1. Working Principle After the power is connected, the bulb of the voice-activated sensor light will stay on for about 1 minute and then automatically turn off. It is recommended to wait for about 15 seconds to enter the sensing mode. 2. Features - Supports automatic PIR human body sensing or voice activation to control the switching of the light. - Durable and energy-efficient. - High sensitivity, high brightness, and low power consumption. - Suitable for corridors, passageways, stairs, gardens, courtyards and other places. 3. Specification Parameters - Light color: White - Interface type: E27 - Detection range: 5 meters - Detection angle: Approximately 120° - Power: 3W/5W/7W/9W/12W (voice-activated sensor light) - Voltage: AC 200 - 240V 4. Operation Instructions - The bulb can be installed near the stairs. It is suggested to point the bulb head towards the entrance and exit. - The bulb should be kept away from heaters, air conditioners, refrigerators, stoves and other places with high temperature and sensitivity (objects above absolute zero may cause the bulb to light up). - Avoid placing any obstacles, furniture or large items around the bulb. - Do not point the bulb towards the window to avoid interference from hot air or white light and prevent the bulb from lighting up accidentally due to human movement. - Do not install the bulb near the door or ventilation opening. 5. Troubleshooting - The bulb may automatically turn on and off during installation, and it may also turn on automatically occasionally. Possible reasons include animals moving nearby, the bulb being pointed towards a high-temperature area, or an incorrect installation angle. - If the bulb turns on automatically every 8 seconds and turns off every 30 seconds, repeating this process continuously, at this time, you can check if there are people or animals moving around, and you can also take the bulb to another room for testing.
