The U.S. Department of Energy has released a report on a GATEWAY demonstration, in which maintenance and energy costs were significantly reduced while retaining the quality of light when LED modules replaced 87 halogen lamps in existing wall washers at the University of Maryland's Clarice Smith Performing Arts Center. The project began with mockups in the spring of 2014, with final installation completed in March 2015. The primary goals were to maintain the visual appearance of the space while reducing maintenance costs, with energy savings considered an additional benefit.
