All exterior lighting, including light emitted from security systems, shall be shielded or use a hood and lens that cast light downward so as to ensure no light is cast onto adjacent properties nor upward into the night sky. If the lighting mechanism does not utilize a hood or lens, lighting fixtures shall be fully shielded in such a manner that all light emitted directly by the lamp or diffusing element, or indirectly by reflection or refraction, is projected below the horizontal plane through the lowest light-emitting part.
