My guess is it's the enclosed "upside down" they don't like. CFLs can
run hot, they are not designed to run upside down and enclosing them is

This one doesn't make sense. I have multiple bulbs outdoors, and in the
winter they work fine. When it's really cold (< -20C) they may take a
minute or two to reach full brightness, but aside from that they always
As a solution to your problems, first thing I'd do is buy a Phillips
Marathon CFL. While they are a little more expensive, they are the best
performing ones I've used. Generally, they start up REALLY quickly
(usually indistinguishable from an incandescent), reach full brightness
very quickly, and so far I haven't had one fail.
OTOH cheaper brands have many issues. They either start up slowly,
and/or take a long time to get to full brightness, even when warm. I
have had a few of those fail, in each case they were replaced with a
Phillips bulb and since then no failures.
