Indoor Basketball Courts
Pendant mounted direct/
indirect lights minimize
shadowing and prevent direct
with electric lighting system.
Pendant mounted linear
4' linear fluorescent T8 or T5HO
Manual on/off or integrate
lamps, 3500K color temperature, 75
(50% direct / 50% indirect)
CRITICAL DESIGN ISSUES:
Direct Glare: Locate and shield or lens equipment to avoid direct glare.
Light Distribution on Task Plane (Uniformity): The lighting system needs to
uniformly illuminate the court. Any dark spots or patterns of light will create
a confusing and distracting area.
Reflected Glare: Polished wood floors can reflect the image of the lamp
above causing an annoying distraction.
Shadows: Minimize shadows to enhance the view of the ball and other
Target Horizontal Illuminance ( 10%): For recreational class of play: 300
lux (30 fc). For other classes of play, see IESNA RP-6. Refer to UFC 4-
740-02N for additional requirements.
Traditionally basketball courts and gymnasiums are illuminated with metal halide lamps.
While this is a common solution, indirect T5HO fluorescent uplights can provide a much
better visual environment. Such a system reduces direct and reflected glare.
