Direct light.Light emitted directly from the lamp, off of the reflector or reflector diffuser, or through the refractor or diffuser lens, of a luminaire.
Essential lighting.Outdoor lighting which is designed to illuminate entrances, exits and common areas and discourage undesirable activity, by providing the minimum illumination necessary to provide security for buildings and property, and safe passage for persons utilizing parking areas, streets, sidewalks, trails and other common areas.
Fixture.The assembly that houses the lamp or lamps and can include all or some of the following parts: a housing, a mounting bracket or pole socket, a lamp holder, a ballast, a reflector or mirror, and/or a refractor or lens.
Flood or spotlight.Any light fixture or lamp that incorporates a reflector or a refractor to concentrate the light output into a directed beam in a particular direction provided it does not create a nuisance for adjacent properties.
Fully shielded lights.Outdoor light fixtures shielded or constructed so that no light rays are emitted by the installed fixture at angles above the horizontal plane as certified by a photometric test report.
Glare.Light emitting from a luminaire with an intensity great enough to reduce a viewer's ability to see, and in extreme cases causing momentary blindness.
Grandfathered luminaires.Luminaires not conforming to this Code that were in place at the time this Code was voted into effect. When an ordinance "grandfathers" a luminaire, it means that such already-existing outdoor lighting does not need to be changed unless a specified period is specified for adherence to the Code.

Lamp.The component of a luminaire that produces the actual light.
Light trespass.The shining of light produced by a luminaire beyond the boundaries of the property on which it is located.
Lumen.A unit of luminous flux. One foot-candle is one lumen per square foot. For the purposes of this article, the lumen-output values shall be the initial lumen output ratings of a lamp.
Luminaire.This is a complete lighting system, and includes a lamp or lamps and a fixture.
Non-essential lighting.Outdoor lighting for landscaping, architectural features, display areas, tennis courts, ball fields and the like.
Outdoor lighting.The nighttime illumination of an outside area or object by any man-made device located outdoors that produces light by any means.
