New York Times : A new LED is being developed for sale later this year that will be comparable to a 75-watt incandescent bulb in brightness, yet it will use less power and last longer. To date, LEDs have had limited appeal for consumers because of their limited brightness and high initial cost. According to Philips Lighting, its EnduraLED A21 will cost about $40, last 25 000 hours, produce 1100 lumens of light, and consume just 17 watts of electricity. Although 75-watt-equivalent LED lamps have been available in PAR sizes (for recessed ceiling fixtures), Philips says its EnduraLED is the first 75-watt equivalent in a standard “A” lamp shape, writes Eric Taub for the New York Times.
