(D) DEFINITIONS: Unless specifically defined below, words or phrases used in this Article shall be interpreted so as to give them the meaning they have in common usage and to give this Section its most reasonable application.
AREA LIGHT: A luminaire equipped with a lamp that produces over one thousand eight hundred (1,800) lumens. Area lights include, but are not limited to, streetlights, parking lot lights and yard lights. (See Table 1in section 8-9-3 for light output of various lamps).
AVERAGE HORIZONTAL FOOTCANDLE: The average level of illuminance for a given situation (with snow cover if that is to be expected in the given situation) measured at ground level with the light meter placed parallel to the ground.
BUILDING OFFICIAL: The City of Menan Building Official.
EIGHTY-FIVE (85) DEGREE CUT-OFF TYPE OF LUMINAIRES: Luminaires that do not allow light to escape above an eighty-five (85) degree angle measured from a vertical line from the center of the lamp extended to the ground (see Figure 2)
EXTERIOR LIGHTING: Temporary or permanent lighting that is installed, located or used in such a manner to cause light rays to shine outdoors. Luminaires that are indoors that are intended to light something outside are considered exterior lighting for the purpose of this Article.
FLOOD LIGHT A lamp that produces up to one thousand eight hundred (1,800) lumens and is designed to flood a well-defined area with light. (See Table 1in section 8-9-3 for light output of various lamps)
FOOTCANDLE (fc). The American unit used to measure the total amount of light cast on a surface (illuminance). One footcandle is equivalent to the illuminance produced by a source of one candle at a distance of one foot. For example, the full moon produces .01 s. s are measured with a light meter. One footcandle is approximately equal to ten (10) lux, the British unit used to measure illuminance.
FULL CUT-OFF LUMINAIRES. A luminaire designed and installed where no light is emitted at or above a horizontal plane running through the lowest point on the luminaire. (See Figure 1) Fully shielded. The luminaire incorporates a solid barrier (the shield), which permits no light to escape through the barrier. (See Figure 4)
GLARE: Stray, unshielded light striking the eye that may result in (a) nuisance or annoyance glare such as light shining into a window; (b) discomfort glare such as bright light causing squinting of the eyes; (c) disabling glare such as bright light reducing the ability of the eyes to see into shadows or (d) reduction of visual performance.
HOLIDAY LIGHTING: Strings of individual lamps, where the lamps are at least three inches apart and the output per lamp is not greater than fifteen (15) lumens. Illuminance. The amount of light falling on any point of a surface measured in footcandles or lux.
IESNA: Illuminating Engineering Society of North America (IES or IESNA). The professional society of lighting engineers.
IESNA RECOMMENDED PRACTICES. The current publications of the IESNA setting forth illuminance levels.
LAMP: The generic term for an artificial light source, to be distinguished from the whole assembly (see Luminaire). Commonly referred to as "bulb".
LIGHT: The form of radiant energy acting on the retina of the eye to make sight possible.
LIGHT POLLUTION Any adverse effect of manmade light including, but not limited to, discomfort to the eye or diminished vision due to glare, light trespass, uplighting, the uncomfortable distraction to the eye, or any manmade light that diminishes the ability to view the night sky.
LIGHT TRESPASS: Light falling on the property of another or the public right-of-way when it is not required to do so.
LIGHTING Any or all parts of a luminaire that function to produce light.
LIGHTING ADMINISTRATOR: A City official designated by the City Council to administer, interpret, and enforce the Menan Outdoor Lighting Ordinance, and make recommendations thereunder.
LUMEN: The unit used to quantify the amount of light energy produced by a lamp at the lamp. Lumen output of most lamps is listed on the packaging. For example, a 60-watt incandescent lamp produces 950 lumens while a 55-watt low- pressure sodium lamp produces 8000 lumens.
LUMINAIRE: A complete lighting unit, consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps and to connect the lamps to the power. When used, includes ballasts and photocells. Commonly referred to as "fixture".
MAINTAINED ILLUMINANCE: The condition that occurs after 200 hours of lamp use prior to a point where luminaire cleaning is necessary. Measurements are taken at ground level with sensor parallel to the ground for horizontal illuminance and measured at 5 feet above ground with sensor perpendicular to the ground for vertical illuminance.
NON-ESSENTIAL LIGHTING: Lighting that is not necessary for an intended purpose after the purpose has been served. Does not include any lighting used for safety and/or public circulation purposes.
PARTIALLY SHIELDED: The luminaire incorporates a translucent barrier, the "partial shield" around the lamp that allows some light to pass through the barrier while concealing the lamp from the viewer. (See Figure 3)
PLANNING AND ZONING ADMINISTRATOR: The City of Menan Planning and Zoning Administrator/Commission.
SKYGLOW: The overhead glow from light emitted sideways and upwards. Skyglow is caused by the reflection and scattering of light by dust, water vapor and other particles suspended in the atmosphere. Skyglow reduces one's ability to view the night sky.
TEMPORARY LIGHTING: Lighting that is intended to be used for a special event for seven days or less.
UPLIGHTING: Fully shielded lighting that is directed in such a manner as to shine light rays above the horizontal plane.
