The California Lighting Technology Center (CLTC) recently demonstrated Philips Day-Brite NiteBrites HID wall packs at California State University, Chico. The demonstration included replacing 13 150W high pressure sodium wall packs and one 70W HPS tall wall pack with 14 new bi-level HID fixtures at Shasta and Lassen halls.

The retrofit increased light levels of the pathways surrounding the dormitories, as well as provided a high color quality and color temperature (4000K). In addition, the retrofit resulted in 42% energy savings, which translates into 4,550 kWh.
