1. SMART MOTION SENSOR: The motion detector works like a small electronic eyes that detect infrared waves—heat waves that radiate from moving objects. When the detector senses an object moving across its field of view—especially warmer objects such as people, animals and cars—it electronically turns on the lights. The light bulb stays on 30 Second,then the detector automatically shuts the light off unless it continues to sense movement. 2.DUSK TO DAWN: Built-in a photocell sensor, deactivates the motion sensing light bulb during the daylight hours to save energy. 3. EXCELLENT FEATURES: Super bright, gives off 500 lumen, 85% energy saving, 5W LED replace 60W halogen bulb. 4.Larger Detection Range: Make sure the sensor is pointing down within proper distance and angle. To increase the motion activation light bulb's sensitivity, you can adjust the Angle and Height of the bulb installation. The higher you hang the motion sensor light bulb, the larger detection range it achieves as the highest could be 13 feet vertically. The detection distance is around 8-10 FT in the dark by given the certain installing height and other factors. 5. WHERE TO PUT THEM? :For best effectiveness, position a motion sensor light to cover the walks leading to your front and back doors and the driveway, If improved security is a priority, position the motion sensored lights to cover all the approaches to your house, including fence gates, the patio door, the darker areas of your yard, and around trees and bushes. backyard, porch, patio, garage, basement, hospital, office, hotel, closet, balcony, gate, etc.
