Work Principle: Sound Sensor / Voice Induction Lamp: The lamp will light up continuously for approximately 1 minute after power is connected, then turn off automatically. Please wait around 15 seconds for the sensing mode to activate. Feature: - Auto PIR motion detection or sound sensor for light on/off - Durable and energy-saving - High sensitivity, bright illumination, and low power consumption - Suitable for corridor, pathway, stair, garden, yard, etc. Specification: - Light Color: White - Connector Type: E27 - Detection Range: 5M - Detection Angle: Approximately 120 degrees - Power: 3W/5W/7W/9W/12W (Sound Sensor) - Voltage: AC200V240V Operation Instructions: 1. Install the bulb near stairs, with the bulb head facing the exit/entrance. 2. Keep the bulb away from heaters, air conditioners, refrigerators, stoves, or any locations with high temperature or strong air flow, as heat-emitting objects may trigger false activation. 3. Do not place shields, furniture, or large objects near the bulb. 4. Avoid directing the bulb toward windows to prevent interference from external heat sources, sunlight, or movement. 5. Do not install the bulb near gates or airways where airflow or motion may cause unintended activation. Troubleshooting: 1. After installation, the bulb may turn on and off automatically. This could be due to animal movement, placement in a warm area, or incorrect installation angle. 2. If the bulb turns on every 8 seconds and turns off every 30 seconds repeatedly, check for nearby movement from people or animals. Alternatively, test the bulb in another room to confirm operation.
