1.Enhanced PIR Motion Inductor:Built-in sensitive PIR motion sensor, outdoor solar motion lights can detect any movement up to 26ft with 120° detection angle. Each lighting time is about 30s, and can be extended for another 30s if detected again during this period, which can satisfy your lighting demands in energy saving way.
2.High Efficient Solar Panel:Adopted monocrystalline silicon solar cells, the conversion rate reaches up to 20.5%. It has 15% electricity more than other products in the same solar light time, Made with high impact ABS lamp body that has high-temperature resistance, anti-corrosion and waterproof too,which ensures longer usage time.
3.Wider lighting Angle & Larger Coverage: Equipped with 120 led upgraded high power LEDs & 270° wide lighting angle, solar lights can provide excellent brightness and larger illumination coverage to light up a yard of 30㎡.
4.Durable IP65 Waterproof – The hmcity light is made of the IP65 technology that makes it waterproof. Durable, weather-resistant & heatproof plastic construction.
5.Quality Guaranteed: 12 Month Warranty for the solar sensor lights.the solar security lights outdoor certified by FCC, CE, ROSH, please contact us If there is any problem.
