`
`59 EXTERIOR LIGHTING
`
`591 Purpose The City of Greenville desires to enhance the beauty of the area for its
`citizens both during the day and at night This includes the restriction of light
`trespass light pollution and glare so that safety and security will not be
`jeopardized and night vision will be enhanced
`
`592 Definitions
`
`1 AVERAGE TO MINIMUM The ratio of average foot candles to the minimum
`footcandle point calculation or reading for a given area This ratio is an
`indicator of lighting uniformity The lower the ratio the better the uniformity
`2 CUTOFF A luminaire light distribution where the candela per 1000 lamp
`lumens does not numerically exceed 25 25 at a vertical angle of 90 degrees

`

`above nadir and 100 10
`at a vertical angle of 80 degrees above nadir This
`applies to all lateral angles around the luminaire
`3 EXTERIOR LIGHTING The nighttime illumination of an outside area or object
`by any manmade device located outdoors that produces light by any means
`
`4 FIXTURE The assembly that houses the lamp or lamps and can include all or
`some of the following parts housing mounting bracket or pole socket lamp
`holder ballast reflector or mirror andor refractor or lens
`
`incorporates a
`lamp that
`fixture or
`5 FLOOD OR SPOTLIGHT Any light
`reflector or a refractor to concentrate the light output into a directed beam in a
`particular direction with a wide or narrow beam
`
`6 FOOT CANDLES The amount of light falling on a surface measured or
`calculated It can be quantified as one lumen per square foot For an
`approximate conversion from lux to foot candles divide by ten The exact
`conversion is 1076 lux equals one foot candle
`
`7 FOOT CANDLES AVERAGE The average of a number of points of foot
`candle calculations or foot candle readings in a given area
`
`8 FOOT CANDLES INITIAL Foot candles
`that
`calculated with no
`adjustment
`for dirt buildup in the fixture or lamp lumen depreciation Initial
`foot candles should be measured when a lighting system is new and after 100
`hours of lamp burnin time
`
`are
`
`9 FOOT CANDLES MINIMUM The minimum footcandle point calculation or
`reading in a given area
`
`10 FULL CUTOFF A luminaire light distribution where zero candela intensity
`occurs at an angle of 90 degrees above nadir and at all greater angles from
`nadir Additionally the candela per 1000 lamp lumens does not numerically
`exceed 100 10
`at a vertical angle of 80 degrees above nadir This applies to
`all lateral angles around the luminaire
`11 LAMP The component of a luminaire that produces the actual light
`12 LIGHT TRESPASS The shining of light produced by a luminaire beyond the
`boundaries of the property on which it is generally located and intended
`13 LUMINAIRE This is a complete lighting system and includes a lamp or lamps
`and a fixture housing reflectors refractor etc
`14 LUMINANCE What we commonly call brightness or the light coming from a
`surface Luminance is composed of the intensity of light striking an object or
`surface and the amount of that light reflected back toward the eye All surfaces
`have some reflecting qualities and therefore have luminance light surfaces
`being more reflective than dark surfaces The luminance of asphalt pavement
`and the moon can both be measured
`
`15 MOUNTING HEIGHT OF LUMINAIRE The mounting height of a luminaire
`shall be the vertical distance from the ground directly below the centerline of the
`luminaire to the center of the light source lamp in the luminaire

`
`18 TEMPORARY EXTERIOR LIGHTING The nighttime illumination of an
`outside area or object by any manmade device located outdoors that produces
`light by any means for a limited period of time This period can be specified by
`the Town
`
`19 UNIFORMITY A description of the smoothness of the lighting pattern or the
`degree of intensity of light and dark areas in the roadway or area to be lighted
`Uniformity is usually expressed as a ratio such as max to min or average to min
`The lower the ratio the more uniform the lighting design
