CLTC is developing and demonstrating a high-low HID exterior lighting system that operates at a low level during unoccupied night periods and at a high level during occupied night periods. A beta-site demonstration of Bi-level fixtures is installed at the Mondavi Center in Davis, CA.

Conceptual approaches, preliminary designs and lighting system prototypes are being developed for two applications: pole-mounted and wall-pack fixtures. The project team is working to refine the design of an HID exterior lighting system with integrated controls. Baseline evaluations of the field test site will be conducted with follow up field demonstrations of prototyped systems.

OBJECTIVE:
To develop an HID exterior lighting system that switches from a low power-saving mode with no occupancy and responds to a presence by switching to a high ouput mode

APPLICATIONS:

• Commerical exteriors, parking lots, and parking garages
