DOE Releases Feasibility Assessment of LED Roadway Lighting on the Golden Gate Bridge

The U.S. Department of Energy (DOE) has published a technical feasibility assessment of replacing existing high-pressure sodium and low-pressure sodium roadway lighting on San Francisco's Golden Gate Bridge. The goal was to identify solutions which would reduce maintenance and energy use without compromising the quantity or quality of existing illumination. However, the historic status and high efficacy of the existing luminaires—as well as their accepted color characteristics—present challenges for energy-saving alternatives.
