(White OLED) Lighting made of organic LEDs. WOLEDs have the potential of obsoleting both incandescent and fluorescent bulbs while providing extraordinary flexibility in the design of lamps and lights. An incandescent bulb emits from 10 to 15 lumens per watt; fluorescent from 40 to 90 lumens. However, in 2014, Cree was the first company to achieve 300 lumens per watt in a white, high-power LED bulb. See LED bulb and OLED.
