C.A.P. MLC-16 and MLC-16a master lighting controllers 

The C.A.P. MLC-16 and MLC-16a represents the latest in LARGE SCALE lighting control. They control up to SIXTEEN 1000-watt HID lights from one time-clock or controller. Run 80 amp power to the MLC-16 or MLC-16a, and all of the outlets are controlled by one 120 volt “trigger cable”. You can plug the “trigger cable” into a standard 24 hour timer or lighting controller. 

The MLC-16 light controller features standard 240 volt style (NEMA 6-15) outlets, which your ballasts are plugged into. The MLC-16a uses 120 volt style (NEMA 5-15) outlets which allows for running your ballasts at 240 volts without having to change out your ballast power cords.

Each contains 4 banks of 4 lights. Each bank of 4 lights is protected by a 20 amp circuit breaker.

These light controllers need to be hardwired. We strongly recommend a licensed electrician install this unit.
