A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. The output from an LED can range from red (at a wavelength of approximately 700 nanometers) to blue-violet (about 400 nanometers). Some LEDs emit infrared (IR) energy (830 nanometers or longer); such a device is known as an infrared-emitting diode (IRED). read less

LED (light-emitting diodes) that are just as bright as bulbs, last virtually forever, and use hardly any energy at all. An LED is a special type of diode (a type of electronic component that allows electricity to flow through in only one direction).
