By 2020, LEDs May Rival Incandescent Bulbs in Cost without Rebates

New data from the U.S. Energy Information Administration shows how far the cost of LEDs has fallen since 2010. The agency projects that the technology will approach price parity with CFLs and incandescent bulbs around the end of the decade. A 2012 report from the U.S. Department of Energy, however, forecasts that LEDs will make up only 36 percent of lumen-hour sales in the lighting market in 2020, a figure that is expected to grow to 74 percent by 2030. But the DOE has already revised its projections upward three times in the past five years. The department now has a goal of 224 lumens per watt efficacy at $0.70 per thousand lumens by 2020. EIA’s projections would suggest that this is too ambitious a goal to achieve; its forecast is closer to 150 lumens per watt by 2020.
