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 surfaces.

A lighting fixture constructed in such a manner that all light emitted by the fixture, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal as determined by a photometric test or certified by the manufacturer. Any structural part of the light fixture providing this shielding must be permanently affixed.
The sensation produced by a bright source within the visual field that is sufficiently brighter than the level to which the eyes have adapted to cause annoyance, discomfort, or loss in visual performance and visibility. The magnitude of glare depends on such factors as the size, position, brightness of the source, and on the brightness level to which the eyes have become adapted.
The attachment, or assembly fixed in place, whether or not connected to a power source, of any outdoor light fixture.
Any adverse effect of man-made light.
Light from an outdoor luminaire falling on an adjacent property as observed at four feet above ground at the property line.

[Added 3-13-2019 by Ord. No. 1]
An outdoor illuminating device, outdoor lighting or reflective surface, lamp or similar device, permanently installed or portable, used for illumination or advertisement. Such devices shall include, but are not limited to lights used for:

Landscape lighting;
Billboards and other signs (advertising or other);
Product display area lighting;
Illuminating building overhangs and open canopies.

Lighting which does not conform to the provisions of this chapter and which will not be used for more than one consecutive thirty-day period within a calendar year, with one consecutive thirty-day extension. Temporary lighting is intended for uses which by their nature are of a limited duration; for example holiday lighting decorations, civic events, or construction projects.

The relinquishment of a property, or the cessation of a use or activity by the owner or tenant for a continuous period of 12 months, excluding temporary or short term interruptions for the purpose of remodeling, maintaining or rearranging a facility. A use shall be deemed abandoned when such use is suspended as evidenced by the cessation of activities or conditions which constitute the principal use of the property.
It is the intent of this chapter to define practical and effective measures by which the obtrusive aspects of excessive and/or careless outdoor light usage can be minimized, while preserving safety, security and the nighttime use and enjoyment of property. These measures will reasonably curtail the degradation of the nighttime visual environment by encouraging lighting practices that direct appropriate amounts of light where and when it is needed, increasing the use of energy-efficient sources, and decreasing the wastage of light, sky glow, and glare resulting from over-lighting and poorly shielded or inappropriately directed lighting fixtures.
In adopting this chapter, credit is hereby given to the International Darksky Association for its assistance in providing valuable information and guidance.
All outdoor illuminating devices shall be installed and maintained in conformance with the provisions of this chapter, the Town of Koshkonong Building Code, the Electrical Code, and the Sign Code of the jurisdictions as applicable and under appropriate permit and inspection.
New uses, buildings and major additions or modifications. For all proposed new land uses, developments, buildings, and structures that require a building permit or other authorization from the Town, all outdoor lighting fixtures shall meet the requirements of this chapter. All building additions or modifications of 25% or more in terms of additional dwelling units, gross floor area, or parking spaces, either with a single addition or with cumulative additions subsequent to the effective date of this provision, shall be subject to the requirements of this chapter for the entire property, including previously installed and any new outdoor lighting.
