(3) Lighting Amount: Lighting amounts may exceed the limit listed in Subsection C.2.j for the area of the display only. However, when the proposed lumens per acre exceed the limits of Subsection C.2.j the installation shall be designed to achieve no greater than the minimum illuminance levels for the activity as recommended by the Illuminating Engineering Society of North America (IESNA). If IESNA has more than one applicable recommended practice, then the lowest figure shall apply. Street lighting is exempt from the total lumen count for a given property. (4) Off-Site Spill: The installation shall limit off-site spill (off the parcel containing the display lot) to a maximum of 0.5 fc at any location on any non-residential property, and 0.05 fc at any location on any residential property, as measurable from any orientation of the measuring device. (5) Curfew: Outdoor Display Lot lighting exceeding the lumens per acre cap of Subsection C.2.j shall be turned off at 10:00 p.m. or within thirty (30) minutes after closing of the business or activity whichever is later and once off remain off during non-business hours. Lighting in the Outdoor Display Lot after this time shall be limited to Class 2 lighting, and shall conform to all restrictions of this Ordinance applicable for this class, including the lumens per acre caps in Subsection C.2.j and lamp type standards of Subsection C.1.

(2) Shielding: All luminaires shall be flush with the lower surface of canopies and utilize flat glass or plastic covers. (3) Canopy Lighting Amount: The total light output used for illuminating service station canopies, defined as the sum of under-canopy initial bare- lamp outputs in lumens, shall not exceed sixty (60) lumens per square foot of canopy. All lighting mounted under the canopy, except internally illuminated signs, shall be included in the total. (4) Inclusion Toward Total Outdoor Light Output: Twenty-five percent (25%) of the lumen output of all lamps mounted within or under a canopy, except internally illuminated signs, is included in the lumen caps in Subsection C.2.j.
