(A) Street lighting exempted. This section shall not apply to street lighting that is owned or maintained by the borough or the state.
(B) Minimization. All uses or sources, including signs, shall minimize the production of light, heat or glare that is perceptible beyond any property line of the lot on which the light, heat or glare is produced.
(C) Height of lights. No luminaire, spotlight or other light source that is within 200 feet of a dwelling or residential district shall be placed at a height exceeding 40 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.
(D) 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 or adjacent lots. No spotlight shall be directed such that the bulb itself is directly visible from a public street or dwelling.
(E) Shielding. All light sources, including signs, shall be shielded around the light source and carefully directed and placed to prevent the lighting from creating a nuisance to reasonable persons in adjacent dwellings or residentially-zoned areas, and to prevent the lighting from shining into the eyes of passing motorists.
(F) Maximum candlepower. No lighting source, including signs, shall spillover a property line in such a way as to cause an illumination of greater than the following amounts, measured on the surface at the lot line of the receiving lot or street:
(1) Three-tenths footcandle spillover at ten feet inside a residential lot line between the hours of 10:00 p.m. and 6:00 a.m.; and
(2) One footcandle spillover at 10 feet inside a residential lot line between the hours of 7:00 p.m. and 10:00 p.m.
(G) Flickering. Flashing, flickering or strobe lighting are prohibited, except for non-advertising seasonal lights between October 25 and January 12.
(H) Measurement. The maximum illumination levels of this section shall be measured with a photoelectric photometer having a spectral response similar to that of the human eye. A FOOTCANDLE is defined as a unit of measurement equaling the illumination on a surface one square foot in area where there is a distribution of light having a candlepower of one candela.
