270 San Leandro Street Lights to Get Energy Efficient Upgrade

BetaLED Street LightSan Leandro's street lights will become more energy efficient under a new contract that will replace 270 high pressure sodium (HPS) lights with light-emitting diodes (LEDs). Similar lights are in place on the Hayward-San Mateo Bridge.

The contract, awarded to Omega Pacific Electrical Supply, is worth $83,320. Omega will be installing LED streetlights manufactured by BetaLED, a division of Wisconsin-based Ruud Lighting. Funding for the project comes from an Energy Efficiency and Conservation Block Grant that is funded by the American Recovery and Reinvestment Act of 2009 and from PG&E rebates for purchasing qualified LED fixtures.

A similar program to replace traffic signal lights with energy-efficient LEDs was done in the early 2000s, according to San Leandro Public Works Director Mike Bakaldin. All green and red traffic signals and most of the yellows are now LEDs. Bakaldin noted that the red LEDs have been very reliable, but the green LEDs had to replaced within a few years.

The City of San Leandro has more than 5,000 street lights, so these conversions include about 5% of existing street lights. However, the energy savings is estimated at 20 to 50% of an HPS light and LEDs are expected to last much longer than HPS lights, reducing maintenance costs. Other advantages include no lead or mercury that is in many HPS light fixtures, improved lighting from the higher quality of the light emitted, and no need to warm up before they are fully lit.

Update: The lights will be installed in the Bonaire area where a pilot project was started in 2010.
