Streetlight Retrofit (LED lighting)

streetlightsOverview: In accordance with the Climate Action Plan, the City of Berkeley is replacing conventional street lights with more efficient lighting technologies to reduce energy and greenhouse gas emissions. Light-emitting diode (LED) lighting provides an improved, whiter, brighter light quality which enhances night visibility while lowering energy consumption, greenhouse gas emissions and maintenance costs. LEDs emit directional light which provides more control over what is lit (streets and sidewalks) versus what should remain dark (the night sky). This makes it easier to comply with the Dark Skies Initiative (http://www.darksky.org/), which aims to reduce light pollution and its associated wildlife impacts.

Saving Energy: Streetlights make up 32% of the City's municipal electricity load and account for 900 metric tons of carbon dioxide emissions annually. LED streetlights cut energy and greenhouse gas emissions in half. Following on the success of LED pilot projects in the Marina and along Telegraph Ave, all City streetlights are scheduled for replacement with LEDs in 2014.

Citywide LED Replacement Project: Installation of LED streetlights throughout the City is expected to begin in the summer of 2014. Approximately 8,000 high-pressure sodium (HPS) and metal halide streetlights, including path and park lights, are scheduled to be replaced. The project will result in significant energy and cost savings for the City. In addition to using less energy, LEDs have a longer lifespan which reduces maintenance costs. The replacement project will also change out some fixtures for consistency and make any future replacements easier. The new fixtures will be mounted on the existing light poles.

Marina and Telegraph LED Pilot Projects: In 2012 to 2013, over 100 streetlights were replaced with LED lights at the Berkeley Marina and along Telegraph Avenue.

Benefits of LED Lighting:

  • Improved lighting conditions for drivers and pedestrians alike
  • Lower energy consumption
  • Reduced maintenance and replacement costs
  • Improved night visibility due to higher color rendering and higher color temperature
  • Increased light uniformity and distribution of light between poles
  • Enhanced directionality and controllability, reduced light pollution
  • Significantly longer lifespan
  • Instant-on with no run-up or re-strike delays
  • Less toxic, LED lights contain no mercury or lead and are 100% recyclable
  • Lower environmental footprint
  • Smarter lighting control technology including remote monitoring and control for lights

Public Feedback: We are interested in your feedback. If you have questions or comments on the new LED lighting, please contact Billi Romain by email at bromain@cityofberkeley.info or by phone at 510-981-7432.
