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

are you using meanwell driver?

a 5000 ohm resistor across the output of the driver will make the leds go out completely, you need a 10,000 ohm reostat to make the dimming work correctly

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.

if you cut the power to the driver you will get a lightning flash.
are you using a dimmable driver?

Yes Dimmable. What is a lightning flash please?

[Cal_stir]

if you cut power to driver, the driver will discharge its internal capacitors and the leds will give a bright flash like lightning.
the meanwell driver requires an external 10v power source for the dim circuit, normally u would use a 10k pot with a 10volt power supply to get your 0-10v for dimming, the drivers do not shut off completely but a 5k resistor across the led terminals will stop the glow and the leds will be off.
