This brief outlines PNNL’s research findings for the performance of LED lighting systems in three Texas classrooms. At the end of the school year, PNNL’s evaluation showed at least 58 percent energy savings overall for the LED lighting systems compared with the fluorescents. These savings came from the greater efficiency of LED lights. Even more savings, beyond the 58% attained with solely LEDs, can be achieved with the ability to dim the lights. Additionally, this brief includes how the installation of LED systems do more than enhance energy savings, and can provide learning environment benefits for educators and students.
