The ProLine Rotary Knob LED Dimmer from Armacost Lighting works with 12 or 24-volt DC white or single color LED lighting to provide smooth and flicker-free 0-100% dimming.  Ideal for any under cabinet or accent LED lighting application.  The slim, low-profile dimmer comes with two rotary knob choices and face and mounting plates for in-wall or surface installation.  The push button on/off knobs allow you to save your preferred dimming level.   Not for use with 120-volt or multi-color LED lighting.
