by Ann Withanee — October 7, 2011—Building owners and facilities executives facing new lighting regulations calling for more energy-efficient light bulbs may be interested in a new light-emitting diode (LED) bulb from Philips. Named on BuildingGreen’s list of the Top-10 Green Building Products for 2012, Philips’ EnduraLED A19 was engineered as a replacement for the 60-watt incandescent light bulb and is reportedly the first such LED bulb to be Energy Star qualified. The LED bulb was displayed at the U.S. Green Building Council’s Greenbuild conference held recently in Toronto.
When turned off, the EnduraLED A19 has a unique yellow appearance due to the phosphors used, but once turned on, the yellow becomes a warm-white light with a 2700 K color temperature—similar to a typical 60-watt incandescent.
This bulb is currently available in a 12.5-watt version with a color rendering index (CRI) of 80, but a 10-watt version with a CRI of 90 recently completed 18 months of testing to become the first winner of the U.S. Department of Energy’s Bright Tomorrow Lighting Prize (L Prize) competition awarded to an LED capable of meeting performance metrics for light quality, color, and output. This latter version should be available in 2012. The EnduraLED A19 is fully dimmable, has an average rated lifespan of 25,000 hours, and comes with a three-year limited warranty. Philips also makes 40- and 75-watt incandescent-equivalent bulbs.
What makes this product green?: equipment that conserves energy and manages loads; improves light quality; exceptional durability or low-maintenance.
