On non-LED globes, cold weather can be quite a problem but LED globes do not produce much heat so they can handle massive changes in temperature much better. 

Not only can LED globes handle cold very well, but they can even handle extremely low temperatures as well. So they are perfect for areas with very low temperatures.

Just to explain why LED works so much better than older globes, the reason is that incandescent globes work by heating a filament which becomes so hot it glows and hence emits light. Less than 10 per cent of the energy used actually get converted to light, the rest is heat. 

LEDs convert up to 90 percent of the energy into light, and also they have a heat sink which takes away the heat. 

In fact it is too much heat that will destroy an LED - but they work extremely well in cold temperature, so very cold areas are ideal for LEDs.

That's correct: LEDs will start failing in extreme heat but thrive on cold!

I live in a snowy environment and have lots of outdoor LEDs, have never had any problems, so I would say that LEDs are perfect for cold outdoors.

Cold air help keep the LED cooler, which it needs to operate correctly, so it will actually help it along.
