DOE Releases Report on LED Environmental Testing

The U.S. DOE has released a new study addressing the potential environmental impacts from landfill disposal of three light-source technologies used in residential homes: incandescent, CFL, and LED. All three lamp types contained some hazardous elements which, while generally below Federal landfill limits, in some instances exceeded the more restrictive California limits. The report, LED Environmental Testing, covers the third part of a larger DOE study to assess the life-cycle environmental and resource impacts of LED lighting products in relation to the two other types of lighting. Altogether, the three-part study found that LEDs currently have the lowest environmental impact, and that the rapid pace of LED technology improvements will widen that gap considerably over the next five years.
