A dimmer module works by adjusting the amount of electrical current flowing to a light source, thereby controlling its brightness. It typically uses a method called phase-cutting, where it chops up the AC waveform to reduce the power delivered to the light. This can be done through leading-edge dimming, which cuts the beginning of the waveform, or trailing-edge dimming, which cuts the end, depending on the type of light and dimmer compatibility.
