As used in this zoning code, unless the context clearly indicates otherwise, certain words and phrases shall mean the following.
   ABANDONMENT. The discontinuation of use for a period of 12 months.
   ACREAGE, NET. The remaining ground area in acres after deleting all portions for proposed and existing public streets and roadways within a development project or subdivision.
   AIRPORT NAVIGATION LIGHTING SYSTEMS. The airport tower beacon, runway lights, guidance lights for landings, taxiway lighting and any other lighting on airport property required by the state or the Federal Aviation Administration.
   CLASS 1 LIGHTING. All outdoor lighting used for, but not limited to, outdoor sales or eating areas, principal public entryways, assembly or repair areas, advertising and other signs, recreational facilities and other similar applications where color rendition is important to preserve the effectiveness of the activity.
   CLASS 2 LIGHTING. All outdoor lighting used for, but not limited to, illumination for walkways, roadways, equipment yards, parking lots, emergency exits and outdoor security where general illumination of the grounds is the primary concern.
   CLASS 3 LIGHTING. Any outdoor lighting used for decorative effects, including, but not limited to, architectural illumination, flag and monument lighting, and illumination of trees, bushes, landscape features and the like.
   CORRELATED COLOR TEMPERATURE (CCT). A measure, expressed in Kelvins (abbreviated as K) of the apparent hue of white light sources such as metal halide, fluorescent and white LED. Higher CCT sources appear bluer or cooler; lower CCT sources appear yellower or warmer.
   DEVELOPMENT PROJECT. Any residential, commercial, industrial or mixed use subdivision plan or development plan which is submitted to the town for approval.
   DIRECT  ILLUMINATION. Illumination resulting from light emitted directly from a lamp or luminaire, not light diffused through translucent signs or reflected from other surfaces such as the ground or building faces.
      (1)   A light fixture or luminous tube constructed and mounted such that all light emitted by the fixture or tube, either directly from the lamp, tube, or a diffusing element, or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal.
      (2)   A practical working way to determine if a fixture or tube is fully shielded: if the lamp or tube, any reflective surface, or lens cover (clear or prismatic) is visible when viewed from above or directly from the side, from any angle around the fixture or tube, the fixture or tube is not fully shielded.
      (3)   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.
   HIGH-PRESSURE SODIUM (HPS). A type of lamp using sodium and mercury vapor at high pressure to produce a yellow or golden-hued light.
   INSTALLED. Attached, or fixed in place, whether or not connected to a power source.
   LED. A light emitting diode.
   LIGHT POLLUTION. Any adverse effect of human-made lighting, light where it is not needed or wanted or wasted light.
   LOW-PRESSURE SODIUM (LPS). A type of lamp using sodium vapor at low pressure to  produce  a yellow or amber hued light.
   LUMEN. The unit used to measure the actual amount of visible light that is produced by a lamp.
   LUMINAIRE. The complete lighting assembly, including the lamp, housing, shields, lenses and associated electronics, less the support hardware or brackets; a light fixture.
   LUMINOUS TUBE. A glass tube filled with a gas or gas mixture (including neon, argon, mercury or other gasses), usually of small diameter (ten to 15 millimeter), caused to emit light by the passage of an electric current, and commonly bent into various forms for use as decoration or signs; a “neon” tube. A LUMINOUS TUBE does not include common fluorescent tubes.
   METAL HALIDE (MH). A type of lamp using mercury and metal halide(s) to produce light.
   NARROW-SPECTRUM AMBER LED. An LED light source that emits only yellow light at and near a wavelength of 590 nanometers (nm); the intensity at 580 and 600 nm must be no higher than 50% of  the peak intensity.
   OUTDOOR LIGHT FIXTURE. An outdoor electrically-powered illuminating device, lamp, luminous tube or and similar devices, either permanently installed or portable, which is used for illumination or advertisement. Such devices shall include, but are not limited to, searchlights, spotlights and floodlights for:
      (1)   Buildings and structures;
      (2)   Recreational areas;
      (3)   Parking lot lighting;
      (4)   Landscape and architectural lighting;
      (5)   Billboards and other signs (advertising or other);
      (6)   Street lighting;
      (7)   Product display area lighting;
      (8)   Building overhangs and open canopies;
      (9)   Pedestrian walkways or areas; and
      (10)   Building or landscape decoration.
   OUTDOOR RECREATION FACILITY. An area designed for active recreation, whether publicly or privately owned, including, but not limited to, baseball diamonds, soccer and football fields, golf courses, tennis courts and swimming pools.
   PERSON. Any individual, lessee, owner or any commercial entity including, but not limited to, firm, business, partnership, joint venture or corporation.
   TEMPORARY LIGHTING. Lighting which does not conform to the provisions of this zoning code and which will not be used for more than one 30-day period within a calendar year. TEMPORARY LIGHTING is intended for uses which, by their nature, are of limited duration (e.g., civic events or construction projects).
   TOTAL OUTDOOR LIGHT OUTPUT. The maximum total amount of light, measured in lumens, from all outdoor lighting installed on a development project. Includes all lights and luminous tubing used for Class 1, Class 2, Class 3 lighting and lights used for external illumination of signs, but does not include lights used to illuminate internally illuminated signs or luminous tubing used in neon signs. For lamp types that vary in their output as they age (such as metalhalide), the initial output, as defined by the manufacturer, is the value to be considered. For determining compliance with § 17.5(C) of this zoning code, the light emitted from outdoor light fixtures is to be included in the total output as follows.
      (1)   Outdoor light fixtures installed in the open such as on poles or on the sides of buildings or other structures, when not shielded from above by the structure itself, as defined in divisions (2) and (3) of this definition, are to be included in the total outdoor light output by simply adding the lumen outputs of the lamps used.
      (2)   Outdoor light fixtures installed under canopies, building overhangs or roof eaves where the center of the lamp or luminaire is located at least five feet, but less than ten feet, from the nearest edge of the canopy or overhang are to be included in the total outdoor light output as though they produced only one-quarter of the lamp’s rated lumen output.
      (3)   Outdoor light fixtures under the canopy and ten or more feet from the nearest edge of a canopy, building overhang or eave are to be included in the total outdoor light output as though they produced only one-tenth of the lamp’s rated lumen output.
