San Francisco Water, Power and Sewer is beginning a city-wide project late this year to replace 18,500 high-pressure sodium street light fixtures with LED fixtures. The new fixtures will use 50 percent less energy than the existing street lights and will cost far less to maintain since they only have to be replaced every 15 - 20 years compared to the current bulbs that have to be replaced every four years.
The swapping out of the lighting fixtures is expected to take 30 minutes per street light with the whole project being completed in about 14 months.
The new lights have more benefits than just the energy and cost savings. The lights will have smart controllers that let the city remotely monitor and adjust their light level and alert maintenance crews when the lights fail or are about to fail.
