## Abstract

A lighting system configured for daylight emulation. The system includes a plurality of light sources for generating a daylight-emulating output light spectrum. The system also includes a controller for dynamically controlling at least one of the intensity, directionality and color temperature to emulate sun position for at least one of a geography and time of day. The system further includes a networking facility that facilitates data communication with at least one external resource.
