As much as we love the warm glow of incandescent lightbulbs, their days are numbered as we have more energy-efficient methods of creating light. CFL may be the popular solution now, but the real future may be in light-emitting diodes.
Royal Philips Electronics is showing EnduraLED A21 17-watt light bulb at the Lightfair International tradeshow this week, which is designed to replace a 75-watt incandescent bulb.
Thanks to LED's properties, this 17-watt can replace the output of a 75-watt while reducing energy consumption by 80 percent and lasting 25 times longer.
The EnduraLED A21 17-watt, which uses the company's high-power, next-generation Luxeon LEDs, has a color temperature of 2700k, a color rendering index (CRI) of 80, and a rated life of 25,000 hours. The new bulb will be submitted to ENERGY STAR in the coming months for qualification testing.
Philips estimates that about 90 million 75-watt incandescent light bulbs are sold annually in the United States. Switching to this LED replacement has the potential to reduce energy use by 5,220 megawatts of electricity, a cost savings of approximately $630,000,000 annually. According to Philips estimates, switching to the EnduraLED 21 17-watt could also eliminate 3,255,205 million metric tons of carbon emissions annually, or the equivalent of removing nearly one million cars from the road.
Over its lifespan, the EnduraLED A21 17-watt could save a business or household about $160 per bulb. The real barrier to this cool lighting technology to really gain any acceptance in the household is the price, which is expected to be in the range of $40 - $45 when it goes on sale in the fourth quarter of 2011.
