How many lights do you need for a tennis court
Designing an effective lighting system for a tennis court involves balancing illuminance uniformity, glare control, energy efficiency, and compliance with sports lighting standards. The number of required fixtures depends on the lighting technology, court dimensions, and application requirements (recreational vs. professional).
1. Key Factors Influencing Fixture Quantity
Illuminance Standards
The Illuminating Engineering Society (IES) RP-6-15 guidelines recommend horizontal illuminance levels of 300–750 lux for tennis courts, depending on usage (recreational to professional). Uniformity ratios should exceed 0.7 to ensure consistent visibility across the court. Achieving these metrics requires precise fixture placement and output calibration.
Glare Control
Glare disrupts player performance and spectator comfort. Unified glare rating (UGR) models effectively predict discomfort, with LED luminance and background contrast being critical factors. Modern LED systems use volume scattering diffusers (≥70% transmittance) and reflective cavities (≥85% reflectivity) to distribute light evenly while minimizing glare.
LED Lights
LED Systems: High-efficiency LEDs produce 200+ lumens per watt, enabling fewer fixtures.
2. Calculating Fixture Requirements
For a standard tennis court (23.77m × 10.97m, ~260m²):
Total Lumen Requirement
Fixture Quantity:
High-output fixtures (e.g., 30,000 lumens each) require 6–8 units to meet professional standards.
3. Layout and Configuration
Symmetrical Arrangement: Fixtures are typically mounted on poles along the court’s sides, angled to avoid direct glare.
Height and Spacing: Elevated mounting (20–30 feet) ensures wide coverage. For LED systems, spacing between poles ranges from 8–12 meters.
Smart Controls: Adaptive dimming adjusts brightness between training (300 lux) and competitions (750 lux), optimizing energy use without additional fixtures.
A standard tennis court typically requires 6–8 high-efficiency LED fixtures to meet professional lighting standards, though exact numbers depend on luminaire specifications and design goals. Prioritizing LED technology with glare-reducing optics and smart controls ensures compliance with IES guidelines while enhancing energy efficiency and player performance.
