LED stands for light-emitting diodes. Each LED light bulb consists of several small light sources that illuminate when electrons (a.k.a. electric currents) move through a semiconductor material. LEDs provide solid-state lighting, meaning they emit light in a specific direction instead of in all directions like CFLs or incandescents.
Because LEDs are a rapidly changing technology, it can be challenging to select the right one for your home. Fortunately, your energy provider has preselected high-performing, ENERGY STAR®-qualified LEDs. Not only does this make your shopping easy, but it also helps you use 75 percent less energy.
