I experimented with a m140 module with driver in a 22mm heatsink. I hooked it up to a PWM box mod and saw the dimming effect I was looking for when I adjusted the potentiometer. Is this going to harm the diode or driver? I like the idea of this because the driver is setting the max current and the PWM is modulating the output to the driver. Is there a better way to influence the power going to the driver on a handheld?
