Smart E27 PIR Motion Sensor Lamp Holder — automatic on/off for LED lights Why you need it Hands-free lighting: the built-in PIR motion sensor turns connected LED bulbs on when it detects movement and off when no motion is present, removing the need to fumble for switches. Energy and cost savings: automatic shutoff reduces wasted runtime for lights you forget to turn off. Simple upgrade: convert an existing E27 lamp socket into a motion-activated fixture without replacing wiring or the whole fixture. Key features and benefits Intelligent motion sensing: integrated passive infrared (PIR) sensor reliably detects human motion and triggers the connected LED light automatically. E27 socket adapter: screws into standard E27 lamp holders and accepts E27 LED bulbs, making installation fast and reversible. Wide voltage compatibility: supports AC 110V and AC 220V power supplies for use in regions with either voltage. Automatic switching: built-in switch function powers the LED on when motion is detected and turns it off when motion stops, helping extend bulb life. Durable, compact construction: made from sturdy PC material for long-lasting use; compact dimensions (5 x 5.7 x 5.7 cm) fit most lamp fixtures without obstructing the fixture or bulb. Broad LED compatibility: designed to work with a wide range of LED bulbs that use an E27 base. Practical applications Hallways and staircases: installs in existing ceiling or wall fixtures to provide instant light when someone passes through, improving safety without running lights continuously. Garages, basements and storage rooms: activates lighting only when you enter, avoiding wasted energy in intermittently used spaces. Closets, utility rooms and porches: adds motion-activated convenience to small areas where switches are inconvenient or out of reach. What’s included and installation notes E27 PIR sensor adapter (built-in PIR sensor, E27 socket) Installation is straightforward: screw the adapter into your existing E27 lamp holder, then screw an E27 LED bulb into the adapter. Compatible with AC 110V and AC 220V systems. Constructed from PC material; compact 5 x 5.7 x 5.7 cm size for easy fit in most fixtures. Reliable, easy-to-install solution for motion-activated LED lighting that saves energy, improves convenience, and fits standard E27 fixtures.
