Add light anywhere in your home with Energizer Push ON/OFF Puck Lights. For stylish accent lighting, place the lights underneath kitchen cabinets, shelves or bookcases, or utilize them in smaller enclosed areas, such as closets and pantries. Each puck light requires 3 AAA batteries and can be easily mounted wherever you need them. No need to hire an expensive electrician – just use the included double sided tape, or screw through the two holes in the back cover for a more permanent installation.
