Ditto - that's the great part about solid state devices. They're pretty impervious to most conditions. I've even switched my outdoor (stick) house lights to LED. And we too get temps to -30F (-35C) pretty routinely. Outside house, boat trailer, RV - all have LED's, without any issue....
I had a couple of times years ago, where traditional bulbs shattered on startup outside (very cold glass with a hot filament inside). And fluorescents just won't even flicker when they get too cold. But LED's always just work.
