Controls

With the introduction of LED Lumi-lock, also comes the benefit of controls which allow you to dim light at will. The two controls being offered are the (C1) Logic based control, and our simpler (C2) On-Off control. Both controls allow the customer to set the system for a 50% reduction in wattage on the L55 (5500 lm) fixtures for whatever time spans the customer chooses.

  • (C1) is a logic control device at the fixtures location that will have the ability to use switches, relays, or lights sensors to control when and for how long the 50% dimming is active.
  • (C2) is simple On-Off control that will rely on a 4-wire system being brought to the fixture with the controls (time clocks, or a combination of a time clock and photocell) at the panel box to control the 50% dimming.
