Bullshit..... I have CF's all over in Outside Sockets, and they work
just fine at TEMPS down below -20F....... Sir, you speak of things
which you seem to have NO Experience........

The CF's I have, are evidently way different than yours.
When it was about 0F outside, it would take about 3 minutes to come up to
useable brightness, starting out at a very dull glow. To the point that you
could barely tell they was on.
When it got down to -15 or so, and i had to turn it on, all I could see was
a dull glow close to one end, and I left it on. half an hour later, it still
just had just a dull glow.
That day, I went to the house, and got another brand of CF and put it in the
shed. When I was finished that day, i turned it off. The next day, I turned
it on, the exact same thing happened. that is when I just put an
incandescent back in, and said, to heck with it.
The only way I could get a light to stay working in those temps, is by
leaving it on. it would keep it's self warm. Once it cooled down, it didn't
generate enough lamp current, and heat to get it's self started on the way
back to a useful operating temperature.

I've heard that the problem at cold temps idsdue to not enough mercury vapour in
the tube. Apparently the really cheap CFLs often have a bit more mercury in
them since it makes the control circuitry simpler, so you may want to try one of
those.
I've had no trouble with CFL lamps outside at ~ 0C but it doesn't normally get
very much colder than that here.

Huh? It's been well under 0F for the last couple of weeks here, and all
three of my outdoor lights (_all_ standard CFs that say "not for outdoor
use") have been working just fine. Having never heard that cold temps were
a problem, I never even attempted to anything specifically intended for
cold weather use.
