      (B)   Parking lot lights that exceed four and one-half (4.5) feet in height shall be based on a photometric plan to ensure no light spillage occurs over the property line onto adjacent properties and that the parking lot is evenly lit.
   (5)   Wall mounted lighting shall not exceed a height of eight (8) feet above finished grade and shall be shielded to avoid up-lighting and concentrated hot spots (light) on the structures to which they are mounted.

   (9)   All light fixtures lawfully erected under County zoning regulations at the effective date of incorporation, annexation, or under previous zoning regulations in effect at the time of adoption of this Ordinance, or any amendment thereof, shall be deemed legal non-conforming until such time as the light fixture is replaced.
