Lighting maker Osram is introducing its first white-light products using OLEDs. Though not as efficient as compact fluorescent bulbs or inorganic light-emitting diodes, the eight-centimeter round panel gives a diffuse glow and a true white that’s comparable to that of incandescent bulbs. The appearance of its white doesn’t change at different dimming levels, a problem with some earlier prototypes. The product is meant for places like museums and hotels; it’s a bit costly for home use.
