Description: Feature: 1. [ DETECTION] -- Adopt advance detecting technology, which is more sensitive and more penetrating than infrared sensors. The 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 thickne of wall should le 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. 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 sensor night bulb is suitable to install in the bedroom, restroom, stairs, hallway, courtyard, entrance door and so on. Provide bright white light and prevent stumbling in the dark 5.[Compared with infrared products]: sensing distance is long, angle is wide, no dead zone, can penetrate gla, thin wood board, according to different power, can penetrate walls of different thickne, free from environment, temperature, dust, etc. influences.
