Adjusting artificial light levels in response to changing levels of natural
light is an important strategy used in modern lighting control systems. The
Synergy system supports both exterior and interior photocell inputs for
implementation of both open- and closed-loop lighting control strategies.
Monitoring of exterior ambient light levels provides appropriate input for
effective dusk-to-dawn or dusk-to-time control. Synergy controls also
incorporate the sophisticated logic required for interior daylight
harvesting control using fluorescent fixtures equipped with electronic
dimming ballasts.
