The U.S. Department of Energy (DOE) has published a report that looks at the direct and indirect material and process inputs to fabricate, ship, operate, and dispose of LED lamps, compared with incandescent lamps and compact fluorescent lamps (CFLs). Entitled LED Manufacturing and Performance, it is the second part of a larger DOE project to assess the life-cycle environmental impacts and resource costs of LED lighting products in relation to comparable traditional lighting technologies. The report uses the conclusions of Part 1, Review of the Life-Cycle Energy Consumption of Incandescent, Compact Fluorescent, and LED Lamps, as a point of departure to produce a more detailed and conservative assessment of the manufacturing process and use it to compare the three lighting technologies, taking into consideration a wider range of environmental impacts. This report is the most comprehensive study of its kind for LED products, addressing both energy and environmental impacts, and is the first public report to consider the LED manufacturing process in depth.
