How LEDs will Change How Cities will Look at Night


LA at night before and after LEDs were installed.

More and more cities are not changing their streetlight with LEDs. Many say that this has dramatically changed how the streets look at night. Ed Ebrahimian loves to stare out the plane window on night flights home to Los Angeles. Next time you fly into L.A. late, take a good look and see why. Five years ago a bright orange blanket of light used to saturate the city and stain the air above. Today it’s a metropolis aglow with tens of thousands of cool silvery pinpoint lights. The grid is clearer. The skies are blacker. “The lights look like candles now, and they aren’t glaring at all,” Ebrahimian gushes. “The sky glow is the most amazing thing I’ve seen in my life.” Ebrahimian has good reason to be enthused. As director of L.A.’s Bureau of Street Lighting, he’s overseeing one of the largest relighting projects in the world, spending $57 million to retrofit the city’s 215,000 lights, which come in more than 400 styles. The money has gotten him only to lamppost number 155,000 after five years. Replacing the remaining 60,000, including most of the decorative ones, will cost $50 million more. Read on at Forbes.
