Day-Night Detection: Built-in infrared sensor intelligently distinguishes between day and night, activating the light only in low-light conditions. When no motion is detected, it automatically turns off after about , reducing unnecessary power consumption while ensuring hands-free, convenient lighting control. Wide Voltage Compatibility: Designed for wide-range AC 85-265V input, this motion sensor switch works seamlessly with most LED and ‑saving lamps up to a 40W load. Stable performance helps prevent flickering, offering consistent, efficient lighting for both residential and light commercial applications. Tool-Free Installation: Features a standard 20 mm diameter body suitable for both wall and ceiling mounting, enabling easy integration into existing junction boxes or panels. Simple plug‑and‑play wiring allows fast setup without special tools, making it ideal for DIY users and quick retrofit projects. PIR Tech: Advanced passive infrared technology provides a 120° conical detection angle with a reliable sensing range of approximately 3-5 meters. The sensor quickly responds to human movement signals, delivering instant illumination without delay and enhancing safety in dark or low-visibility areas. Multi-Scenario Use: Perfect for corridors, bathrooms, garages, warehouses, and advertising lightboxes, providing automatic lighting in frequently used spaces. Waterproof construction and components support reliable operation in harsh environments from -20℃ to +40℃, indoors or in sheltered outdoor areas., Weight: 2.645547144 Pounds, Manufacturer: Ehwisbe
