Examples of Artificial light in a sentence

• Artificial light properly distributed and of an intensity of not less than thirty (30) foot candles shall be provided.

• Artificial light may only be used to hunt Fox, Raccoon, Coyote, and Opossum.

• Artificial light sources shall be provided equivalent to at least 20 foot candles three (3) feet off the floor, except that 100 foot candles shall be provided at the level where cosmetology is being performed, and where equipment is assembled.

• Artificial light used in conjunction with the lighting of any sign shall not be directed or reflected onto any structure or constitute a hazard to the safe and efficient operation of vehicles upon a street or highway.

More Definitions of Artificial light

Artificial light means a flashlight, lantern of any kind, torch, flare, spotlight or the headlights of any vehicle and any other source of illumination other than the sun and the moon and the stars;

Artificial light means the light emanating from any human-made device.2 1 There are two forms of artificial light that have the most significant impact on sea turtle nesting habitats. The first is “light trespass” (often called “obtrusive light”), which refers to light spilling out of the area it is intended to illuminate. The second is “glare,” which refers to unwanted source luminance or brightness from an observer’s perspective. Glare occurs when visual field brightness is greater than the luminance to which the eyes are adapted, regardless of whether this light actually illuminates the area in which the observer is located. Glare causes the eye to continually be drawn toward the bright source and may also prevent the observer from adequately viewing an intended target. For example, an outdoor artificial light on a building façade may not measurably illuminate the beach but may still be visible to sea turtle hatchlings. See Philip M. Garvey, Environmental Impact of On-Premise Identification Sign Lighting With Respect to Potential Light Trespass, Sky Glow, Glare, United States Sign Council Foundation, ii (2004); Douglas Mace, et al., Countermeasures for Reducing the Effects of Headlight Glare, AAA Foundation for Traffic Safety, 13 (2001). An effective lighting ordinance will ideally address both forms of artificial light in order to provide meaningful protection to sea turtle nesting habitats. Because glare, more so than light trespass, presents greater challenges for municipal or county enforcement officers (discussed in detail below), this model ordinance provides two alternative lighting standards to be applied within the Sea Turtle Friendly Lighting District. One standard addresses light trespass alone, while the second (demarcated with an asterisk) incorporates both light trespass and glare. [See footnote 2 for a note on the third major form of artificial light.]
