Long Beach, CA, has replaced about 1,750 high pressure sodium streetlights with LEDs, according to The Long Beach Post.
This marks the completion of the first phase of the retrofit project, the story said. The Port of Long Beach Community Migration Grant of $659,000 paid for the changeover. The second phase of the project will replace about 24,000 more high pressure sodium lights and will cost about $6.1 million. Financing will be through cost savings of the LEDs and $3.2 million in rebates from Southern California Edison.
The LEDs are expected to last about 100,000 hours, which represents about 24 years of use, the story said.
This spring, a compromise between the astronomical community and city officials in Las Cruces, NM on LED street lighting was reached, according to the Las Cruces Sun. The challenge was that the brightness of the newly installed LEDs could interfere with astronomical activities.
