The light-emitting diode (LED) is one of today's most energy-efficient and rapidly-developing lighting technologies. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting, according to the U.S. Department of Energy. LED lighting is very different from other lighting sources such as incandescent bulbs and CFLs. Key. LEDs are the size of a fleck of pepper, and a mix of red, green, and blue LEDs is typically used to make white light. LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and task lighting. LEDs emit very little heat.
