Among the key findings of the report, entitled LED Manufacturing and Performance are:
- Electricity consumption over an equivalent period of lighting service is far greater for the incandescent lamp and is the dominant contributor to environmental impacts.
- Because of its low efficacy, the incandescent lamp is the most environmentally harmful of the three lamp types considered, across all 15 impact measures.
- The CFL is slightly more harmful than the 2012 LED lamp (today's LED technology) on all impact measures except hazardous waste landfill, where the LED lamp's large aluminum heat sink causes greater impact because of the energy and resources consumed in manufacturing it (which produces significant waste disposed of in landfills).
- The best-performing light source is the LED lamp projected for 2017, whose prospective impacts are expected to be about 50 percent lower than the 2012 LED lamp and 70 percent lower than the CFL.
