YAVAPAI COUNTY PLANNING AND ZONING ORDINANCE Page 148 Examples of fixtures that are NOT Fully Shielded: * * * *Note: even though the lamp in these fixtures is shielded from direct view when viewed from the side or above, reflective surfaces within the fixture and or lens covers are directly visible from the side. Note for luminous (neon) tubes: when such lighting is installed under or behind a roof overhang, if the roof line or eave is not horizontal the tubing may be visible from above when viewed from the side and therefore be unshielded. Glare: is the sensation produced by a bright source within the visual field that is sufficiently brighter than the level to which the eyes are adapted to cause annoyance, discomfort, or loss of visual performance and visibility; blinding light; glare and blinding light may be dangerous to the public health and safety, as they may contribute to vehicular or other accidents. The magnitude of glare depends on such factors as the size, position, brightness of the source, and the brightness level to which the eye is adapted. Installed: means attached, or fixed in place, whether or not connected to a power source. International Dark Sky Association (IDA): an Arizona-based 501(c)(3) nonprofit organization that develops and promotes certain standards for outdoor lighting design to help protect the nighttime environment. Light Pollution: is any adverse effect of manmade light. Light Trespass: is spill light falling over property lines that illuminates adjacent grounds or buildings. Direct illumination shall be confined to the property boundaries of the source. Lumen: is the unit used to measure the actual amount of visible light, which is produced by a lamp as defined by the manufacturer. For purposes of determining compliance with this Ordinance, initial (not “maintained” or “mean”) lumen outputs of lamps (not fixtures) are the values to be considered. Examples of lumen output of typical generic incandescent bulbs (W= Watt and L= Lumen) 60 W = 840 L, 75 W = 1125 L, 100 W = 1600 L, 150 W = 2780 L, 300 W = 4620 L. Luminaire: means the complete lighting assembly, less the support assembly; a light fixture.
