DOE Publishes GATEWAY Report on High-Luminous-Flux LED Lighting in a High-Temperature Environment

The U.S. Department of Energy has released a GATEWAY report on a trial demonstration in which the incumbent quartz metal halide (QMH) area lighting was replaced with LED at three pole locations along a 7.2-mile stretch of the Yuma (Arizona) Sector Border Patrol Area. This high-luminous-flux and high-temperature application is not unique, and similar applications can benefit from the findings of this installation – including correctional facilities, military bases, and, more generally, street and area lighting.
