Lighting Systems Technology Research Team
U.S. Department of Energy's Lighting Systems Technology Research Team and partners work together to reduce lighting energy use by sharing insights and experiences related to emerging lighting and control systems and documenting the application of solutions. By developing resources like lighting specifications and application guidance, the team helps build confidence and demand for higher efficiency technology.
LED Troffer Retrofit Lighting and Controls Best Practices
This guide (U.S. Department of Energy) outlines the best practices for retrofitting LED troffer lighting and controls. The vast majority of lighting in U.S. commercial buildings is provided by fluorescent troffer ceiling fixtures. There are currently over 350 million installed troffers using more than 65 million kWh (the annual energy usage of 6 million U.S. homes). Retrofitting these fluorescent troffers to light-emitting diode (LED) sources offers the potential for enormous energy savings.
