by Jbs022009c3 — February 23, 2009—The US Department of Energy (DOE) recently published the report from a San Francisco, California, demonstration of LED street lighting. This GATEWAY demonstration report, prepared by Pacific Gas & Electric and Energy Solutions, provides an overview of project results including lighting performance, cost effectiveness and potential energy savings.
In this project, four manufacturers’ LED street lights were installed on four public avenues in the Sunset District of San Francisco, each with a total of five street lights from the beginning to end of the block. On each avenue, 100-watt nominal high-pressure sodium (HPS) luminaires were replaced with new LED luminaires (each street featuring a different LED product).
While lighting performance varied among the LED luminaires assessed, energy savings potential was high in each case, with energy reductions ranging from 50% to 70% over the current HPS system. The study found that the products with better lighting performance were also more economically attractive.
