 PIR Motion Sensor with Concealed LED Light is a lighting device that combines a motion sensor and an LED light. Here are some details about this product:

1. Function: The PIR Motion Sensor is designed to detect motion in its vicinity and automatically turn on the concealed LED light when motion is detected. It is commonly used as a security feature or for convenience in areas such as hallways, staircases, or outdoor spaces.
2. Motion Sensor: The PIR (Passive Infrared) motion sensor detects changes in infrared radiation emitted by objects in its detection range. When it senses motion, it sends a signal to the LED light, triggering it to turn on. This helps to conserve energy by only activating the light when needed.
3. LED Light: The  PIR Motion Sensor features a concealed LED light with a power rating of 7 watts. The LED technology offers energy efficiency, longevity, and good illumination.
