Manage that light
The Light Manager for Mark VII dimming ballasts provides precise control of light levels while taking advantage of external daylight. The system is ideal for any size commercial lighting installation where visual comfort, productivity and energy savings are desired. The system monitors daylight and readjusts lighting to the user-programmed level. Operated by a wall switch with on/off, dim/bright and programming functions for six control modes, the system can use any of the manufacturer's occupancy sensors to save more energy.
