Technology in the field of LED (Light Emitting Diode) has exploded. They come in a wide variety of lamps and styles, becoming more affordable and available.
Warrantied for 10 years and decreasing consumption by nearly 75%, LED lighting gives the same light output and are interchangeable with any bulb.
The efficiency of conversion from electric power to light is generally higher than with incandescent lamps. Since the light output of many types of light-emitting diodes is small compared to incandescent and compact fluorescent lamps, in most applications multiple diodes are assembled.
Diodes use direct current (DC) electrical power. To use them from standard AC power, they are operated with internal or external rectifier circuits that provide a regulated current output at low voltage. LEDs are degraded or damaged by operating at high temperatures. LED lamps typically include heat dissipation elements such as heat sinks and cooling fins.
