan, with the fact that most GE and Sylvania bulbs don't
even have filament supports and that odd angle means the filament
stretches out of shape in strange ways But, I have had early burn
outs with bulbs with filament supports simply due to bad quality.
