This is a smart motion-sensing LED light that you can mount anywhere you need hands-free light. The infrared radial sensor does not require a direct line-of-sight to work- it works up to a 90-degree angle and detects motion up to 3 meters away. In addition, you can adjust the brightness and length of time the LEDs stay on. Powered by 4 AAA batteries (not included). Mount with included adhesive pad, screws (not included), or a magnetic base (not included).
