Using an occupancy sensor can certainly be a good idea if you need it to meet energy codes like California Title 24 or IECC. Those require power reduction during evening times of vacancy or scheduled non-business hours, often achieved through motion sensors for fixtures over 40 watts. Another application can be to limit loitering by running the fixtures at a reduced rate and powering to 100% upon motion detection to offer maximum area deterrence.
