Sec. 146-918. Lighting
(A) Intent. Vehicular and pedestrian lighting shall be provided throughout all vehicular and pedestrian circulation areas to promote safety and walkability.
(B) Standards Applicable to All Development
1. Except in Low Density Residential subareas, sidewalks, internal pedestrian paths, and bicycle paths shall be lit with full cutoff lighting fixtures no more than 16 feet tall and providing consistent illumination of at least one footcandle on the walking surface
2. On-site streets and parking areas shall be lit with full cutoff type lighting fixtures no more than 25 feet tall. Fixtures shall be downcast type.
3. Lighting along public street and landscaped areas of a specific development or activity center shall be of a recognizably unified design
4. Lighting sources shall be color-correct types such as Halogen or metal halide, and light types of limited spectral emission, such as low pressure sodium or mercury vapor lights, are prohibited even in service areas
5. Private and security lighting shall not cause glare above a level of 4 feet onto adjacent properties
Signage
5.Illumination
a Sign lighting shall be shielded to prevent glare onto adjacent public rights-of-way and adjacent properties. Sign lighting shall be directed so that light does not stray above the light source horizontally. Lighting shall be steady and even over the entire sign face.
b. All lighting fixtures and elements shall be maintained in good working condition. Exposed bulbs shall not exceed 15 watts in power
c. Signs shall be illuminated only during the times the establishment displaying the sign is operating or open for business.
d. Where sign faces are internally lit, the area of all the letters and numbers, plus the entire area of illuminated background, shall be counted as sign area for the purposes of meeting the Aurora Sign Code.
Sec. 146-922. Special Design Standards for Regional Activity Centers
(N) Lighting
1. Standards Applicable to All Development in an RAC. Civic buildings and buildings or portions of buildings over 100 feet tall shall use floodlighting to emphasize the height of the building at night. Such lighting shall be projected onto building faces from a position above the first floor so not to create glare at the level of pedestrians or public rights-of-way
2. Standards Applicable to Main Street Sites
a. Lighting fixtures on the Main Street shall have a maximum height of 12 feet and shall be located in the required 8-foot-wide tree lawn.
b. Lighting fixtures shall be spaced a maximum of 36 feet apart from one another.
Lighting fixtures on the Main Street shall have a minimum light intensity of 1 lumen per square foot and a maximum intensity of 2 lumens per square foot.

Sec. 146-1015. Lighting
(A) Intent. Vehicular and pedestrian lighting shall be provided throughout all vehicular and pedestrian circulation areas to promote safety and walkability.
(B) Standards Applicable to All Development
1. Sidewalks, internal pedestrian paths, and bicycle paths shall be lit with full cutoff lighting fixtures no more than 16 feet tall, and providing consistent illumination of at least one footcandle on the walking surface.
2. In the Medium Density Residential Subarea, on-site streets and parking areas shall be lit with full cutoff type lighting fixtures no more than 25 feet tall. Fixtures shall be downcast type
3. Lighting along public streets and landscaped areas of a specific development or activity center shall be of a recognizably unified design.
4. Lighting sources shall be color-correct types such as halogen or metal halide, and light types of limited spectral emission, such as low pressure sodium or mercury vapor lights, are prohibited even in service areas.
5. Private and security lighting shall not cause glare above a level of 4 feet onto adjacent properties
Signage
(E) Illumination
1. Sign lighting shall be shielded to prevent glare onto adjacent public rights-of-way and adjacent properties. Sign lighting shall be directed so that light does not stray above the light source horizontally. Lighting shall be steady and even over the entire sign face.
2. All lighting fixtures and elements shall be maintained in good working condition. Exposed bulbs shall not exceed 15 watts in power.
3. Signs shall be illuminated only during the times the establishment displaying the sign is operating or open for business.
4. Where sign faces are internally lit, the area of all the letters and numbers, plus the entire area of illuminated background, shall be counted as sign area for the purposes of meeting the Aurora Sign Code.
Building Codes – Supplemental Regulations – Parking Area Design
H) Lighting. Parking areas shall be illuminated as unobtrusively as possible to meet the functional needs of safe circulation and of protecting people and property. To accomplish these purposes, lighting of parking areas shall meet or exceed the following standards as demonstrated in the parking plan:
1. Shielding of lights in commercial parking areas. Light sources shall be of a full cut-off luminaire type, and concealed or shielded to the maximum extent possible to minimize the potential for glare and unnecessary diffusion on adjacent property. Lighting fixtures for canopies or similar structures shall be recessed or flush-mounted and equipped with flat lenses. For any fixtures adjacent to a residential use or residentially zoned lot, the source of light shall be shielded from sight. This requirement for shielding applies to all light fixtures including security lighting. However, incandescent light sources of 100 watts or less or other light sources of 60 watts or less (gaseous discharge) do not have to be shielded provided they are located at least 150 feet from the property line of a residential district.
2. Illuminance level. Maintained average illuminance values in paved, commercial parking areas and multi-family developments shall be no less than two foot-candles. Where adjacent to residential uses, maintained average illuminance shall not exceed 0.5 (one-half) foot-candle at ten feet beyond the property line except where adjacent to walkways, driveways, public and private streets. Illuminance shall be measured using only the light produced on-site. The acceptable uniformity ratio for lighted areas shall be in conformance with recommended ranges adopted by the Illumination Engineering Society of North America (IESNA) for low, medium, and high activity areas.
3. Hours of lighting. All parking luminaires, except those required for security, shall be extinguished within one hour after the end of business hours and remain extinguished until one hour before the commencement of business hours. However, for reasons of security, a maximum of 25 percent of the total luminaires used for parking lot illumination may remain in operation during such period. Parking area lighting during off-business hours need not conform to the otherwise applicable average-to-minimum uniformity ratio
4. Light color. Light sources shall produce accurate color rendition and shall be compatible with adjacent light sources. Metal halide and high-pressure sodium light sources have high to fair color rendition and are permitted light sources
5. Pole location. Poles shall be located outside of vehicular circulation areas and off-street parking spaces to the extent possible. In no case shall a pole encroach more than six inches into any required parking space. Location of poles shall not interfere with door opening or vehicular movement
6. Style and color. Light poles and fixtures shall be consistent with the style and character of architecture proposed on the site
7. Height. Light poles shall not exceed 30 feet in height. Pedestrian scale standards, of 12 to 16 feet in height, are recommended for use wherever reasonably practicable. In industrial zone districts, light poles located at least 750 feet from residentially zoned properties may be up to 40 feet in height.
