Modern intelligent human infrared sensor light. Lights on when people come, and light off when people go Suitable for bedside, wardrobe, hallway, corridor, balcony, wardrobe, bathroom The small size and classic shape look good and don't take up much space Sensitive sensor and easy installation, simple to use Bright light and low power consumption for long illumination times Specifications: Name: Triangle sensor light Product size: 9.2 x 9.2 x 2.3cm Battery: 3 x AAA alkaline batteries (not included) Input voltage: 4.5V Rated power: 1.5W Sensing distance: 0-5m Sensing angle: 120 degrees Operating ambient temperature: -20 degrees Celsius to 40 degrees Celsius Working humidity: 5%-93% Light source: 10 2835 SMD SMD 6000K positive white or 3200K warm LED lights Brightness: 60 lumens Instructions for use: 1: Intelligent light sensing, when there is enough light, it will not light up whether it enters the sensing area or not 2: In places where there is not enough light when the human body enters the induction zone for activities, it lights up immediately 3: After the person leaves the induction zone, the induction light will turn off automatically in about 15 seconds 4: If the person keeps moving in the induction zone, the light will always be on 5: Please conduct the test in a dark environment, it will not light up in a bright environment 6: Please do not install the product in a humid environment, near heating pipes, air conditioning vents, and other hot and humid environments, as this may cause irregularities in operation 7: The product not only can be double-sided adhesive but also comes with a strong magnet that can be sucked on the iron cabinet at any time, a more humane design Product testing steps: Install the battery horizontally (cover the light with your hand): the light beads are normal? The induction lamp will be put into the dark box waiting for the light to go out and then will be collected into the box or cover the lampshade with the palm of your hand for 10S, the light is normal induction? Human movement sensing distance will change according to the ambient light, the darker the light the further the sensing distance, sensing distance up to 5m
