Detection function: with PIR (passive infrared sensors) motion sensor, this spotlight has a powerful infrared human body detection function, instant power on, convenience and energy saving. And the detection distance, angle, time and illumination can be set and adjusted manually. High brightness: the use of high-quality and high-efficiency SMD 2835 LEDs make this spotlight especially bright and durable. 800 lumens of light and 10w: it can replace a traditional 100w incandescent bulb, saving over 85% energy on your electricity bill. IP44 waterproof: made of die-cast aluminium and tempered glass, the spotlight is IP44 waterproof, rustproof and surface treated with high-quality electrostatic material, can be widely used in indoor and outdoor lighting projects. Perfect design: aluminium body with tempered glass diffuser for excellent light transmission. High-quality aluminium makes the lamp more durable. The reflector made of nanometer material is safe and durable. In addition, the diffusion is 1.4 times higher than traditionally LED headlights. Good heat dissipation: ultrathin design and the use of high self-heat dissipation LED 2835 ensure the best heat dissipation performance, the lighthouse can quickly lower the temperature and thus ensures the long life of the lighthouse and safety in use.
