LED Street Lighting and Network Controls - San Francisco, CA

This report summarizes an assessment project conducted to study the performance of light emitting diode (LED) luminaires with network controls in a street lighting application. The project included installation of LED street lights with network controls on public roadways in San Francisco Public Utilities Commission (SFPUC) service territory in San Francisco, California.  Quantitative light and electrical power measurements as well as surface and overhead photographs from a maintenance bucket truck were taken to compare base case high pressure sodium (HPS) performance with that of the LED replacement luminaires. Network controls functionality and monitoring capabilities were also tested and qualitative satisfaction with the system was gauged through a user survey. Estimated economic performance of the LED streets and network controls was compared to that of the incumbent HPS street lights.
