I haven't tried the new LED's in the cold yet.Semi-Ret Electrician said:I know of a bunch that have been burning for several years in a -40 F freezer. They came from Home Depot but were installed warm and never turned off.
I have been burning the halogens here the past few years and like them. I haven't had one burn out yet.99cents said:Stock up on incandescent A19's. When they run out, buy halogen A19's. I have even seen LED's underperform in cold weather.
temperature around here is near zero and some arent even starting. Most just warm up but remain dim.I use whatever is cheap and they start, just takes a while to warm up.
These are in post lights and exterior security lights.I know of a bunch that have been burning for several years in a -40 F freezer.

Yes that might work but for us to start selling them they would have to be listed.You mean a vari resistor?
Theres used to be little "buttons" sold that you put in the bottom of the lampholder before you install the bulb that did just that. They looked like the flasher buttons, but they were a resistor type of thing.Yes that might work but for us to start selling them they would have to be listed.
The ones I've seen were wire into TV's to enable de-gaussing at start-up.
It would be hard wired into incandescent type circuits to lower the run voltage from 120V to say 110V (and soften the surge) which would greatly extend lamp life, at the expense of lumens, of course.
It would be like running a 130V lamp at 120V. They're starting to get scarce and pricey.
