I've never had a CFL failure that I could trace to the CFL.
It's always the electronics driving it. A power glitch can take
out a LED just as easily as a CFL.

I've had a couple CFLs burn out at the bulb from old age. Most had
electronic failures, or jsut broke.

The longest lasting CFL may be one in my bathroom with 10 years of
on-off use. I'd have to remove it to checked the purchase date I write on
them though.

I've had a few CFL's fail due to electronics failure, but the newer
bulbs last longer. Unfortunately as they age they get dimmer. Looking
at an aged bulb I noticed that the phosphor layer has turned a brownish
color.

I'd have to agree that the newer ones seem a bit better. They've figured
out how make them as simple as possible now is my guess.

I did have one failure that when I took it apart, 1 of the wires to to
the flourescent was disconnected & the others were questionable.
Soldered them all & re-assembled the bulb and it's still in use in the
basement bathroom.

they're still useless for outdoor cold use. The ones outside by the stairs
are like nightlights when the temps drop to freezing. It's amazing they
even start.

I'm not a fan of the warm up period they take, even indoors.
