[Smart Light] The sensor light will automatically turn off during the day or when there is sufficient light. In the dark, the motion sensor will automatically activate the light only when human motion is detected. [Glare-free Design] The creative crescent-shaped design prevents upward light from irritating the eyes. The glare-free light in the dark will give you a more comfortable feeling and also protect your most precious health. [Easy to Use] Easy to install without complicated instructions. You can stick it anywhere with super strong 3M double-sided tape, or you can directly adsorb it on steel surfaces such as refrigerators as needed with built-in magnets. [Battery Operation] Powered by 3 AAA batteries (not included), providing coreless power. Provide effective lighting for places where there is not enough space or no electricity. [Dual Sensing Mode] Built-in light control and human infrared sensor. Light source: 2 high-brightness LED lamp beads, luminous flux: 20 lumens, beam angle: 120, PIR: 270, color rendering index: 80. Features: 1. Sensing method: light control + human infrared sensor 2. Power supply: 3 AAA dry batteries (not included) 3. Light source: 2 high-brightness LED lamp beads, luminous flux: 20lm Beam angle: 120, PIR: 270, color rendering index: 80 5. With its strong magnetism, it can be pasted or attached to the iron body with double-sided tape at any time. Function description: 1. Intelligent light sensing, when there is sufficient light, it will not light up regardless of whether it enters the sensing area. 2: When the human body enters the working area where there is insufficient light. , it lights up immediately. 3. When you leave the detection area, the sensor light will automatically turn off after about 15 seconds. 4. If you always actively sense the dark area, the light will stay on until you exit. 5. Do not install or use in a humid environment, heating duct, air conditioning outlet, etc., otherwise it may cause abnormal operation. Package Contents: 4* Motion Sensor Lights 1* User Manual Warm Tips: 1. Please check if the 3 AAA batteries are inserted in the correct direction. 2. Alkaline batteries are preferred. Your choice. They have more energy than other types of batteries. 3. This light can only turn on automatically in the dark. It will not turn on when the light sensor detects enough light. 4. If you use alkaline batteries first and then replace them with zinc-manganese dry batteries, the light may not light up. Use alkaline batteries. .
