ANSIShall mean the American National Standards Institute.
ANSI/IES LIGHTING STANDARDSShall mean applicable outdoor lighting standards and metrics include but are not limited to: 1) RP-2: outdoor retail spaces, 2) RP-6: outdoor sports and recreational areas, 3) RP-7: outdoor industrial areas, 4) RP-8: roadway and parking facilities, 5) RP-40: port terminals, 6) RP-43: outdoor pedestrian areas.
CANDELA (CD)Shall mean the unit of measure for luminous intensity.
CCT (CORRELATED COLOR TEMPERATURE)Shall mean the measured color appearance of light emitted by a light source described using a nominal value stated in kelvins (K). Lower CCTs (1800 K to 2200 K) appear very warm or amber. Medium CCTs (2700 K to 3000 K) appear "warm white," similar to standard incandescent bulbs. High CCTs (4000 K and higher) appear "cool white" or "blue."
DISTRIBUTIONShall mean the way light is spread across a given area.
FOOTCANDLEShall mean the unit of measure expressing the quantity of light received on a surface. One footcandle is the illuminance produced by a candle on a surface one foot square from a distance of one foot.
FULLY SHIELDEDShall mean a luminaire designed or shielded in such a manner that no light is emitted, either directly or indirectly, at or above a horizontal plane running through the lowest light-emitting part of the luminaire (has a U0 Uplight Rating).
GLAREShall mean lighting entering the eye directly from luminaires or indirectly from reflective surfaces that causes visual discomfort or reduced visibility.
IES (ILLUMINATING ENGINEERING SOCIETY)Shall mean an ANSI-recognized Standards Development Organization. ANSI/IES Recommended Practices are universally recognized as authoritative references for lighting applications.
ILLUMINANCEShall mean measured in lux or footcandles, the total luminous flux incident at a point on a surface (light level on a surface).
LIGHT LEVELShall mean the maintained luminance or illuminance value.
LIGHT POLLUTIONShall mean artificial light traveling into areas where it is not needed or wanted. This can be in the form of light trespass, glare, or atmospheric sky glow.
LIGHT TRESPASSShall mean illumination past property lines without permission. Unless specified otherwise, light trespass limits are measured at any location along a property line both horizontally at the ground plane facing upward and vertically at 1.5 meters (five feet) above grade with the meter aimed toward the light source in question.
LIGHTING EQUIPMENTShall mean equipment specifically intended to provide gas or electric illumination, including, but not limited to, lamp(s), luminaire(s), ballast(s), poles, posts, lens(s), and related structures, electrical wiring, and other necessary or auxiliary components.
LUMENShall mean the unit of measure used to quantify the amount of light produced by a lamp or emitted from a luminaire (as distinct from "watt," a measure of power consumption). One lumen per square foot is equivalent to one footcandle. In terms of SI units, one lumen per square foot is approximately equivalent to 10.76 lux.
LUMINAIREShall mean a complete lighting unit, including the light source, housing, optics, electronics, and other necessary components for the purpose of providing outdoor illumination.
LUMINANCEShall mean the intensity of light emitted from a light source per unit area in a given direction.
LUXShall mean the SI unit of illuminance. One lux is one lumen per square meter. One lux is a unit of incident illuminance approximately equal to 1/10 footcandle.
MOUNTING HEIGHTShall mean the height of the photometric center of a luminaire above grade level. The horizontal spacing of poles is often measured in units of "mounting height." Example: "The luminaires can be spaced up to four mounting heights apart."
NADIRShall mean the downward vertical vector directly beneath a luminaire.
ORNAMENTAL LIGHTINGShall mean lighting that does not impact the function and safety of an area but is purely decorative, or used to illuminate architecture and/or landscaping, and installed for aesthetic effect.
REPAIR(S)Shall mean the reconstruction or renewal of any part of an existing luminaire for the purpose of its ongoing operation, other than relamping or replacement of components including capacitor, ballast or photocell. Note that retrofitting a luminaire with new lamp and/or ballast technology is not considered a repair and for the purposes of this ordinance the luminaire shall be treated as if new. "Repair" does not include normal relamping or replacement of components including capacitor, ballast or photocell.
REPLACEMENT LIGHTINGShall mean lighting installed specifically to replace existing lighting that is sufficiently broken to be beyond repair.
SKY GLOWShall mean the brightening of the nighttime sky that results from scattering and reflection of artificial light by moisture and dust particles in the atmosphere. Skyglow is caused by light directed or reflected upwards or sideways and reduces one's ability to view the night sky.
TEMPORARY LIGHTINGShall mean lighting installed and operated for periods not to exceed 60 days, completely removed and not operated again for at least 30 days.
TOWNSHIP AGENCYShall mean the Saddle Brook Township entity having jurisdiction over outdoor lighting, including the Planning Board, Zoning Board, Zoning Officer, Township Engineer, Construction Official, Public Works, or Code Enforcement Officer, as applicable.
UPLIGHTShall mean for an exterior luminaire, light emitted at or above the horizontal plane.
