LED Street Lighting - San Francisco

This report summarizes an assessment project conducted to study the performance of light emitting diode (LED) luminaires in a street lighting application. The project included installation of four manufacturers’ LED street lights on public roadways in San Francisco, California. Quantitative light and electrical power measurements as well as surface and overhead photographs were taken to compare base case high pressure sodium (HPS) performance with that of the LED replacement luminaires. Estimated economic performance of the LED luminaires as compared to HPS street lights was also calculated and qualitative satisfaction with the LEDs was gauged through a resident survey.
