LED Lighting Riding Price-Performance Curve (Martin LaMonica, November 5, 2012), Technology Review)
Posted by Orrin Judd at November 6, 2012 4:50 AMAt first blush, expensive LED light bulbs are an unlikely technology to succeed with consumers. But the benefits of LEDs for lighting are becoming clearer, in terms of both cost reductions and high-tech features.Best Buy last week introduced its Insignia line of consumer light bulbs in the familiar A19 shape. The bulbs use LEDs from Cree and give an amount of light equivalent to a 60-watt or 40-watt incandescent lamp. They're designed to last over 20 years, give off a white light at 3,000 Kelvin, and have a color rendering index of 80, according to Cree.The cost for the 60-watt equivalent, which consumes 13 watts, is $16.99, and a 40-watt-equivalent bulb costs $13.99. That's a lot more expensive than comparable compact fluorescent or incandescent bulbs. But the Insignia shows that LED lighting costs are falling.Two years ago, similar products from other manufacturers cost more than double what they do now.
