Systems and methods of providing illumination may be provided in accordance with the invention. A lighting unit may be provided comprising a plurality of light sources, each light source of said plurality being at least partially surrounded by an optical element, and a support configured to support the light source above a surface. The light sources may be light emitting plasma sources, and the support may be a high-mast support. In some embodiments, the optical element may be a reflector containing one or more facets, directing the light toward the surface. In some configurations, each light source of said plurality may be independently controllable and/or dimmable. A lighting unit may communicate with an external controller, which may provide instructions for controlling the light sources. A lighting system may be provided with a host controlling a plurality of lighting units, which may be organized into zones. The zones, lighting units, and/or light sources may be independently controllable.
