These motion sensor lights are lighting fixtures equipped with motion sensors that detect movement within a certain range. These lights are not hardwired into the electrical system but instead operate on batteries , making them easy to install and move around as needed. They are commonly used for outdoor security lighting, illuminating pathways, or enhancing visibility in dark areas. 

SPECIFICATIONS 

1. Motion Detection Range: Look for lights with a motion detection range suitable for your needs. Some sensors can detect motion within a range of a few feet up to several dozen feet.

2. Detection Angle: Consider the angle over which the motion sensor can detect movement. A wider angle provides better coverage.

3. Brightness and Light Range: Check the brightness and coverage area of the light emitted by the fixture. Brighter lights with a broader coverage area are often preferable for outdoor security purposes.
