Features. Solar charging. Use solar panel to absorb more sunlight, built-in 1200mAh 18650 lithium battery, longer conversion rate, it can prevent overheating, expansion and explosion. During the day, the solar panel absorbs light energy for charging, and the sensor light automatically turns on at night. Three lighting modes. Three lighting modes. When people come, the light turns on; when people leave, the light turns off. When people come, turns on; when people leave, the light turns on mode. Constant light mode. Infrared induction. Adopt human body infrared induction, the induction distance of sensing light is 3~5meters/117.9~196.5inch. Sensing angle, 120 degrees. Using 40 high-brightness 2835 LED patches, the brightness is sufficient. Long endurance. Built-in 1200mah battery, charging about 8H. Fully charged once, the induction lamp senses 50 times per night, and can work continuously for 3 to 4 days. Waterproof. This solar sensor light is waterproof. IP65 protection, waterproof sensor light is suitable for outdoor use, and it can turn on when it rains. Specifications. Material: ABS. Color: Black. Solar panel: monocrystalline silicon solar panel.
