§ 450-42. Control of light and glare.  


Latest version.
  • This section shall only regulate exterior lighting that spills across lot lines or onto public streets.
    A. 
    Purposes. To control outdoor lighting for safety, security, nighttime privacy and nighttime enjoyment of residential property. To minimize excessive outdoor lighting and control glare that can pose a danger to motorists. To make sure lighting is properly shielded and directed.
    B. 
    Streetlighting exempted. This section shall not apply to streetlighting that is owned, financed or maintained by the Borough or the state, to temporary emergency lighting, or to an individual porch light of a dwelling.
    C. 
    Definitions. For the purposes of this section, the following definitions shall apply:
    DIRECTLY VISIBLE
    Allowing a direct line of sight to the light source or lamp.
    FOOTCANDLE
    The amount of light striking a vertical or horizontal plane, measured in lumens per square foot. One footcandle equals one lumen per square foot.
    FULL CUTOFF LIGHT FIXTURE
    A light fixture for which no light output is emitted above 90° horizontal at any lateral angle around the fixture.
    FULLY SHIELDED LIGHT FIXTURE
    A light fixture with all light emitted from the fixture being projected below the horizontal.
    D. 
    Height of lights. No luminaire, spotlight or other light source that is within 150 feet of a lot line of an existing primarily residential use lot shall be placed at a height exceeding 25 feet above the average surrounding ground level. This limitation shall not apply to lights needed for air safety nor lights intended solely to illuminate an architectural feature of a building, nor lighting of outdoor public recreation facilities.
    E. 
    Diffused. All light sources, including signs, shall be properly diffused as needed with a translucent or similar cover to prevent exposed bulbs from being directly visible from streets, public sidewalks, dwellings or adjacent lots.
    F. 
    Shielding. All light sources, including signs, shall be installed and maintained so that they are shielded around the light source and carefully directed, aimed and placed to prevent the lighting from creating a nuisance to persons in adjacent dwellings, and to prevent the lighting from shining into the eyes of passing motorists.
    G. 
    Flickering. Flashing, flickering or strobe lighting are prohibited, except for temporary nonadvertising seasonal lights between October 25 and January 10.
    H. 
    Spillover. Exterior lighting on a lot shall not cause a spillover of light onto a residential lot after 10:00 p.m. that exceeds 0.1 horizontal footcandle at a residential lot line. Exterior lighting on a lot shall not cause a spillover of light onto a street that exceeds five footcandles.
    I. 
    Gasoline sales canopies. Any canopy over gasoline pumps shall have a maximum distance between the ground level and the underside of the canopy of 20 feet. If the ground level is sloped, or the canopy is sloped to deflect noise and soot away from neighboring properties, then a portion of the canopy may have a greater height, provided that the maximum height is 20 feet at the portion of the canopy that is closest an adjacent street. All light fixtures under the canopy shall be recessed into the canopy or screened by an extension around the bottom of the canopy so that lighting elements are not visible from another lot or street.
    J. 
    Hours of sign lighting. If an internally lit sign is within a residential district or across the street from a residential district, the lighting shall be turned off between the hours of 10:00 p.m. and 5:00 a.m. if the use is not open to the public during those hours. If such use is open to the public between 10:00 p.m. and 5:00 a.m., the lighting of the sign shall be turned off a maximum of 30 minutes after the use closes to the public.
