Wall packs offer an effective means of illuminating building perimeters, bolstering security and aiding wayfinding, but many are limited in terms of their efficiency, with minimal or nonexistent cutoff. Moreover, because wall packs typically operate in areas with low occupancy rates, they often waste energy fully illuminating vacant spaces for hours at a time every night.
Due to the potential use of xenon lamps in outdoor applications, CLTC in collaboration with PG&E, developed an evaluation and testing program for xenon technology used in general illumination, outdoor applications. The research included under this project informed utilities about the performance and reliability of xenon lamps in these applications as compared to Light Emitting Diodes (LED), induction or other appropriate parking and area lighting solutions.
To address California’s critical need for targeted, practical technology improvements that reduce lighting energy use and advance building energy-efficiency, in 2009, the California Energy Commission initiated a comprehensive lighting research, development, demonstration and outreach program in partnership with the California Lighting Technology Center.
