I have 3 outside CFLs working here and temps often are -40C. No  
trouble at all. I don't know what breed they are. And lot in use in  
the house. No RFI problems as far as I can tell.

Some years ago, I was living on a mountainside ranch at 1500ft ASL near
Santa Rosa CA and while it wasn't routinely as cold as Michigan in  
it got below freezing.  I'd put a CFL in the main house's (unheated)
laundry room and after a couple of months it started generating S9++  
on all the HF bands. W1RFI asked if I could send it to him but I was  
and had already disposed of it.. Now I am in Michigan I have CFL's for  
my outdoor lamps and they are not (yet) acting up at all.  A 3-month-old
Sylvania in my hallway went pzzzztt! and arced over, base to lamp, in
December, but it had been RF quiet before.   Don't ask about the track
lightning's SMPS.
