I've got a hanging light fixture in which I can't get CFL bulbs to
work. They work fine screwed upside down in my garage light sockets,
the bulb is confirmed working in other lamps.

Standard bulbs work fine in this same hanging fixture. Any theories as
to why the CFL bulbs don't want to work in it?
Be careful with upside down CFLs and in particular CFLs mounted in
fixtures upside down. Most don't like this orientation and being
enclosed in fixtures makes the problem worse. The circuits in the
"base" overheat and this *drastically* reduces longevity.

Not in my experience. Almost every single light fixture we have is a
flood, so the CFLs are all mounted upside down and in an enclosed
fixture. I have yet to replace a bulb and they're all at least 6 years
old.
Perhaps your fixtures are vented letting heat escape?

Nope.
