A. Intensity.
1. The maximum light level of any light fixture shall not exceed 0.5 foot-candles measured at the property line of any Residential District and 3.0 foot-candles measured at the public right-of-way.
2. Lighting must not be oriented so as to direct glare or excessive illumination onto adjacent properties, streets, or sidewalks.
3. The maximum color temperature rating for LED lights shall be 4,300 degrees Kelvin.
B. Light fixture type. All light fixtures to be installed on a permanent basis shall consist of full cutoff and cutoff fixtures, unless otherwise stipulated by this chapter. Full cutoff fixtures shall be utilized where the light fixture has more than a 1,250 lumen output, unless as otherwise stipulated by this section. Lighting fixtures to be utilized on a temporary basis and as permitted through Sec. 6-4.2(8) shall be exempt from this requirement.
C. Accent and facade lighting.
1. Lighting fixtures shall be selected, located, aimed, and shielded so that direct illumination is focused exclusively on the building facade, plantings or other intended site features and away from adjoining properties and the street right-of-way.
2. All wall pack fixtures must be full cutoff fixtures.
3. Only lighting used to accent architectural features, landscaping or art may be directed upward, provided that the fixture is located, aimed, or shielded to minimize light spill into the night sky.
4. The Planning and Development Director may waive this requirement in cases where it is impractical.
D. Dusk-to-dawn utility/security lights.
1. Light fixture must either be aimed down at least 45 degrees from vertical or the front of the fixture must be shielded so that no portion of the light bulb extends below the bottom edge of the shield.
2. Any light fixture located within 50 feet of a public right-of-way, with a side-to-side horizontal aiming tolerance not to exceed 15 degrees.
Overhead View
3. All light fixtures emitting 1,000 or more lumens must be aimed at least 60 degrees down from the horizontal or shielded so that the main beam is not visible from adjacent properties or the street right-of-way.
E. Outdoor display, parking, and pedestrian areas.
1. Light fixtures within outdoor display and parking areas shall not exceed a height of 30 feet from adjacent grade.
2. Light fixtures within pedestrian areas or within 50 feet of a residential district shall not exceed a height of 15 feet from adjacent grade.
3. Light fixtnres in outdoor display and parking area must be full cut-off. In other areas, light fixtures with more than 2,000 lumens must be full cutoff unless they meet the following:
a. Non-cutoff fixtures can be used when the maximum initial lumens generated by each fixture does not exceed 9,500 lumens;
b. If the unshielded fixture has a metal halide, fluorescent, induction, white high pressure sodium and color-corrected high pressure sodium lamp, the outer lamp envelope must be coated with an internal white frosting to diffuse light;
c. All metal halide fixtures equipped with a medium base socket must use either an internal refractive lens or a wide-body refractive globe; or
d. All non-cutoff fixture open-bottom lights must be equipped with full cut-off fixture shields.
F. Recreational Fields and Outdoor Performance Areas.
1. The mounting height of lighting fixtures shall not exceed 80 feet from adjacent grade unless approved as a special use permit in accordance with Sec. 3-7.1.
2. AH fixtures must be equipped with a glare control package, including louvers, shields or similar devices. The fixtures must be aimed so that their beams are directed and fall within the primary playing or performance area.
3. No illumination, when measured from the property line, shall exceed 0.4 foot-candle of lighting.
4. Lights within 100 feet of a residential district shall not be illuminated between the hours of 11:00 p.m. and 6:00 a.m.
5. In all other districts, the hours of operation for the lighting system shall not exceed one (1) hour after the end of the game or event.
G. Signs. Lighting fixtures illuminating signs must meet the standards of Sec. 6-2.7.
H. Vehicular canopies. Lighting under vehicular canopies shall be less than 30 foot-candles and be designed to prevent glare off-site. Acceptable lighting designs include the following:
1. Recessed fixture incorporating a lens cover that is either recessed or flush with the bottom surface of the canopy;
2. Light fixture incorporating shields or is shielded by the edge of the canopy itself, so that light is restrained to 5 degrees or more below the horizontal plane;
3. Surface mounted fixture incorporating a flat glass that provides a cutoff design or shielded light distribution;
4. Surface mounted fixture measuring no more than 2 feet by 2 feet, with a lens cover that contains at least 2% white fill diffusion material; or
5. Indirect lighting where light beamed upward and then reflected down from the underside of the canopy, provided the fixture is shielded so that direct illumination is focused exclusively on the underside of the canopy.
