The U.S. Department of Energy's GATEWAY program reports on a trial installation of Tunable White LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, providing valuable insights into the use of this technology.
Installed in August 2016, the LED systems provide the ability to vary the spectral power distribution (SPD) across four preset conditions associated with nominal CCTs of 3000 K, 3500 K, 4200 K, and 5000 K. The controls also provide for preset scenes to vary the on/off status and dimming level of different luminaire zones within the room, to better support such classroom functions as audiovisual presentations.
