72837 - 75005W Utilitech 110-Degree White Hardwired Halogen Motion-Activated Flood Light - Discontinued

• 2-head plastic fixture is ideal for security lighting

• Two 60-watt max bulbs required (not included)

• 110° motion-activated sensor detects movement up to 70 feet

PIR (passive infrared sensor) works by detecting heat in motion, a person walking by.  The motion sensor may not detect a garage door as it opens, though it may be possible for the motion sensor to detect a moving car (because of the heat from the exhaust)…however, the distance the cars are to the motion sensor may play a factor.
