AtLite SL2 StairLite 2 Motion Sensor Emergency Light

*Updated 2021* The StairLite 2 is designed to satisfy all stairwell lighting requirements in one easy-to-install package. The StairLite 2 is a surface-mounted, two-lamp fluorescent lighting fixture that incorporates an integrally mounted ultrasonic motion detector, a system display panel, and an optional battery backup. Either one or both lamps can be controlled by the motion sensor. Bi-level lamp operation is standard so that one lamp will remain on constantly for security and the motion detector will activate the second lamp as needed to significantly reduce the operating cost.
