Indoor Basketball Court Lighting Guide
Lighting Design for Gymnasiums and Indoor Arenas

Indoor basketball facilities rely on ceiling-mounted lighting systems rather than pole-mounted luminaires. Because fixtures are installed directly above the court, glare control and optical distribution are critical design considerations.

Typical Indoor Basketball Court Illumination Levels

Level of PlayAverage Illumination
Professional Arena100–150 foot-candles
Collegiate Competition75–100 foot-candles
High School Gym50–75 foot-candles
Recreational Facilities30–50 foot-candles

Uniformity Targets

MetricTarget
Average-to-Minimum Ratio1.7:1
Maximum-to-Minimum Ratio3.0:1

Uniform illumination prevents bright zones beneath fixtures and darker areas near the sidelines.

Fixture Placement Strategy

Indoor fixtures are typically mounted in rows parallel to the court. Engineers design layouts to ensure overlapping light patterns produce consistent brightness across the entire playing surface.

Ceiling HeightTypical Fixture Type
20–25 ftHigh-bay LED fixtures
25–35 ftSports optic luminaires
35 ft+High-output arena lighting

Glare Control in Indoor Facilities

Because players frequently look upward toward the basket, fixtures must incorporate optical shielding and controlled beam angles to reduce direct glare.

Summary
Indoor basketball lighting systems must provide consistent illumination while minimizing glare for players shooting toward the basket. Proper fixture placement, optical design, and photometric modeling ensure clear visibility across the entire court.

Indoor basketball court lighting must provide uniform illumination and glare control for gymnasiums and arenas. This guide explains illumination levels, fixture placement, and lighting design principles for indoor basketball facilities.
