Lighting upgrade for the tennis court in Celles
For this project in Celles, the objective was not to completely replace the existing installation, but to improve the current lighting with a targeted complementary solution. STADÉLUM proposed a photometric study and the addition of 2 STADIUM 600W LED floodlights to improve the illuminance level across the playing surface.
Context
Improving existing lighting rather than replacing the entire installation
The tennis court in Celles already had a lighting installation. The client's request was to improve the existing lighting level without completely replacing the supports, wiring and overall site infrastructure.
This type of project requires a different approach from a new installation. Simply choosing a powerful floodlight is not enough: the areas requiring improvement must be identified while taking into account the existing poles, the court environment, aiming constraints and the actual impact of each additional luminaire.
Technical reference
FFT recommendations for outdoor tennis court lighting
For an outdoor tennis court, the French Tennis Federation (FFT) specifies a maintained average horizontal illuminance of 300 lux. The U0 uniformity ratio must be at least 0.70, with the average calculated using a grid of 24 measurement points.
Average illuminance
Outdoor target: maintained average illuminance of 300 lux across the playing area.
U0 uniformity
Target: Emin / Eavg ≥ 0.70 to avoid excessively dark areas.
Measurement grid
The average illuminance is calculated from 24 measurement points.
Our methodology
A lighting study to assess the actual benefits of the upgrade
Existing installation analysis
We start with the existing installation: pole positions, aiming of the existing floodlights, court geometry and surrounding constraints.
Identifying areas for improvement
The objective is to add light where it is needed without unnecessarily increasing the number of floodlights or creating lighting imbalances.
Photometric simulation
The study makes it possible to visualise the contribution of the additional floodlights, the increase in illuminance levels and the transition areas across the court.
Solution selection
The selected solution uses 2 STADIUM 600W LED floodlights, sized to provide targeted additional lighting.
Photometric study
Visualising the lighting upgrade before installation
The photometric simulation makes it possible to verify that adding the STADIUM floodlights is consistent with the requirements of the court. It serves as a decision-making tool before installation and reduces the risk of an oversized or poorly aimed solution.
Selected solution
2 STADIUM 600W LED floodlights to complement the existing court lighting
The solution proposed by STADÉLUM consists of adding 2 STADIUM 600W LED floodlights. This choice provides targeted additional lighting suited to an already equipped site where the requirement is to complement rather than completely replace the existing installation.
For this type of project, the added value lies in proper sizing: selecting the right number of floodlights, the appropriate power and the correct aiming to improve the result without unnecessarily complicating the installation.

Site photos
A lighting project integrated into an existing environment
The site photos show the court environment, existing poles and overall configuration that need to be taken into account. This on-site assessment is essential when designing a realistic solution.
What this project demonstrates
A lighting upgrade requires a proper photometric analysis
Adding floodlights to an already equipped court may seem simple. In practice, there is a risk of creating areas that are too bright, leaving poorly lit areas unchanged or increasing visual discomfort if the aiming angles and power levels are not properly studied.
The STADÉLUM approach is to treat the upgrade as a technical project: analysis of the existing installation, simulation, optics selection, appropriate power and support in implementing the selected solution.
FAQ
Frequently asked questions about upgrading outdoor tennis court lighting
Can existing lighting be upgraded without replacing the entire installation?
Yes, provided that the photometric impact of the solution is assessed. A study makes it possible to determine whether adding complementary floodlights genuinely improves the lighting level and uniformity.
Why not simply add more powerful floodlights?
Power alone does not guarantee a good result. Aiming, optics, mounting height, pole positions and luminous flux distribution are key factors in achieving uniform and comfortable lighting.
What illuminance level should be targeted for an outdoor tennis court?
The FFT reference for an outdoor court is a maintained average illuminance of 300 lux, with minimum uniformity of 0.70 across the measurement grid. To account for the ageing of the installation, a higher level may be targeted at commissioning.
