【PIR Motion Sensor & Light Sensor Technology】The PIR infrared motion sensor light bulb is sensitive to human or animal’s skin temperature. When the 2 sensors activated by the movement and the light intensity is less than 6 lux(dusk to dawn), bulb will turn on automatically. The bulb will switch to energy saving sleep mode in the daytime as the light intensity raises up to 6lux, under which circumstance bulb will not be turned on.

【30s Delay Time & Energy Saving】When 2 sensors are activated, the motion sensor light bulb will stay on about 30 seconds when motion ceased. if there are continuous movements in the detecting range(distance: 16-20ft, angle: 120°), the smart light bulb stays on, it’s brightness can reach to 1000lm, perfect for replacing a traditional 120W halogen bulb with 90% energy saving.

【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 16-23 feet given the certain installing height and other factors.

【Recommend Applications】This motion sensor light bulb compatible with any standard E26 socket, These motion activated light bulbs only light up in the detective range at night or in dark environment, energy-saving, environment protecting and long life, can be use in stairs, hallway, bathroom, front door, storage room, garage, closet, balcony, gate and so on.
