CRITICAL DESIGN ISSUES:
Color Appearance and Color Contrast: White light sources, such as metal
halide, fluorescent, and induction provide better color rendering than
frequently used high-pressure sodium sources.
Direct Glare: Because the surroundings may be very dark at night,
consider direct glare from luminaires and excessive contrast of surfaces.
Luminaires should use shielded, low wattage lamps.
Light Pollution / Trespass: The use of fully shielded or full-cutoff
luminaires eliminates direct light above the horizontal plane. While all
lighting contributes to light pollution, direct light has the largest
contribution. Using shielded or cut-off optics and low wattage lamps can
minimize light pollution. Shielded luminaires minimize the chance of light
trespass on a neighboring property or building.
