Easy to Install # Ready to use, with everything you need for setting up the lighting system. Screws or double sided adhesive stickers are included in the package and optional for mounting the pucks. Touch Sensitive Dimmable # With the inline on/off touch dimmer switch, the puck lights can be dimmed from 0 to 100 full brightness smoothly. Short touch: On and Off. Long touch: Dimming. Note: can not use existing wall dimmer switchs for dimming! Low Profile Light Puck # The height of the puck light is approximately 0.3inch. As a result, the pucks can be hidden well under a cabinet. They can hardly been seen unless the lights turned on.
