Roland Piquepaille writes: "You all know that incandescent light bulbs are terribly inefficient, turning only 5% of the electricity it consumes into light. Fluorescent lamps are better using up to 25% of its energy as light. And solid state lighting devices lose only 50% of the energy they received. But now, researchers at Arizona State University (ASU) claim they've developed organic lighting devices which are 100% efficient. The researchers think it's possible to produce these solid-state lighting devices based on OLED technology at low cost. If this is true, this would be of major benefit to the environment by conserving energy and natural resources. Read more for additional references about these future lighting devices."
