E27 Socket Converter Smart PIR Motion Sensor: builtin PIR sensor detects movement and automatically turns the connected LED light bulb on and off, providing convenient and efficient lighting control. Wide Voltage Compatibility: operates on AC 100240V, allowing use in many locations without the need for adapters or converters and delivering stable performance across voltages. Intelligent Ambient Light Control: automatic switch manages lighting based on ambient light. The bulb turns on in dark or lowlight conditions and turns off when there is enough light, helping to optimize energy use. Secure and Stable Connection: reliable lamp holder design ensures a firm grip and stable connection between the adapter and the LED bulb, reducing the risk of loose connections and ensuring safe operation. LED Compatibility: designed to work with LED light bulbs when used with the E27 socket. Use scenarios Hallways and entryways: motiontriggered illumination in dark conditions for hands lighting. Closets, pantries, and storage areas: automatic lighting when you approach, turning off when not needed. Stairwells, bathrooms, and garages: suitable for lowlight environments where motion and ambientlight sensing reduce unnecessary energy consumption.
