LED ceiling light with PIR motion sensor, indoor surface mounted round fixture for entrance, balcony, corridor, aisle, stairs, and other areas. Human body induction technology automatically turns the light on when motion is detected within 1–5 meters, with a 120-degree sensing angle. Light remains on while motion is detected and turns off approximately 30 seconds after movement is no longer sensed. Operates only in low ambient light conditions (dusk to night). Eye-friendly design with milky white diffuser and 2835 SMD LED chips providing soft, uniform illumination with no strobe or glare. Available in 12W and 18W options, offering energy efficiency equivalent to traditional 65W and 100W fluorescent lamps, saving up to 85% on energy consumption. High-performance constant current driver ensures stable power conversion from AC to DC, reducing LED degradation and providing flicker-free lighting. Constructed with PC+ABS materials for durability. Features cool white color temperature (6000–6500K), CRI of approximately 80, and an average lifespan of 30,000 hours. Easy surface mount installation; lamp body and base designed for simple replacement.
