LED lights can be a great gift to the holiday decorator. Even though they cost more than other types, they last longer, produce far less heat and use less energy.
The letters stand for “light-emitting diode” (but if you’re like some of my neighbors, they might more appropriately stand for “love elaborate displays.”) Unlike incandescent bulbs, LEDs are solid-state. There’s no filament that heats up with wasteful thermal radiation. Instead, light is released when electrical current excites electrons in the diode.
