Table II: Guidelines For Structure Lighting
- The illumination of structures that consist of uniformly dark materials or that contain reflective-coated glass is discouraged.
- The illumination of tall, slender structures or monuments, such as flagpoles, where stray light is difficult Or impossible to control, is discouraged.
- Equip luminaires with devices to eliminate stray light as much as possible. Examples of such devices are four-sided shields, internal louvers, and top visors.
- Locate structure lighting luminaires in places where the unshielded light source cannot be seen be pedestrians or motorists.
- Average illuminance levels (vertical. measured at the structure face):
- Bright surroundings and light surfaces: 1.0 to 5.0 footcandles
- Bright surroundings and medium surfaces: 1.0 to 6.0 footcandles
- Dark surroundings and light surfaces: 0.5 to 2.0 footcandlcs
- Dark surroundings and medium surfaces: 0.5 to 3.0 footcandles
Definitions
Full Cut Off Lighting - "A light 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."
Horizontal Illuminance - "The measurement of brightness from a light source, usually measured in footcandles or lumens, which is taken through a light meter's sensor at a horizontal position." Vertical Illumination "The measurement of brightness from a light source, usually measured in foolcandles or lumens. which is taken through a light meter's sensor at a vertical position."
