Features: 1. RADAR DETECTION -- Adopt advance radar detecting technology, which is more sensitive and more penetrating than infrared sensors. The radar sensor light bulb can detect motion that at the other side of the wall, therefore will turn on when it detecting any object moving . (The thickness of wall should less than 8 inches). 2. MOTION SENSOR -- Motion Activated LED Light Bulb will automatically turn on when detecting motion (any moving object including pets) and automatically turn off after no motion for 30-40s. The detecting distance can reach up to 23 feet. (NOTE: After installing the light bulb, please turn on the wall switch to keep it in power, it will light on in dark.) 3. ENERGY SAVING -- The smart LED bulb only light in the dark and dusk when detecting motion and stop work at daytime. 7W/12W LED light bulb is more power efficient than traditional motion sensor bulbs, greatly helping to cut down your energy charge. This design increases the long service life. 4. WIDE APPLICATION -- The 7W/12W radar sensor night bulb is suitable to install in the bedroom, restroom, stairs, hallway, courtyard, entrance door and so on.
