LED lamps are expected to revolutionize the lighting industry because of their sharply reduced power consumption and their long life compared with standard incandescents. But to date, market acceptance has been slow given the high initial cost ($50 and up in many cases) and limited brightness. LED lamps have only been able to emit light equivalent to a 60-watt standard bulb.
Now Philips is looking to change that game, announcing that it will market an LED lamp later this year whose light output equals that of a 75-watt incandescent.
The bulb, the EnduraLED A21, will retail for about $40, last 25,000 hours and produce 1100 lumens of light by consuming just 17 watts of electricity. (A standard 75-watt lampfrom GE produces 1170 lumens.) Over the life of the lamp, consumers will save $160, the company says.
While 75-watt equivalent LED lamps have been available in PAR sizes (the types of reflector lamps typically placed in recessed ceiling fixtures), Philips says its EnduraLED is the first 75-watt equivalent in a standard “A” lamp shape. The company expects it to earn the government’s Energy Star rating prior to release.
“The trick with an A lamp is how to project 1100 lumens in 360 degrees,” said Ed Crawford, general manager of lamps for Philips Lighting, North America. “It’s absolutely more difficult to do 1100 lumens in an omni-directional lamp.”
To accomplish that, the new lamp, available around September or October, contains 18 LED modules fixed in multiple directions. Various metal fins surrounding the lamp are used to dissipate heat.
Unlike low-wattage compact fluorescents, which often produce light of a very harsh color, the new lamp will create light that will be indistinguishable from a standard incandescent, Mr. Crawford says.
According to Philips, some 90 million 75-watt incandescent light bulbs are sold annually in the United States, making it the second most popular wattage bulb after the 60 watt (425 million per year).
While it’s definitely wishful thinking on the company’s part, it says that the nation’s energy use would be cut by 5,220 megawatts if if everyone switched to one of Philips’ new lamps.
