New LED streetlights come to Fremont

October 28th, 2010 by master

We’ve heard from some readers that City Light has installed those new LED (light-emitting diode) streetlights in parts of Fremont.  They cast an immediately noticeable brighter, whiter glow.

It’s all part of a citywide upgrade to LEDs that began this summer. A July 2010 press release about the new streetlights explained their expected benefits:

“We are entering a new era in street lighting,” Superintendent Jorge Carrasco said. “LEDs use 40 percent less energy and last three times longer than the high-pressure sodium lights that have been the standard for the past 30 years. That means better reliability, less maintenance, a longer life cycle, and lower operating costs for our customers.”

City Light will install 5,000 LED streetlights in residential neighborhoods this year and a total of 40,000 during the next five years. The 2010 installations will take place from the Ship Canal to 65th Street. The utility also started pilot projects to test LED streetlights on arterial roads.

The LEDs being installed generate a white light that is comparable to moonlight. This enhances peripheral vision and depth of field, making it easier to see small objects in the road and reducing the color distortion caused by the amber glow of existing high-pressure sodium lights. Finally, the LEDs provide better control over where the light is directed, reducing spillover into home windows and the night sky.

Here’s a demonstration of the difference between the old high-pressure sodium lights and LED ones:

If your street has gotten its new LED lights, what do you think of them?
