City Replacing Street Lights with LEDS at Some Intersections
The energy-efficient LEDs will replace high-pressure sodium street lights at 82 intersections with traffic signals.
From an Alameda Municipal Power press release:
Alameda Municipal Power (AMP) and the City of Alameda's Public Works have partnered to replace 251 existing high pressure sodium street lights with energy-efficient LEDs (light-emitting diodes) at 82 traffic signal intersections, saving the city an estimated $26,000 per year in electric costs and lowering greenhouse gas emissions.
According to AMP's Rebecca Irwin, the street lights being replaced are the ones that sit atop traffic signal poles (although not every traffic signal has one), but not the traffic lights themselves.
LED street lights last longer than high pressure sodium lights — about 12 years compared to 5.5 years — thereby significantly reducing maintenance costs. Moreover, LED lights provide much better illumination and color distinction at night, while reducing sky glow — the artificial illumination of the night sky.
This is the city's third LED streetlight conversion project and it supports the city’s goal of reducing greenhouse gas emissions by 25 percent below the 2005 baseline level. AMP plans to install more LED streetlight projects in the coming year.

The $107,000 project qualified for a $33,000 rebate under AMP’s “Commercial Lighting Retrofit Program,” which offers rebates and guidance to Alameda businesses and government agencies that install energy-efficient lighting. With an estimated annual energy savings of $26,069, AMP projects that the city will recoup its costs in less than three years.
The traffic signal street light replacement is under way now and is expected to be completed in mid-December.
