Lighting: Light Emitting Diodes (LEDs)

What is LED lighting?

An LED is a microchip that emits light. Compared to incandescent lights that produce light by heating a tungsten filament, or fluorescent lights that pass electricity through a tube of ionized gas, LEDs are basically computer semiconductors that illuminate with the movement of electrons.

An LED is a microchip that emits light. LED technology offers many attractive benefits, including low power consumption (LEDs use at least 75 percent less energy than incandescent lighting), high output, long life, compact size, instant on/off, and reliable operation in cold temperatures. LEDs can last 50 times as long as incandescents and 10 times as long as CFLs. And unlike incandescents, which emit a lot of waste heat, LEDs don’t get particularly hot.

When will LEDs replace traditional lighting technologies and become the new standard?

While LED technology is quickly evolving into one of the most promising alternatives in energy-efficient lighting, widespread adoption will take time. The U.S. Department of Energy estimates that LED lighting will overtake incandescent and compact fluorescent technologies to become the lighting solution of choice in American homes within 10 years.
