FAQ:How does a LED dimmer switch work?
First and foremost, LEDs are not dimmed based on an increase or decrease of voltage (as is the case with their incandescent counterparts.) ... Instead, what the LED does is it creates a “dimming effect.” There are two ways to do this: pulse-width-modulation (PWM LED) and analog dimming (sans cool-sounding acronym.)
