TL;DR
A photocell timer is a hybrid lighting control that switches fixtures on at dusk using a light sensor, then shuts them off at a programmed hour instead of running them until dawn. The dusk-plus-set-hours scheme suits landscape and façade lighting, where all-night operation wastes energy and annoys neighbors.
