LED Holiday Light illustrate: LED Christmas lights use LEDs instead of traditional miniature incandescent bulbs. LEDs are much like incandescent bulbs, except that they have no filament inside to burn and take away the entire bulb. Instead, they are illuminated by electron motion in the semiconductor material. Another benefit of this source is that there is not much heat and wasted power.
LEDs have been around for a long time, but they have only been used as Christmas lights in recent years. One reason is that the old LEDs were originally only red. On the other hand, incandescent bulbs only emit white light, but are wrapped in stained glass. Another problem is the lack of brightness of the LED. However, the potential is there, and advanced LEDs solve these problems. Today you can find LED Christmas lights of various shapes and sizes. They can flash like regular incandescent lamps and come in a variety of colors to choose from.
