I’m trying to pick some LED light bulbs for outdoor use. I live in Canada and we can get temperatures below -40°C. On all the bulbs I look at, there is the disclaimer:
Minimum starting temperature -25°C (-13°F).
What does this mean? Will the bulbs not work reliably below this temperature? I’ve tried searching the internet and everybody (albeit of indeterminate knowledge) is saying that LEDs will actually work better at cold temperature.
For what it’s worth, I did come across one bulb labelled “COLDSTART” and “-40°F” but, unfortunately, it is not as bright as I would like.
