Part of the University of California, Davis, the California Lighting Technology Center (CLTC) is a not-for-profit research, development and demonstration facility dedicated to accelerating the development and commercialization of electric building systems & controls technology in pursuit of decarbonization, grid resiliency, and community wellbeing. The center includes full-scale laboratories for research and development, as well as prototype and product testing. Long-term funding for the work done at CLTC is provided by private and public agencies, including CLTC partners.

Working in partnership with designers, manufacturers, end users, utilities, government agencies, and others, CLTC commercializes energy-efficient lighting and daylighting technologies, producing new technologies, inventions, patents, and license agreements. CLTC also provides engineering specifications, market research, resources, lighting guides, working papers, and white papers. The center conducts technology demonstrations, and publishes reports and case studies on these projects. The center's faculty and staff also provide curriculum and instruction for education and training courses, in addition to conducting workshops, seminars and outreach activities.
