Philips introduces 75W equivalent LED light

Philips claims that the new lamp will create light that will be indistinguishable from a standard incandescent light bulb.

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 and limited brightness. LED lamps have only been able to emit light equivalent to a 60-watt standard bulb.

On Friday, Philips will look to change that game by 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, Massachusetts consumers will save $300 in electricity costs alone and will break even in 1.6 years.
"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.
