The Planning and Zoning Commission may authorize additional illumination as provided in Section 1165.08(c) hereof for lots or parcels, other than Conservation Developments, which are in excess of ten (10) acres, provided that in no instance where such special exception is granted shall the amount of light output exceed 1.0 lumen per square foot of the total illuminated area as determined by the Commission.
