For any commercial or industrial use, outdoor lighting must be shielded with full cut-off fixtures to eliminate direct illumination to any adjacent country, residential, apartment, apartment mixed-use, or resort zoning district. For a rooftop gathering space that is not enclosed, outdoor lighting must be shielded, with full cut-off fixtures to eliminate direct illumination beyond the rooftop gathering space.
