Many of the emerging light sources used for exterior lighting, namely light-emitting diode (LED) and advanced ceramic metal halide (CMH) lamps, provide full-range dimming. Occupancy sensors have provided adaptive lighting controls in exterior parking and area lighting applications, but some applications are not compatible with sensor coverage patterns. In these scenarios, combining dimmable sources with a controller that dims based on time of day can achieve comparable energy savings to utilizing occupancy sensors. Light level reductions can be as modest as 10% or as extensive as 90%, depending on the various needs of the lighting applications.
Features & Benefits:
- Pre-programmed light output
- Adjusts to seasonal changes
- Energy savings based on end-user requirements
- Reduces operation and maintenance costs
