Our LED under cabinet puck lights are ultra-thin with only 0.3 inch thickness, round and almost invisible until turned on. The lights work under 12V low voltage, consuming low energy, which is safe for touch and friendly to eyes. Equipped with a wireless remote, you can control the lights and set the color/brightness/timing conveniently. To install the puck lights to a fixed location, you may use screws to fix or double-sided adhesive tapes to stick on, just needing some mins. You can install the lights to a fixed place like cabinet, furniture, showcase,etc. But more conveniently, our puck lights are not affected by location. Take it out when you use it, and save it after using at a party or a festival.
