Oakland Will Upgrade 30,000 Street Lights With GE LED Fixtures

GE Lighting has announced that the city of Oakland, California is in the process of retrofitting 30,000 street lights with GE Evolve LED Roadway Scalable Cobrahead fixtures. The city is converting high-pressure sodium (HPS) lights that range from 70–400W along the breadth of the city’s roadways with the GE product family that offers models that can deliver a variety of lumen packages, as the scalable name implies.

The city of Oakland is projecting that the solid-state lighting (SSL) retrofit will deliver 40% baseline energy savings relative to the HPS lighting. And the initial maintenance savings will come via the inherent longer life of the LED-based fixtures.

“The program again proves that Oakland is a national leader in civic innovation, saving money and helping to protect the environment,” said Oakland Mayor Jean Quan. “These lights burn less energy, which means we’re reducing our energy bills and our energy use at the same time, and their much longer lifespan also means we’re reducing our e-waste footprint. Everyone who has contributed to this project is helping Oaklanders and making our city proud.”

Still, the savings, both in the area of maintenance and energy, could be enhanced down the road through adaptive controls and a network. Graybar recommended a controls-ready luminaire and the city could add support for a network in the futures. Such an upgrade could enable dimming the lights during low-traffic periods to further slash energy use and automation of maintenance tasks.

The GE LightGrid technology is being trialed in the city of Los Angeles and combines a wireless network and the use of GPS receivers on light poles to quickly identify the location of failed lights.
