This motion sensor LED light bulb features a high-sensitivity PIR infrared sensor with a 120-degree detection angle that automatically detects movement within 20 feet during low-light conditions. The integrated dusk-to-dawn light sensor ensures the bulb only activates at night when motion is detected and remains off during daylight hours, providing energy-efficient operation. The bulb delivers 1000 lumens of bright cold white light at 6500K color temperature and is suitable for both indoor and outdoor use in areas such as hallways, stairs, garages, closets, porches, and entryways. Built with high-efficiency 5730 LED chips, this 9-watt bulb offers an 80-watt incandescent equivalent while consuming significantly less power. The bulb provides approximately 60 seconds of illumination once motion is detected and features an E27 standard base for easy installation. With a lifespan exceeding 50,000 hours, this motion-activated bulb reduces maintenance needs and electricity costs. For optimal performance, install the bulb with the sensor tip facing downward at a height of 10 to 13 feet. The bulb operates on AC 85-265V and functions in temperatures ranging from -20°C to 40°C, making it versatile for various environments and climates.
