This is the body heat activated security light that automatically illuminates and swivels to track people as they move across your property. The unit's passive infrared sensor detects body heat from up to 40' away, automatically illuminates the four high powered LEDs, and rotates up to 240º to follow the person's movements. The sensor has a 180º detection angle and additional sensors and LEDs under its base detect and illuminate people as they walk underneath the unit. The bright white LEDs generate 600 lumens--more light than a 60-watt halogen bulb--and the included remote control allows you to adjust the light to three levels and rotate the unit. The hardwired light connects to any existing electrical box, eliminating the need to replace batteries, and mounts to a wall or under an eave with the included hardware. 9" H x 5 2/3" W x 5" D.
