Adaptive LED Parking Garage Luminaires
California's Public Interest Energy Research (PIER) program sponsored the development of adaptive parking garage luminaires that integrate intelligent controls with adaptive electronic drivers or ballasts to control light output based on garage occupancy. CLTC partnered with PIER on three demonstrations of the technology in parking garages at CSU Sacramento, CSU Long Beach and the San Marcos Civic Center Parking Garage. Luminaires operate at a reduced power during vacancy and switch to full output when occupants approach the area.
