Subd. 5. Light Cast No light or combination of lights, which cast light on a public street, shall exceed one (1) foot-candle meter reading as measured from the centerline of the street, nor shall any light or combination of lights, which cast light on residential property, exceed four -tenths (0.4) foot-candles. 1350.05 Minimum Standards. Subd. 1. Minimum Standards for Lighting with a Total Cutoff Angle of Greater than 90 Degrees. When a luminaire has a total cutoff of an angle greater than ninety (90) degrees (see illustration below), the maximum illumination and the maximum permitted luminaire height is designated below. This standard is designed to ensure that no light is emitted above a horizontal plane parallel to the ground. In order to achieve a total cutoff at ninety (90) degrees, such a luminaire will emit maximum (peak) candle power at an angle not exceeding seventy-five (75) degrees. This angel is formed by the line at which maximum candlepower is emitted for the light source and a line perpendicular to the ground from the light source. Use and District Maximum Permitted Illumination at Maximum Permitted Height a Point Six Feet Above the Ground (in foot candles) All Residential Districts .30 Fifteen (15) feet All Non -Residential Districts 1.50 Twenty (20) feet Illustration Subd. 2. Minimum Standards for Lighting with a Total Cutoff Angle of Less than 90 Degrees. When a luminaire has a total cutoff of light at an angle less than ninety (90) degrees and is located so that the bare light bulb, lamp, or light source is completely shielded from the direct view of an observer five (5) feet above the ground at the point where the cutoff angle intersects the ground, the maximum permitted illumination and the maximum permitted height is illustrated below. This type of light fixture may be taller and provide greater illumination at the property line than the one specified above, because the design of this fixture ensures that its light source will not be directly visible off -site. Use and District Maximum Permitted Illumination at Maximum Permitted Height a Point Six Feet Above the Ground (in foot candles) All Residential Districts 1.00 Fifteen (15) feet All Non -Residential Districts 3.00 Thirty (30) feet Illustration Subd. 3. Minimum Standards for Lighting on Agricultural Lands. When a permanent outdoor luminare is placed on agricultural land, only Mercury lamps shall be permitted. Subd.4.
