1.PWM dimmer with triac, several kinds of LED dimmer. 2.Provide custom dimmer for LED light or other lighting.

PWM Dimmer, 12 Volt, 6A (72W) Instructions & Specifications: 

This dimmer is designed to operate LED lighting, such as LED Light Strips and other light sources.  It has an integral on/off switch and provides precise dimming of light sources. 

To install, use the screw terminals and/or attached input and output wires (shaft is 1/4").  Take care to ensure the dimmer does not contact surrounding metal structure or other wiring.
