LIGHT-EMITTING DIODES (LEDs)
Solid-state lighting, including LED lighting, represents the newest advancement in illumination for both commercial and residential settings. LEDs are small semi-conductor chips through which current runs to emit light in a visible spectrum. LED lighting technology has been commonplace as indicator lights or display signage (usually red), but only recently has LED lighting been white enough or had enough light output to be practical as a light source. Today, you can find LED lighting equivalents for standard bulb shapes and PAR lamps, and in a range of lighting fixture types: recessed lighting fixtures, under-cabinet lighting fixtures and other accent lighting fixtures, wall sconces, kitchen lighting fixtures, bathroom lights, even ceiling fan light kits with LED lighting.
