The Xodus BL200 LED in-cabinet light is an indoor use only, battery-operated, motion sensor light. It detects when a cabinet door is opened and responds by flooding the cabinet with a bright LED light, just like the light in your refrigerator. A selection switch allows the unit to be used in automatic mode or manually as a simple on/off battery light. The BL200 features simple mounting using magnetic strips, making battery replacement easy! It requires four 'C' batteries that are not included.
