Feit for one makes a -40 LED bulb. Feit

Actually it's the electronics that drive the LED that get the temp spec. Personally I'd try what's available and see if it worked unless it was a PITA if it didn't. Components and circuits are spec'd at guaranteed, not typical.


Actually, I'm pushing the temperature limit on the high end by experimenting with them in fully enclosed fixtures, which is something many brands tell you not to do. In the worst case I've burned out two LED bulbs with less total hours on them than you would get from one conventional incandescent bulb. The current bulb is rated for 120° F, but I expect it's engineered with some headroom, so maybe 130° F. We'll see...
