The U.S. Department of Energy has released a GATEWAY report on the experiences of the City of Portland, OR, in converting its street lighting from high-pressure sodium to LED. Such large-scale conversions are rarely simple matters, and the Portland Bureau of Transportation was an early investigator of LED street lighting and one of the first public agencies to join DOE's Municipal Solid-State Street Lighting Consortium, so learning how the city addressed the challenges it encountered can be especially helpful to other cities that are implementing or considering their own lighting transitions.

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.
