E27 Motion Sensor Light Socket URZ3149-1 — 360° PIR Twilight Sensor for E27 Lamps

The E27 Motion Sensor Light Socket URZ3149-1 is a screw-in adapter designed to convert standard E27 lamp fittings into motion- and light-sensitive fixtures. The unit integrates a 360° passive infrared (PIR) motion detector together with a twilight sensor so that connected E27 bulbs switch on automatically when ambient light is low and motion is detected. The socket is intended for indoor and sheltered outdoor applications such as corridors, stairways, garages and covered porches, providing energy savings and hands-free lighting control.

Advantages

The integrated 360° PIR sensor provides wide-area detection without additional wiring, while the twilight sensor prevents lights from triggering during daylight. Installation is simple: the adapter screws into an existing E27 socket and the bulb screws into the adapter. The device supports automatic off-timing after a period without motion to reduce energy use. Its compact form factor keeps the luminaire appearance largely unchanged and enables quick retrofit of ordinary lamps into automated lighting.

Suitable for

• Corridors and hallways
• Stairways and landings
• Garages and utility rooms
• Covered outdoor entryways and porches
• Storage areas and basements

Key specifications

• Socket type: E27 screw-in adapter compatible with standard E27 bulbs
• Detection: 360° passive infrared (PIR) motion detection
• Light control: built-in twilight sensor to prevent activation in bright conditions
• Operation: automatic ON when motion detected in low light, automatic OFF after set timeout
• Mounting: fits existing E27 fixtures without additional wiring
• Recommended locations: indoor and sheltered outdoor areas (not fully exposed to weather)

How to use

To install, screw the motion sensor socket into a standard E27 lamp holder, then screw the chosen E27 bulb into the adapter. Ensure the sensor has a clear line of sight to the area where motion detection is required and is positioned out of direct sunlight. The device operates automatically: when ambient light is below the twilight threshold and motion is detected within its coverage, the connected bulb switches on; it switches off after the absence of motion for the preset time. Use bulbs compatible with the socket type and within the lamp’s rated power limits.

Usage recommendations

Place the sensor at a height and orientation that maximizes coverage for walking paths and avoids pointing directly at heat sources or moving objects such as trees or air vents. For sheltered outdoor use, ensure the fixture is protected from direct rain and excessive moisture. Choose LED or energy-saving bulbs compatible with E27 fittings to optimize energy savings and longevity.
