Wiring Question - Rheostat and Rocker switch in series, lights are still on?

[mike31154]

If you have the switch wired correctly to cut power either to the driver or to your LEDs, it should turn them off. You need to interrupt (cut) the positive lead completely & wire that through the switch. One could cut the negative but normally it's the positive that is switched. The switch will provide manual shut off only in this configuration. Another option would be to put the lights on a timer that turns them off completely when your photoperiod is done.
