Except as otherwise provided, or in subsection 8-3-1B of this chapter, all outdoor luminaires shall be shielded in such a manner that light rays emitted by the luminaire, whether directly from the lamp or indirectly from the luminaire, are restricted to regions below an angle fifteen degrees (15°) beneath the horizontal plane running through the lowest point on the luminaire where light is emitted. No significant intensity of light shall be emitted from the luminaire horizontally, nor above the horizon, nor above the region defined above. In general, all outdoor lighting shall be downward directed, except where specified otherwise in this chapter. (Ord. 331, 3-8-2005)
