I have 6 meanwell ELN-60-48D drivers running my leds, if I cut the AC power to the drivers I get a brief lightning show as the capacitors discharge, if I cut the DC power to the leds then no show.
I keep the AC power on all the time and use my RKE ALC to control the dimming but the leds don't completely go out (faint glow), however, installing a 5k resistor across the output terminals of the driver remedies this and the leds go completely out.

Interesting. Thanks for that. Do you suppose the lightning phenomenon harms the LEDs long/short term? Something to consider for folks planning to use this type of driver.

On both my DIY setups when the AC is cut the lights slowly fade out over 20 seconds or so, presumably as the capacitors discharge. No lightning effect.

I ended up not using the rocker switch in my original post. Thanks all.
