A typical LED light puts off about 40% of its input wattage in heat. Instead of projecting it forward from the light source like an incandescent does, the LED generates its heat at the back end.

So to say that LED streetlights can't melt snow is a misnomer. If the heat from the LED's was used properly they would have no problem melting snow.

The problem is though, what do you do to design a system to force the waste heat from the rear of the LED fixture to the front to aid in snow clearing? Even then, how much of the waste heat could such a system be expected to recover? :huh:
