The story at the Press-Telegram says that the first phase of the project will be the replacement of 1,750 intersection lights over two months. It will be funded by a Port of Long Beach Community Migration Grant of $659,000.
The second phase will repace more than 24,000 high-pressure soldium lights. The year-long project will cost about $6.1 million, which will be about halved by a rebate of $3.2 million from Southern California Edison.
The city expects the LEDs to last about 100,000 hours – 24 years – with usage of 12 hours per day. The lifetime savings of the retrofit will be about $15.1 million, the story says.
That’s not the only LED retrofit going on in California. The Buzz Oates Group in September said that it has retrofit almost all of the 25 million square feet of commercial property it has under management. Among other things, the company was attracted to the long life of LEDs. Its previous lights had a lifespan of 5,000 hours, far less than the 100,000 hours it expects from the LEDs.
