According to a report recently released by Department of Energy, LED lamps have a slightly lower environmental impact than compact fluorescent lamps and a significant environmental advantage over incandescent lighting through the lifetime of the products.
 
Titled “LED Manufacturing and Performance,” is the second part of a DOE project to assess the life-cycle environmental and resource costs in the manufacturing, transport, use and disposal of LED lighting products.
 
It has concluded that the life cycle energy consumption of LEDs and CFLs are similar — about 3,900 MJ per 20 million lumen-hours. LEDs consume 12.5 watts of electricity to produce about the same amount of light as a 15-watt compact fluorescent lamp or a 60-watt incandescent.
