The light-emitting diode (LED) is today’s most energy-efficient and rapidly developing lighting technology. Compared to fluorescent lamps, LEDs use only about half the electricity to produce the same amount of light. Quality LEDs last longer, are less prone to breakage, and offer comparable or better light quality than other types of lighting. LED lamps and retrofit kits are often compatible with existing light fixtures with no need to rewire or replace fixtures, and LED products are available for most lighting applications.
