Besides the electrolytic and bulb, the starter cap is very failure-prone.


FWIW, of the modest pile of CFLs I autopsied from my own house, 100%
of the failures were from failed heaters.

This may be atypical. I get good service from CFLs running them
without enclosures; the enclosed, base-up fail modes may be different.

And frequent cycling on/off is the major failure mechanism of the heaters,
IMHO. I get very good life from CFL's in constant-on service. The Bright
Effects lamps from Lowe's have been very good, and are priced fairly.
