The Xenon 12V Low Voltage Accent Lights are perfect for kitchens, china cabinets, work stations, display cases, entertainment centers and more.

Simply snap together for a safe and convenient installation. No wiring needed! Just a neat, clean installation that hides under your cabinets and gives you a warm glow to light up any room. For an even lower profile, the low voltage accent lights can be recess mounted in a cabinet. What is Low Voltage? Uses small transformer to convert household electrical current (120 Volts) to low voltage (12 lots AC output with a current rating of at least 20W per puck.). Electrical codes require most transformers be mounted outside cabinetry, but low voltage wiring can run within cabinets.
