Foot candle - Vertical Measurement (VFC): The measurement of foot candles utilizing a direct reading, portable light meter mounted in the vertical position. Glare: Light emitting from a luminaire with an intensity great enough to reduce a viewers' ability to see, cause discomfort and, in extreme cases, cause momentary blindness. Height of Luminary (including total eight): The height of a luminary is the vertical distance from the ground directly below the centerline of the luminary to the lowest direct-light-emitting part of the luminary. The total height is the height of the pole, including the base and any mounting arms or other attachments where the luminary is attached, as measured from the ground directly below the highest part of the pole or any of its attachments, to the top of the pole or luminary, whichever the case may be. Illumination System: The totality of the equipment installed to provide exterior lighting on a developed property. The illumination system includes all building, canopy, pole and ground mounted luminaries including all wiring, circuitry, and other devices installed to create exterior lighting. Lamp: The component of a luminary that produces the actual light. Lamp wattage: The amount of power of a lamp expressed in watts. Light: Direct: light emitted directly from the lamp, off a reflector or reflector diffuser, or through the refractor or diffuser lens of a luminary. Light, Indirect: Direct light that has been reflected or has scattered off of other surfaces. Light Loss Factor: A factor applied to lamps, which estimates the lumen output of a lamp sometime after installation. (For example, a lamp with an initial lumen rating of 10,000, which has a light loss factor of 0.7, is estimated to put out 7,000 lumens. A lamp with an initial lumen rating of 10,000, which has a light loss factor of 1.0, is estimated to put out 10,000 lumens.) Light Trespass: The shining of light produced by luminaries beyond the boundaries of the property on that it is located. Lumen: A unit of luminous flux. One foot-candle is one lumen per square foot. For the purpose of this Section, the lumen value is the initial lumen output rating of a lamp. Luminaries: A complete lighting unit consisting of a light source and all necessary mechanical, electrical, and decorative parts. Luminaries, Cutoff Type: A luminaries containing elements such as shields, reflectors, or refractor panels that direct and cutoff a direct view of the light source at a cutoff angle. 130 Adopted November 14, 2007
