To protect the desert ecosystem and astronomical observations, PR 402 enforces strict rules against upward light output. Fixtures must feature an Upward Light Output Ratio (ULOR) of 0%, meaning no light is emitted above the horizontal plane. Shielding and precise optics are required to eliminate light trespass into adjacent residential windows. Smart Control Systems Smart Control Systems Performance modeling must be completed
