CRITICAL DESIGN ISSUES:
Direct Glare: In a game where the ball is traveling at high speeds and all
possible angles, minimize glare to provide adequate visibility. IESNA RP-
6-01 outlines critical glare zones where poles should not be located. This
way, when a player follows the ball, they will not look directly into a
floodlight.
Light Distribution on Task Plane (Uniformity): Floodlight locations and
distribution provide uniform illuminance on the field. The uniformity and
elimination of dark spots improves visibility and minimizes distractions.
Target Horizontal Illuminance ( 10%): For various classes of play and
illuminance recommendations see Lighting Handbook, Figure 20-2 and
IESNA RP-6.
