Well, I don't know much about the details, but we've gradually been replacing with LEDs for several years now, and I have yet to replace one of them. Most of them are in ceiling/wall fixtures with wiring and all that from the 70's.
The one on the porch is relatively new (only since last summer, when we replaced the whole fixture) but I haven't noticed temperatures affecting it and we've had a couple cold snaps this winter.
I said, way back when, the market would probably eventually kill the incandescent light bulb, as well as others, so I didn't see the point in the government getting involved. At this point, I'm not even sure it really matters.
Now, gas cans, OTOH... Please, for the love of all that's holy, PLEASE, make gas cans GREAT again.
