The U.S. Department of Energy’s Memorandum of Understanding (MOU) with the Illuminating Engineering Society (IES) underscores DOE’s commitment to support the development of needed metrics and standards for solid-state lighting (SSL) technology.

The MOU serves to solidify and strengthen the ongoing collaborative relationship between DOE and IES. The agreement outlines six broad goals for joint DOE-IES efforts:

  • Promote and support the DOE Programs by means of input from technical experts, and development of appropriate IES standards and procedures.
  • Develop and maintain guides and procedures to assist the lighting measurement and application community in the photometric measurement of solid state lighting devices and other technologies to (i) support DOE programs, and (ii) provide consistency and uniformity in photometric reports.
  • Develop and maintain industry standards that include a focus on energy efficiency strategies to benefit design professionals and users.
  • Encourage the participation of DOE personnel in IES technical committee activities and provide the opportunity for dissemination/publication of related research.
  • Develop and maintain appropriate educational modules for inclusion in IES course materials for use by the Society’s Sections and other organizations.
  • Coordinate research & development plans with the DOE Solid-State Lighting Program on numerous science, engineering, and application concepts.

IES is the recognized technical authority on illumination, and communicates information on all aspects of good lighting practice to its members, the lighting community, and consumers. For more information on IES, visit

IES Activities

IES works with DOE on developing needed lighting industry metrics, test methods, and standards. IES also partners with DOE on stakeholder events including workshops, symposia, and webinars.
