| The U.S. Department of Energy (DOE) has released the Phase III report from the solid-state lighting (SSL) demonstration of LED street lights in Oakland, CA.
This GATEWAY demonstration report, prepared by Pacific Gas & Electric and Energy Solutions, provides an overview of project results measured over a 12-month period, including comparison to Phase II luminaires, energy consumption and illuminance levels, and economic analysis.
In this project, four LED luminaires on one of the Phase II streets were replaced with next-generation LED luminaires (58 W) from the same manufacturer, with the same chip and driver.
Key findings include:
- Energy savings increased by 25% relative to Phase II (LED luminaire wattage dropped from 78W to 58W) and by 52% relative to the baseline system (from 121W to 58W).
- Luminaire cost decreased by 34% between Phase II and Phase III (from $610 to $400).
- Lighting performance was maintained.

This commercial LED lighting demonstration is one of a number of DOE GATEWAY demonstrations that showcase high-performance LED products for general illumination.
