What is the ideal light uniformity for a competition indoor padel court?

A competition indoor padel court requires a minimum light uniformity of U1 = 0.7 on the playing surface. This means the difference between the darkest and the brightest spot on the court must be limited: the minimum illuminance may not be less than 70% of the average illuminance. The higher the uniformity, the fairer and safer the game.

This requirement applies to officially certified matches and is laid down in international standards for sports hall lighting. Less strict requirements apply to recreational use, but even then good light uniformity determines the playing experience and the safety of players.

In this article we answer the most frequently asked questions about lux, light uniformity and LED lighting for an indoor padel court.

Which light uniformity requirements apply to competition padel?

For competition padel, a minimum light uniformity of U1 = 0.7 applies. This is the ratio between the lowest and the average illuminance on the playing surface. With an average of 500 lux, the darkest measurement may therefore not come out lower than 350 lux. In addition to U1, U2 is also measured: the ratio between the lowest and the highest illuminance, for which a minimum of 0.5 generally applies.

These values are based on the European standard EN 12193, which was developed specifically for sports lighting installations. International padel federations such as the FIP (Federación Internacional de Pádel) align with it in their technical regulations.

In practical terms, this means the luminaires may not be placed above the court at random. The positioning, the number of luminaires, the beam distribution and the mounting height together determine whether the uniformity requirement is met. A lighting plan based on simulation software is not a luxury for competition courts, but a requirement.

What is the difference between lux and light uniformity?

Lux is a measure of the amount of light falling on a surface, expressed in lumens per square metre. Light uniformity is a ratio that indicates how consistently that light is distributed across the entire playing surface. Both values are needed to assess the quality of sports hall lighting: enough lux without good uniformity still leads to dark corners and visibility problems.

A simple example makes the difference clear. Suppose the average illuminance on a padel court is 600 lux, but in the corners the measurement drops to 200 lux. The average value sounds good, but the uniformity (200 divided by 600) is only 0.33. That falls well short of the competition standard of U1 = 0.7.

For players, low uniformity means that as they move around the court they constantly pass from brightly lit zones into darker areas. This disturbs depth perception, slows reaction time and increases the risk of injury. Lux and uniformity are therefore two inseparably linked quality indicators.

How many lux does an indoor padel court need?

An indoor padel court for recreational use needs at least 300 lux on the playing surface. For competition at national level a minimum of 500 lux applies, and for international matches or television broadcasts this can rise to 750 lux or more. The exact requirement depends on the competition level and the requirements of the organising federation.

In addition to the horizontal illuminance level on the floor, vertical illuminance also plays a role. At higher competition levels, the amount of light falling on the vertical surfaces, such as the back walls and side walls, is also measured. This is relevant for the visibility of the ball against the background and for camera systems during live broadcasts.

When designing the lighting installation, it is wise not to design exactly to the minimum values. Over the years, luminaires lose light output through wear of the light source and contamination of the reflector. A lighting plan that delivers 550 lux when put into use can drop below the competition standard after five years without maintenance.

How is light uniformity measured on a padel court?

Light uniformity on a padel court is measured using a grid of measuring points on the playing surface. At fixed, evenly distributed positions across the entire court, the illuminance is measured with a lux meter. From these measurements the average, minimum and maximum values are calculated, after which the uniformity ratios U1 and U2 are determined.

The EN 12193 standard prescribes how this measuring grid must be set up. For a padel court of 20 by 10 metres, several dozen measuring points are generally used, distributed over a regular grid. The measurement is taken at a height of 1 metre above the playing surface, which corresponds to the average playing height of the ball.

For official matches and inspections by bodies such as Kiwa ISA Sport, an independent measurement is mandatory. A lighting plan or simulation report from the supplier is not a substitute for an actual measurement on site. Environmental factors such as the reflection of walls, ceiling and floor influence the end result and are not always accurately accounted for in simulations.

Which LED lighting meets competition standards for padel?

LED lighting for a competition padel court must meet the illuminance standards of EN 12193, a colour rendering index (CRI) of at least 80 and a colour temperature between 4,000 and 6,500 Kelvin. Luminaires must be suitable for sports lighting, which means they have a directed beam that lights the playing surface evenly without causing disturbing glare for players.

For padel specifically, luminaires with an asymmetric or controlled light beam are the most suitable. Because the court is enclosed by glass and steel structure, light is easily reflected back. Luminaires with poor beam control cause reflections on the glass that hinder players when following the ball.

In addition, the ability to dim and the use of an emergency lighting circuit at larger locations are important for the permit and for operations. Modern LED lighting has a lifespan of 50,000 hours or more, which with intensive use amounts to ten to fifteen years without replacing the light source.

What are the consequences of poor light uniformity on a padel court?

Poor light uniformity on a padel court leads to reduced visibility of the ball, a higher chance of injury and unfair playing conditions. Players who move from a well-lit part of the court into a darker zone experience temporarily impaired depth vision, which directly affects reaction speed and coordination.

Besides the direct consequences for players, there are also practical consequences for the operator. A court that does not meet the uniformity requirement of U1 = 0.7 will not be approved for official matches during an inspection by Kiwa ISA Sport. This means the location may not organise competition matches until the lighting has been adjusted.

In the long term, poor lighting can also lead to negative user experiences and lower court occupancy. Players deliberately choose well-lit locations, especially when they also play recreationally at a high level. The investment in quality LED lighting with a well-considered lighting plan pays for itself through higher occupancy rates and a better reputation for the location.

Can existing padel court lighting be improved?

In most cases, existing lighting installations on a padel court can be improved or replaced without having to modify the entire court. Outdated luminaires are replaced by modern LED lighting with better beam control, and the positioning can be adjusted on the basis of a new lighting plan. In some cases extra luminaires are needed to improve the uniformity.

The first step in a lighting renovation is a measurement of the current situation. On the basis of the measured values, it is determined where the shortcomings lie: too few lux, poor uniformity or both. A new lighting plan then simulates which adjustments are needed to meet the competition standards.

A practical point of attention with existing courts is the mounting structure. Not every steel structure has suspension points in the ideal position for competition lighting. In that case an extra lighting frame can be fitted, or the luminaires can be placed on the existing structure with adapted brackets. This requires custom work per location, but is almost always feasible without taking the court out of use.
