- Cree leads the LED lighting revolution and is making energy-wasting traditional lighting technologies obsolete through the use of energy-efficient, environmentally friendly LED lighting. Cree first brought the blue LED to market in 1989, and today Cree's XLamp® LEDs have continually exceeded industry standards for brightness and efficiency. Indeed, XLamp LEDs were the first "lighting-class" LEDs – LEDS bright enough to be used in general-illumination applications, such as desk lamps, ceiling fixtures and street lights. In addition, Cree's extensive line of high-brightness LEDs are also introducing new performance levels to outdoor video displays and decorative lighting.
