Los Angeles is literally basking in a whole new glow.
The city has decided to replace its street lights and bus stop lighting with LEDs. The bus stop lighting will be solar-powered and off the grid.
LA’s Bureau of Street Lighting has been actively testing out different types of energy efficient lighting to replace the public lighting that currently includes a combination of incandescent, mercury vapor, metal halide, and high pressure sodium lights.
In 2009, the agency began an LED street lighting energy efficiency program to actively replace its existing 209,000 streetlights. When complete, the city’s energy consumption for public lighting should be cut by 40 percent and save 40,500 tons of carbon emissions per year, according to city statistics.
Now the city has decided on which specific lights to go with. Many of the street lamps will be LEDway streetlights from BetaLED. The solar-powered bus lamps are EverGen lights from Carmanah Technologies. Because the bus lights are self-sufficient, they will not need to be tied into the city’s electric grid and will allow the city to remain lit even in the event of a blackout.
In a statement released Tuesday, Carmanah said its lights will also give the city more freedom to replace existing lights or introduce lights in new places without having to dig up sidewalks or tie into electricity poles, cutting down on installation costs.
But in addition to making the city more energy efficient, the switch from an abundance of high pressure sodium lights across the city’s highways to LEDs is also drastically changing the city’s look. Before and after photos provided by the city of the 6th Street Bridge over the Los Angeles River illustrate a clear change in tint from orange to whiter lighting.
