This page contains links to lighting market characterization studies published by the U.S. Department of Energy, plus information on current studies under way. These studies are intended to present objective market analysis based on the most recent, referenceable data available at the time of preparation of the reports. As new information becomes available, DOE will make efforts to update these studies as necessary. 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.


  • 2020 LED Manufacturing Supply Chain
    Characterizes the globalized manufacturing supply chain of LEDs and LED lighting products, investigates the economic impacts of this supply chain on the United States, and identifies opportunities for increased domestic manufacturing. (Report, March 2021)
  • Adoption of Light-Emitting Diodes in Common Lighting Applications
    Models the current state of the U.S. general-lighting market and provides analysis on realized and potential energy- and money-saving benefits associated with LED lamps and luminaires. (Report, August 2020)
  • Energy Savings Potential of SSL in Agricultural Applications
    Examines the energy-saving potential of LED lighting in agricultural applications using an analysis that considered three indoor horticultural lighting categories: lighting supplemented greenhouses, high intensity sole-source farms, and sole-source indoor vertical farms typically growing leafy greens. To characterize animal lighting, the analysis investigated the three largest markets of livestock in the U.S. that use lighting – poultry, swine, and dairy farming. (54 pages, June 2020)
  • Energy Savings Forecast of Solid-State Lighting in General Illumination Applications
    Report which models the adoption of LED lamps and luminaires in the U.S. general-lighting market, along with associated energy savings, based on the full potential DOE has determined to be technically feasible over time. (128 pages, December 2019)
  • Energy Saving Opportunity from Advanced LED Lighting Research
    Estimates the energy saving opportunity made possible by certain lighting research planned by Pacific Northwest National Laboratory. (Report, October 2019)
  • Energy Savings Potential of SSL in Horticultural Applications
    Examines the energy-saving potential of LED lighting in horticultural applications using an investigation of the three main categories of indoor horticulture: supplemented greenhouses, non-stacked indoor farms, and vertical farms. (34 pages, December 2017)
  • 2015 U.S. Lighting Market Characterization
    Detailed estimates of the installed stock, energy use, and lumen production of all general-illumination lighting products operating in the U.S. in 2015. (135 pages, November 2017)
  • OLED Lighting Products: Capabilities, Challenges, Potential
    Report that focuses on the potential for architectural OLED lighting – describing currently available OLED products as well as promised improvements, and addressing the technology and market hurdles that have thus far prevented wider use of OLEDs. (37 pages, May 2016)
