How many lumens do I need to light a tennis court?
To determine the appropriate lumen requirements for lighting a tennis court, several factors must be considered, including energy efficiency, glare control, and illumination uniformity. Based on advancements in LED technology, modern systems offer superior performance compared to traditional sodium lamps. A 126W LED luminaire provides high lumen output while saving 70% energy compared to conventional 400W discharge lamps.
A typical full-sized tennis court (23.77m × 10.97m) requires horizontal illuminance levels of 300–750 lux for recreational to professional use. Assuming an average target of 500 lux and accounting for light distribution losses, the total lumen requirement can be estimated using the formula:
For a 260 m² court, this translates to approximately 195,000–390,000 lumens, depending on lighting design and fixture efficiency. LED systems, such as those with 200 lm/W efficacy, can achieve these levels with fewer fixtures and lower energy consumption.
Key recommendations:
LED Technology: Prioritize high-efficiency LEDs to reduce energy use while maintaining brightness.
Uniformity: Ensure even light distribution using diffusers and reflective optics to minimize shadows and glare.
Smart Controls: Implement adaptive dimming to adjust brightness for training (300 lux) versus competitions (750 lux), optimizing energy use.
By integrating these principles, a tennis court can achieve optimal visibility, energy savings, and compliance with lighting standards.

FAQ：
1. How many lumens are required to light a tennis court?
Recreational use: 74,000–111,000 lumens
Club/competitive play: 111,000–185,000 lumens
Professional/TV broadcasts: 185,000–370,000+ lumens
2. What is the standard size of a tennis court?
Doubles court: 78 ft × 36 ft (23.77 m × 10.97 m ≈ 260 m²).
3. Are LED lights better for tennis courts?
Yes. LEDs are more efficient (>100 lm/W), longer-lasting, and reduce glare compared to traditional HID/Metal Halide lights.
4. Do regulations affect tennis court lighting?
Yes. Check local rules for light trespass, glare limits, and energy efficiency standards.
