Philips has introduced their 12 watt EnduraLED light bulb, a replacement for the standard light bulb that promises to use up to 80% less energy and last 25 times as long, which could have significant impact if widely adopted.
Every year more than 425 million 60-watt incandescent light bulbs are sold in the United States, representing approximately 50% of the domestic incandescent light bulb market. According to calculations by Philips, this LED replacement has the potential to save 32.6 terawatt-hours of electricity in one year, enough to power the lights of 16.7 million U.S. households or 14.4% of the total number of households in the entire US. It would also eliminate the generation 5.3 million metric tons of carbon emissions annually.
Unfortunately, according to Engadget the EnduraLED will be sell at US$60 per bulb, which will undoubtedly be a disadvantage for Philips and the entire planet.
