Abstract
An apparatus and method of retrofitting a light fixture are disclosed. One method includes interfacing a retrofit controller with a dimming ballast of the light fixture, connecting the retrofit controller to at least one sensor, and connecting the retrofit controller to a power supply. Another embodiment includes a light fixture retrofit controller and a separate sensor unit. The combination of the retrofit controller and a separate sensor unit are operative to provide power and dimming control of a dimming ballast of an existing light fixture. The dimming control is base on at least one of a signal sensed by the separate sensor unit and control information received from a network.
