Overview of the Lighting Research Group

The Lighting Research Group at Lawrence Berkeley National Laboratory performs research aimed at improving the energy efficiency of lighting systems in buildings and homes, throughout the State of California and across the Nation. The goal is to reduce lighting energy consumption by 50% over twenty years by improving the efficiency of light sources, and controlling and delivering illumination so that it is available, where and when needed, and at the required intensity. Research in the Lighting Group falls into three main areas: Sources and Ballasts, Light Distribution Systems and Controls and Communications. Click on a link below for more information about each of these research areas.

Sources and Ballasts investigates next generation light sources, such as Light Emitting Diodes, and the power supplies (ballasts) that operate them.

Controls and Communications investigates how digital technologies, such as Bluetooth, can be applied to building lighting control systems to increase building efficiency and improve occupant comfort and productivity.

Light Distribution Systems researches how new light sources can be incorporated into the design of the luminaire to improve efficiency of light delivery and add functionality, such as dimming.


Research in the LBNL Lighting Group is supported by the Assistant Secretary for Energy Efficiency and Renewable Energy, Office of Building Technology, Building Technologies Program, of the U.S. Department of Energy under Contract No. DE-AC03-76SF00098 and by the California Energy Commission's Public Interest Energy Research (PIER) Buildings Program.
