Royal Philips Electronics announced a new light bulb that produces equal light as a 60-watt incandescent with the same energy use as a compact fluorescent but with a much longer life and mercury-free at the Lightfair International tradeshow in Las Vegas.

The new bulb features a cluster of LEDs, and produces 806 lumens of light using only 12 watts of energy, with a life of 25,000 hours, which means that a consumer could save $120 over the lifespan of the bulb simply by using it to replace a single incandescent bulb. This EnduraLED can be operated by motion sensor, is dimmable.

According to Philips, if all 60-watt incandescent light bulbs in the United States were replaced with this new bulb, energy use would decrease by 32.6 terawatt-hours per year, enough to meet the lighting needs of 16.7 million households. Therefore, yearly greenhouse gas emissions would decrease by 5.3 million metric tons.

Further more, a 40-watt equivalent EnduraLED is already on the market, while Phillips plans to introduce the 60-watt equivalent by the end of 2010.
