Motion sensor: While traditional night lights stay on all night regardless if anyone is in the room, the Philips SpotOn only turns on if motion is detected. Leaving the light off to save energy when it’s not needed.
Motion & Photo Sensors: The Datexx ZenLight LED uses photo sensors to emit a dim glow in dark settings and a bright light when motion is detected.
