【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.

[Easy to install]: Simply screw into any standard E26/27 light socket or fixture, no wires or additional motion detection fixtures required. 70 Watt Equivalent. This bulb will provide a bright light for you.

[Long Lifespan] : The sensor model of this smart bulb is new design that after first installed, the light motion sensor will keep lighting for 40-60 seconds, and then it enters normal model: turns on in the dark and dusk when motion is detected. This design increases the lifespan which is more than traditional motion sensor light bulb.

[Widely Application]: The radar motion senor bulb suitable for indoor, outdoor, household corridor, hallway, passage, garage, stair, step, toilets, office, coffee house, shopping center, exhibition hall, hospital etc.
