The LED Touch Dimmer Switch provides smooth, full range dimming and on/off control of white LED lighting with a convenient touch sensor. A short tap on the touch pad turns lights on and off, and a long press adjusts brightness from dim to bright. Create the perfect ambiance in your home at your preferred brightness and enjoy the gradual, soft on/off lighting and stepless 0-100% dimming. Dimming helps extend the life of your LED lights, uses less energy, and reduces eye strain. Designed for use with Armacost Lighting's white or single-color LED lights and 12-volt or 24-volt DC constant voltage electronic power supplies. Not for use with multicolor LEDs or 120-volt lighting fixtures.
