LED Christmas LightsLEDs are constructed from tiny solid-state chips similar to those used in computers. These chips directly convert electricity to light without the use of a filament or glass bulb. Instead the chips are encapsulated in solid plastic that can be made into a variety of shapes and sizes. Since LED's have no filament, there is nothing to burn out and no need for a breakable bulb. Without the burning filament, very little heat is produced.
