PIR Motion and Sound Sensor E27 LED Bulb Description This E27 LED bulb combines PIR motion detection and sound induction to provide hands lighting for corridors, stairs, yards and other areas where automatic on off is useful. It is energy efficient, sensitive, and designed for simple screw in installation into standard E27 sockets. Key benefits Automatic on off for convenience and safety: Lights when motion or sound is detected, eliminating the need to fumble for switches. Energy saving and durable: Low wattage options provide bright white light with minimal power consumption. Easy retrofit into existing fixtures: Standard E27 connector fits most household sockets and lamps. Reliable sensing performance: Up to 5 meter detection range and about 120 degree detection angle for consistent activation. Main features Sensing methods: PIR motion detection or sound sensor voice induction for light on and off. Startup behavior: When power is applied the bulb will light continuously for about 1 minute then turn off automatically. Wait approximately 15 seconds after power up for sensing mode to become active. Light color: White Connector type: E27 Detection range: 5 meters Detection angle: About 120 degrees Power options: 3W, 5W, 7W, 9W, 12W (sound sensor models) Voltage: AC 200V to 240V Performance: sensitivity with bright output and low power consumption Recommended installation and usage Install the bulb near the path of travel. For stair use, orient the bulb head toward the exit or entrance for detection. Keep the bulb away from heat sources such as heaters, air conditioners, refrigerators, and stoves. temperature or heated air currents can trigger the sensor. Do not place shields, large furniture, or other obstacles around the bulb that block the sensor field of view. Avoid directing the bulb toward windows where hot air currents or sunlight may cause false triggers. Do not install the bulb directly next to gates or strong air vents that cause frequent motion of curtains or foliage. Troubleshooting Occasional automatic lighting after installation can be caused by small animals, reflective heat sources, or an incorrect installation angle. Reposition the bulb and check the immediate area. If the bulb cycles on every 8 seconds and off every 30 seconds, check for continuous motion from people, pets, or moving objects. If no source is found, test the bulb in another room to isolate the issue. Allow the initial startup period to complete before judging sensor behavior. Wait about 15 seconds after the initial one minute light on period for sensing to begin. Use scenarios Stairway lighting: Install above a stair landing to provide instant illumination when someone approaches, improving visibility and reducing trip risk. Hallway or corridor: a standard bulb to have the light activate only when needed, keeping common areas lit on demand while saving energy. Outdoor porch or garden path: Use in a covered fixture to provide automatic lighting for evening arrivals or night time movement while avoiding continuous running. Compatibility and notes Fits standard E27 lamp holders and operates on AC 200V to 240V systems. Choose the wattage that matches desired brightness and fixture limits. The product is available in 3W, 5W, 7W, 9W, and 12W sound sensor models. Follow the installation recommendations to minimize false triggers and maximize sensor accuracy.
