Abstract
Disclosed are lighting fixtures and lighting systems for controlling lighting based on a combination of inputs. The lighting fixtures may comprise a light source, inputs electrically connectable to sensors for sensing daylight, occupancy and environmental conditions, inputs electrically connectable to a group lighting controller output, a memory, and a lighting controller for controlling the dimming state of light sources based on received inputs. The lighting systems may comprise lighting fixtures with dimmable light sources and controllers in electrical communication with the light sources. The controllers may determine dimming states of the light sources based on group inputs and local inputs indicative of light levels, occupancy statuses, and environmental conditions near the lighting fixtures.
