ILLUMINATING ENGINEERING SOCIETY OF NORTH AMERICA (OR IESNA): The professional society of lighting engineers, including those from manufacturing companies and others professionally involved in lighting.

LED: A semiconductor diode that emits light when a voltage is applied to it and that is used especially in electronic devices (as for an indicator light). Warm white or filtered LEDs meet CCT <3,000 K; S/P ratio <1.2.

LZ-1: Lighting Zone 1 (the Downtown Overlay District Lighting Zone) as described in section 9-12-11 of this chapter.

LZ-2: Lighting Zone 2 (the Commercial Area Lighting Zone) as described in section 9-12-11 of this chapter.

LIGHT POLLUTION: Any artificial light that is emitted either directly or indirectly by reflection that alters the appearance of the night sky; interferes with astronomical observation; or interferes with the natural functioning of nocturnal native wildlife.

LIGHT TRESPASS: Any form of shining light emanating from a fixture that penetrates property other than that for which it is intended and permitted.

LIGHTING ZONE: A geographic area of the town as described in section 9-12-10 of this chapter. The lighting zones of the town are depicted on the map maintained in the Office of the Director. Such map is incorporated herein by reference and made a part of this chapter.

LUMENS: A unit of measurement for the actual amount of visible light which is produced by a lamp as specified by the manufacturer. A foot-candle is one lumen per square foot.

MOTION SENSOR: A mechanism for controlling illumination by turning lights on when activated by motion and remaining on during activity for a maximum of thirty (30) minutes following the last detection of motion.

OPAQUE: An outdoor light fixture in which the walls of a fixture which house the light source are comprised of a solid material, unable to be permeated by light, should a light source be held behind it. Glass is not considered opaque however, glass on a fixture may be acceptable if the glass is below the opaque aspect of the fixture which houses the light source.

OUTLINE LIGHTING ON A BUILDING OR STRUCTURE: Any arrangement or display of incandescent bulbs or lighting tubes used to outline or call attention to the features of a building, including the building's frame, shape, roofline or window dimensions. Outline lighting includes both temporary and permanent arrangement of bulbs or lighting tubing, whether located inside or outside of a building, if such bulbs or tubing is visible to the public from a public right-of-way or from an outdoor public area.

PUBLIC ART: Artwork created and placed on a site in connection with the town's public art program.

RETROFIT FIXTURE: A legal non-conforming fixture as described in Section 9-12-6B that has a permanent opaque lining applied to it which extends to the lowest portion of the bulb, or other permanent modification to the fixture approved by the Director that brings such fixture into compliance with the requirements of this Section.

SECURITY LIGHTING: A light used either commercially or residentially for protection of goods or property.

SEMIOPAQUE: An outdoor light fixture with walls of a fixture comprised of a nonopaque material such as frosted, colored glass, or material such as mica which allows for some light trespass to be emitted from the walls of the fixture, referred to as a "glow", but such that the light source is not visible through the walls. Clear glass is not considered to be semiopaque.

UNSHIELDED FIXTURE: A light fixture shielded in such a manner that the light emitted directly from the lamp or indirectly from the fixture is projected at angles above the horizontal plane without limitation.

UPLIGHTING: Lighting that is directed in such a manner as to shine light rays above the horizontal plane. (Ord. 21, Series 2007; amd. Ord. 35, Series 2007; Ord. 30, Series 2010; Ord. 1, Series 2019; Ord. 19, Series 2020; Ord. 29, Series 2020; Ord. 6, Series 2022)
