Switching to energy efficient LED luminaires fitted with the Owlet Nightshift System, the city of San Jose, California has reduced its energy costs and CO2 emissions by 47 percent. The city of San Jose has achieved a milestone in one of the largest streetlight conversion projects ever launched in the U.S.A. The city has started to retrofit more than 18,000 fixtures equipped with low and high-pressure sodium lamps to energy efficient LED luminaires equipped with the Owlet Nightshift control system. This project is an important goal of the city’s award-winning San Jose Green Vision, which aims to enhance visibility and safety at night while reducing energy and carbon emissions. Schreder, a company which provides smart lighting solutions for over 45 companies worldwide has helped the city of San Jose to achieve this milestone. According to Schreder statement a total of 18,127 luminaires will be replaced at a stretch of 128kms in the south-east area of the city. The smart lights are equipped with a LuCo-PD a technique which enables the luminaires to extend their basic lifetime by reducing the initial level of light (to avoid over lighting). It will also be dimmed during the night when there is little traffic on the roads so that they will use up to 60 per cent less electricity than the sodium based lamps. A total of 6,000 of these smart luminaires were installed for the in February. The entire installation will be finished for May.
