February 28, 2012... The City of Carpinteria in November 2011 completed its retrofit project of replacing all its existing city-owned 138-Watt high-pressure sodium (HPS) decorative street lights with 29-Watt LED-based pendent lights. The Santa Barbara County city is a coastal community of 13,040, with small-town charm, beautiful beaches and breathtaking mountain views. It hosts the annual California Avocado Festival.
The lights, which were designed an engineered at the LEDtronics factory in Southern California, are located on several blocks of Linden and Carpinteria Avenues in the downtown area and include lights on the Amtrak rail platform and its adjoining public parking lots.
According to the city’s calculations, each of the 199 HPS lamps at 138 watts each consums about 604.4 kWh annually. So for the 199 lamps this translates to a total of 120,284 kWh and an energy cost of $15,035 (at $0.125 per kWh, 12 hours of operation each evening).
