The city of San Jose, California, has issued a public update on the status of its LED streetlighting program. The city’s streetlighting conversion initiative calls for the replacement of all of its 62,000 existing streetlights. In addition to deciding to use energy efficient streetlights, the city has also committed to installing adaptive controls. The shift to LED streetlighting will enable the city to achieve its environmental goal of energy cost savings and dark sky compliance.
The launch of the city’s program began in 2008 with a demonstration pilot. The pilot enabled city officials to test energy efficient streetlight fixtures, explore adaptive technology, solicit feedback from citizens, and develop goals for the city’s streetlighting program. Adaptive technology is of significant interest to the city of San Jose because of the astronomical research conducted at the Lick Observatory. The city is in the process of installing 3,500 BetaLED streetlight fixtures. Selected LED streetlight fixtures are embedded with power line signaling technology from Echelon.
The city’s streetlight inventory includes 20,000 low pressure sodium (LPS) streetlights on major streets; 1,600 LPS streetlights in the downtown corridor; 30,000 LPS streetlights in residential neighborhoods; and approximately 6,000 decorative streetlights. The decorative fixtures are not currently targeted for replacement.
Due to the large number of streetlights targeted for replacement, city officials have prioritized installation on the city’s major streets followed by the downtown corridor. Officials are also exploring a variety of financing options including an infrastructure bond measure.
