An organic light-emitting diode (OLED) with the potential to produce the same quality of white light as incandescent bulbs, but with power efficiencies much better than even fluorescent lighting, has been developed at the Institute for Applied Photophysics, in Dresden, Germany.

The OLED exhibits efficiencies of 90 lumens per watt and shows potential to go up to 124 lumens per watt, compared to 10 to 17 lumens per watt for incandescent bulbs and 60 to 70 lumens per watt for fluorescent lighting.
