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.

Not sure I fully understand this. I'm assuming using a mechanical switch properly wired would not be much different than when you unplug or plug in a meanwell driver? Would you not then get a lightning flash every time you unplug the driver? If so, then it's not a good design. You'd think they would have a 'bleed' circuit in the driver similar to more conventional ballasts to prevent capacitors from discharging into a connected load. Please explain further if possible. Have you witnessed this lightning flash in a circuit so configured?
