§ 161.254 SIGN ILLUMINATION STANDARDS.
   Signs may be illuminated consistent with the following standards:
   (A)   A sign in any zoning district may be illuminated at night except as provided within § 161.249 as to single family and two family residential sites and individual dwelling units of multi-family dwelling complex or of a manufactured home park, or except as provided by another ordinance or provision of law. Signs that are illuminated at night may not exceed a maximum luminance level of seven hundred fifty (750) cd/m² or Nits, regardless of the method of illumination.
   (B)   Signs that have external illumination, whether the lighting is mounted above or below the sign face or panel, shall have lighting fixtures or luminaires that are fully shielded.
   (C)   All illuminated signs must comply with the maximum luminance level of seven hundred fifty (750) cd/m² or Nits at least one-half hour before Apparent Sunset, as determined by the National Oceanic and Atmospheric Administration (NOAA), US Department of Commerce, for the specific geographic location and date. All illuminated signs must comply with this maximum luminance level throughout the night, if the sign is energized, until Apparent Sunrise, as determined by the NOAA, at which time the sign may resume luminance levels appropriate for daylight conditions, when required or appropriate.
