Light Emitting Diodes (LEDs), “semiconductors that emit light when zapped with [positive polarity] electricity,” are on the verge of taking over the commercial and consumer sectors of the lighting industry. With greater efficiency, longer useful lives, and their “clean” nature, LEDs are the future of light, pushing traditional incandescent and fluorescent bulbs toward extinction. Only the higher production costs for LEDs have extended the existence of traditional bulbs.
