This page contains links to archived lighting market characterization studies published by the U.S. Department of Energy. These studies were intended to present objective market analysis based on the most recent, referenceable data available at the time of preparation of the reports. While coordinated with other DOE data sources and policies, these reports also include data from a variety of non-governmental sources in order to produce, to the extent possible, unbiased analysis. These reports are intended solely for the benefit of the public, in order to help regulators, manufacturers, energy program managers, and others make informed choices and decisions related to solid-state lighting. Readers of these reports are urged to conduct their own due diligence and research before using the analysis presented in these reports. More recent versions of some of these reports are available.
