Description:Function:1. [radar detection]-Adopt advanced radar detection technology, which is more sensitive and more penetrating than infrared sensors. The bulb radar sensor can detect the movement that on the other side of the wall, which is why it turns on when it detects the movement of any object. (The wall thickness should be less than 8 inches).2. [motion sensor]-The motion sensor LED bulb will automatically turn on when motion is detected (any moving object, including pets), and automatically turn off when there is no movement for 30-40 seconds. The detection distance can reach up to 23 feet. (Note: After installing the bulb, turn on the wall mount switch to keep it in power, it will light up in the dark.)3. [energy saving]--Smart LED bulbs only light up in the dark and dusk when detecting motion and stopping work during the day. The LED bulb is more powerful efficient than traditional motion sensor bulbs, which greatly helps to reduce the energy charge. This design increases the long service life.4. [Wide Application]-The night light bulb radar sensor is suitable to be installed in the bedroom, toilet, stairs, hallway, courtyard, front door and so on. Provide a bright white bulb and prevent tripping in the dark5. [Compared with infrared products]: the radar detection distance is long, the angle is wide, there is no dead zone, can penetrate through glass, thin wood board, according to different power, can penetrate walls of different thickness, free from the environment, temperature, etc. Specifications:Specification:LED Bulb Type: Bubble BulbBasic Type: E27Certification: CCCotions: BedroomLuminous Flux: 1000 - 1999 LumensBeam Angle (°): 180°Power Tolerance: 1%Working Voltage: AC 85-265VChip LED Model: 2835Detection Distance: 3-8 metersDelay Time: About 20 SecondsColor Temperature: Cool White (5500-7000K)Average Lifespan (Hours): 50000Shape: GroundNote: This product has photosensitive elements that are normal during the day.
