CRITICAL DESIGN ISSUES:
Direct Glare: Locate and shield or lens luminaires to avoid direct glare.
With indirect fluorescent luminaires this is not an issue.
Flicker (and Strobe): Flicker and strobe of fluorescent luminaires is
generally not an issue when using electronic ballasts. If it does occur, it can
impair the viewing of high-speed objects such as a tennis ball.
Light Distribution on Task Plane (Uniformity): The lighting system needs to
uniformly illuminate the court. Any dark spots or patterns of light will create
confusing and distracting areas.
Target Horizontal Illuminance ( 10%): For recreational class of play: 500
lux (50 fc). For other classes of play, see IESNA RP-6. Refer to UFC 4-
740-02N for additional requirements.
Traditionally tennis courts are illuminated with metal halide lamps. While this is a
common solution, indirect T5HO fluorescent uplights can provide a much better visual
environment. Additionally, the initial cost of the system is the same or less expensive
than a metal halide system and the fluorescent maintenance and energy costs are
lower. When daylight is plentiful, the fluorescent lighting can be dimmed or turned off.
