CFL Fixture Won't Work In Cold Weather


Three identical outdoor fixtures installed in September. All worked fine.
Cold weather arrived and one of them does not turn on, the others do.
When day (or night) is warmer, say, over 30F, the faulty one works again.
The bulbs are CFLs, but not the screw-base type. Instead, they have four prongs. Replacing bulb in faulty fixture does not remedy the problem.
Any idea as to what the problem is and what might be the solution?

All fluorescent bulbs don't start as well in cold temperatures. Slight manufacturing tolerances present in ballasts and bulbs even of the same makes and models may result in some fixtures never being able to start any bulb in cold temperatures.

When the fixtures comes on in not so cold weather, it may remain on through cold spells if you don't switch it off.

More Info On My Cold CFL Problem


The three lights are on a pair of three-way switches so that I can operate them from two locations. The one that does not work in the cold is very close to one of the switches. The second one (which does work) is very close to the other switch. Number 3, which does work, is the farthest away from either of the two switches.

You are right about it staying on, once it is on, even when the temperature drops. I did check it out that way when it started happening.
That leads me to believe, as one of you implied, that the starter may be the problem, not the bulb(s).

I guess I can either buy a new identical lamp and try that one, or swap the faulty lamp for a fourth one I have on the back deck, operating independently. Since I use the deck only in the warm seasons, the problem won't be an issue there in the winter.

Thanks for your input and suggestions. Maybe I'll hear some other ideas
here, so I won't do anything yet. Besides, it's too cold out there!
