This is a good point. One concern about LED landscape lighting is that the low heat it creates may be an issue in cold climates that receive a lot of snow. This is because standard incandescent fixtures create so much heat that snow will not accumulate on the fixture. LEDs do produce some heat and it is sufficient to melt light snowfalls; however, a heavy snowfall will accumulate on a poorly designed LED outdoor lighting fixture if it is not properly designed. If you plan to use LED landscape lights in a northern climate it is critical that you select a fixture that is designed to deflect snow. This can be accomplished by utilizing a fixture that has a steep pitch cover or is otherwise designed to direct and manage heat in a manner to eliminate snow accumulation.
