LED lighting renovation for indoor tennis courts in Cestas
In Cestas, Gironde, STADÉLUM supported the renovation of several indoor tennis courts. The project involved replacing old sodium floodlights with SMASH 300W 4000K LED floodlights, while retaining the existing mounting positions to avoid modifying the wiring.
Context
Replacing sodium floodlights without changing the existing layout
The specifications were clear: modernise the tennis court lighting while retaining the existing mounting positions. This constraint made it possible to limit work on site and avoid modifying the wiring.
In this type of renovation, choosing the floodlight alone is not enough. It is necessary to check whether the existing mounting points allow for consistent light distribution, whether the optics are suited to the court geometry and whether the settings can limit lighting imbalances.
Before / after
From sodium to 4000K LED lighting for improved perceived light quality
The before / after photos show the change in lighting appearance: the old sodium lighting produced a strong orange tint, while the 4000K LED solution provides a more neutral light that improves visual clarity during play.
STADÉLUM method
A renovation designed around the actual constraints of the site
The renovation did not start from a blank slate. STADÉLUM worked with the existing mounting points, then adapted the choice of floodlights, aiming and power levels according to the different areas.
Existing installation analysis
The existing sodium floodlight positions were retained as the basis of the project in order to comply with the requirement not to modify the wiring.
Photometric study
The study made it possible to visualise the potential light distribution using the existing mounting points.
Power adjustment
Some floodlights were set to different power levels, particularly around the net, to balance the light output.
Adaptation to each building
The two buildings were treated with different configurations depending on height, number of courts and site geometry.
Building 1
One court with 10 floodlights mounted at approximately 7 metres
The first building contains a single tennis court. The solution was designed around 10 SMASH 300W LED floodlights installed at a height of approximately 7 metres using the existing mounting positions.
To improve lighting balance, 8 floodlights operate at 300W and 2 floodlights positioned around the net are set to 150W. This setting adapts the light output in the central area without unnecessary over-lighting.
Single-court study
Checking the consistency of the existing layout
The single-court simulation makes it possible to visualise the light distribution obtained from the existing mounting points, with specific adjustments to the floodlights positioned in the central area.
Building 2
Two courts with 12 floodlights per court
The second building contains 2 tennis courts, with a greater height ranging from 8 to 10 metres depending on the area. The solution uses 12 SMASH 300W floodlights per court.
The floodlights were set to different power levels to adapt the luminous flux to their position. In particular, the floodlights positioned around the net are set to 225W to balance the illuminance in the centre of the court.
Two-court building study
Adapting the lighting to a greater mounting height
For the two-court building, the photometric study made it possible to analyse the effect of the greater height and assess the benefits of different power settings according to each area.
What this project demonstrates
A successful LED renovation depends as much on the study as on the product
This project demonstrates the value of a technical approach: start from the actual site, assess the constraints, adapt the power levels and avoid promising results without carrying out a study.
Adaptation to the existing installation
The solution was designed around the existing mounting positions rather than starting from a theoretically ideal layout.
Adjusted power levels
The 150W or 225W settings around the net help limit excess light in the central areas.
Visual comfort considered
Replacing sodium lighting with 4000K LED lighting changes the orange-tinted light to a more neutral and clearer appearance.
Product used
SMASH: the LED floodlight selected for this tennis lighting renovation
For this project in Cestas, the SMASH 300W 4000K LED floodlight was used to replace the old sodium floodlights while retaining the existing mounting positions. The choice of luminaire was part of a complete approach: photometric study, adjustment of power levels according to the different areas and verification of the consistency of the layout.

FAQ
LED lighting renovation for indoor tennis courts
Why can retaining the existing mounting positions be a constraint?
Existing mounting positions do not always correspond to the optimal layout for modern LED lighting. The photometric study is therefore used to assess what can be achieved without modifying the wiring.
Why choose a 4000K colour temperature for an indoor tennis court?
4000K provides a neutral white appearance that is generally more comfortable and natural than the orange tint of older sodium sources. The final choice should nevertheless remain consistent with visual comfort, intended use and the site's requirements.
Why set some floodlights to 150W or 225W?
Not all floodlights contribute to the court lighting in the same way. Different power settings make it possible to balance the different areas, particularly around the net, where the risk of over-lighting can be greater.
Tennis renovation project?
Indoor tennis lighting should be studied before it is replaced
Available height, existing mounting positions, wiring, optics, required illuminance level, uniformity and visual comfort: STADÉLUM helps you transform an existing installation into an LED solution suited to your site.
