Concept

The objectives are to test, analyze, and determine the potential of electronic ballasts for HID lighting systems in cooperation with manufacturers. Control strategies will be identified for commercial, industrial, and municipal applications. Also, appropriate recommendations may be developed for integrating this technology into current state codes.

Solution

The measurements to characterize the performance of HID lamp-ballast systems are being performed in the laboratory at the Lawrence Berkeley National Laboratory (LBNL). Both electrical and spectral performance measurements have been completed for low wattage systems (< 175 watts). Testing is currently underway for higher wattage systems. In related work, LBNL is also testing HPS electronic ballasts for the City of Oakland.
