A. Illumination. Any illumination of a sign shall comply with the following additional regulations. 1. All externally illuminated signs that emit more than 900 lumens shall meet the exterior lighting standards per Section 744-604. 2. External light sources or lamps shall be concealed or shielded so that the light emitting element is not visible from any property line to minimize the potential for glare and unnecessary diffusion on adjacent property. 3. Efficiency. All exterior light sources shall produce at least 80 lumens per watt of energy consumed, as documented by manufacturer's specifications or the results of an independent testing laboratory. 4. The fixtures of an externally illuminated sign shall be within 12 feet of a sign face. 5. Any light source on the underside or bottom of a pump island canopy shall be fully recessed into the canopy and shall not protrude downward beyond the lowest edge. 6. The lighting of a sign shall not be directed at any vehicle travelling on a street or any pedestrian on sidewalk. 7. No sign that uses an intermittent or flashing light source to attract attention shall be permitted or maintained. Permitted digital signs operated in accordance with the standards established in Section 744-907.C are not considered flashing or animated. [image omitted; see the official code] Canopy Sign Example B. Canopy Sign Regulations. Canopies on which signs are placed shall comply with the following additional regulations. Maximum size of sign copy permitted on any canopy shall not exceed 45% of the area of the canopy plane on which it is placed. 1. Maximum projection of any canopy without support columns shall be six feet from the supporting wall. 2. Maximum distance from the top to the bottom of any canopy shall be nine feet, including any valance. 3. No canopy may extend to a point closer than two feet from any street curb or edge of an interior access drive. 4. If located over a sidewalk, no outer support columns shall be located in or obstruct the continuous, effective walkway along the public street, and the effective walkway width shall be a minimum of eight feet in the CBD districts and five feet in all other districts. C. Digital display regulations. Any digital display shall comply with the following additional regulations. 1. No digital display shall be located within 600 feet of any Protected District unless visibly obstructed from view from within that district; but in no instance may it be located within 400 feet of such a District. Measurement is made from the leading edge of the digital display sign face in a 180-degree arc from the plane of the sign face to the zoning district boundary. 2. In no instance shall digital display signs be permitted in a federally or locally designated historic district or within 600 feet of the boundary of a federally or locally designated historic district or historic site. 3. Digital displays shall only display static messages, and shall not have movement or the appearance of or the optical illusion of movement during any part of the display.

Any digital display shall be operated with systems and monitoring in place to either turn the display off or show "full black" on the display in the event of a malfunction. 7. Each digital display shall have an operational light sensing device that adjusts the brightness as ambient light conditions change. a. The brightness level for any digital display shall not operate over 464 foot candles during daytime operation. b. The brightness level for any digital display shall be calibrated for less than 0.30 foot candles above ambient light levels, as measured at 250 feet, but in no instance shall the light level, measured at any right-of-way, exceed 2.0 foot candles. 8. Light intensity of the digital display shall not cause glare.
