DOE Report Studies Tunable Lighting in Three Texas ClassroomsThe U.S. Department of Energy’s Gateway program has released a new report on a trial installation of tunable-white LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, which provides valuable insights into the use of this technology in a real-world setting.

The LED systems were installed in August 2016 and provide the ability to vary the spectral power distribution (SPD) across four preset conditions associated with nominal CCTs of 3000K, 3500K, 4200K and 5000K. 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.

Among the key takeaways:
