Editor's Note: Appendix A is included as an attachment to this chapter.
Light intensity and uniformity.
Commercial district, public district and industrial district lighting zones. During permitted hours of operation as defined within this Part 20, outdoor lighting on any zoning lot in a commercial district, public district or industrial district lighting zone shall meet the following requirements for light level as measured in the plane of the illuminated surface:
Digital outdoor display. The digital outdoor display shall be equipped with a light sensor which shall automatically adjust the luminance of the sign in response to the level of the outdoor lighting in a range between 40 nits during the nighttime hours and 5,000 nits during the daytime hours. Brightness must be measured from the brightest element of the sign's face. The applicant shall provide written certification from the sign manufacturer that the light intensity has been factory pre-set so that it shall not exceed the luminance levels for day and night. Daylight hours are defined as dawn until dusk.
Light direction and control. Any luminaire which is used for uplighting on any zoning lot in a residential district, commercial district, public district or industrial district lighting zone shall have the necessary shielding and/or beam-angle control and/or shall be aimed to substantially confine the directed light to the object intending to be illuminated. Uplighting shall only be permitted for landscape lighting, architectural lighting, flag lighting, and lighting of ground-mounted signs that are not internally illuminated. Uplighting applications shall meet the following requirements:
Residential district lighting zones.
Any luminaire with a light output exceeding 1,100 lumens which is used for outdoor lighting on any zoning lot in a residential district lighting zone shall have the necessary shielding and/or beam-angle control and/or shall be aimed so that the direction of all directly emitted light is at or below horizontal. Any luminaire output less than what is listed above does not require shielding. If a motion-activated sensor that illuminates the luminaire for no more than five minutes upon activation is used, however, said luminaire shall have a light output of up to 2,200 lumens (or incandescent bulb of 150 watts).
Any luminaire with a light output exceeding 2,200 lumens (or incandescent bulb of 150 watts) which is used for outdoor lighting on any zoning lot in a residential district lighting zone shall have the necessary shielding and/or beam-angle control and/or shall be aimed so that the light source is not visible along any property line, as viewed at a height of 36 inches above grade.
Commercial district, public district or industrial district lighting zones. Except as otherwise stated herein, any luminaire on any zoning lot in a commercial district, public district or industrial district lighting zone which emits light directed at a building, sign, billboard, or other outdoor feature shall be located at or above the top of said object and be aimed and controlled so that the direction of all emitted light is at or below horizontal and the directed light is substantially confined to the object intended to be illuminated.
Except for street lighting, light emitted from outdoor lighting on any zoning lot shall not cause the light level along any property line, as measured at a height of 36 inches above grade in a plane at any angle of inclination, to exceed the following limits:
The light level at any property used for governmental, recreational and public purposes in all zoning districts shall not exceed 0.1 footcandle at all property lines.
Permitted hours for outdoor lighting.
