The California Energy Commission’s Public Interest Energy Research (PIER) Program funded the demonstration of bi-level fluorescent parking garage luminaires that combine mature fluorescent sources with occupancy-based dimming controls. The Philips Day-Brite Vaporlume fluorescent strip fixture, equipped with an optional occupancy sensor and step-dimming ballast, automatically reduces power consumption upon vacancy and increases to full power upon occupancy. Bi-level products may be combined with traditional photocontrols to maximize energy savings.
Features & Benefits:
- Bi-level light output is based on garage occupancy
- Cost-effective, mature light source is replaceable
- Can be installed in wet and humid locations
