Cloudy Bay Radar Motion Sensor Ceiling Light Fixture,Time,Distance, Ambience Adjustable,10 inch,120V 15W CRI90 5000K Day Light,Damp Location, Oil Rubbed Bronze Radar Motion SensorThe light will turn on by itself when motion detected and turn off if no further motions around. The radar sensor is so sensitive that it may activate the light sometimes even with doors/walls/windows closed.It is suggested to use the ceiling light in space such as hallways,stairwells,garage where spaces are big enough. Energy Efficient  Uses only 15W of energy,equals to100W incandescent bulb. Daylight threshold With insufficient daylight,when motion detected light on; with sufficient daylight,even when motion detected light remains off. Disabling the function to let the light turn on whenever motion detected. Detection Range 4 levels of motion sensor sensitivity settings: 10%,50%,75%,100%. Maximum covering detection radius 23ft Lighting Duration 4 options of duration setting: 5 seconds,90 seconds,5 minutes,15 minutes.Light will turn off automatically after the given time if no motions around.
