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.
