Lighting a basketball hall to FFBB standards: levels, uniformity and ball protection
FFBB classifications, illuminance levels in lux, uniformity U0 and ball protection: everything for lighting a basketball hall to the standards.
7 min readUpdated on September 9, 2026

Lighting a basketball hall to FFBB standards is not just a matter of reaching a lux level: illuminance, uniformity, visual comfort and impact resistance must be combined. This article details the requirements of the French Basketball Federation by federation classification, good design reflexes and the technical criteria for durable LED lighting. The aim: a court that is readable for the players, compliant for competition and economical in use.
Why basketball hall lighting follows precise specifications
Basketball is a fast sport, with high ball trajectories and phases of play in the air (shots, blocks, rebounds). Lighting must therefore guarantee good perception of the ball and the lines over the whole playing surface, without creating shadow areas or disturbing glare during aerial phases. Added to this are constraints specific to gymnasiums: high ceilings, the presence of stands, sometimes multi-sports use.
The FFBB governs these conditions in its Regulations for Halls and Courts. The illuminance level required depends on the federation classification of the hall, itself linked to the level of competition hosted. The higher the level, the stricter the requirements for quantity of light (horizontal illuminance in lux) and quality (uniformity, absence of glare).
FFBB illuminance levels by classification
The FFBB defines hall classifications (often written H1, H2, H3) which correspond to minimum horizontal illuminance levels measured on the playing area. As a benchmark commonly used in federation documentation:
- Classification H1 (departmental and regional championships): of the order of 300 lux for older buildings, and 500 lux for new buildings.
- Classification H2 (pre-national level and certain French championships): of the order of 500 lux.
- Classification H3 (highest national and professional levels): of the order of 750 lux.
These values are minimum average illuminance levels. For televised matches, the requirements rise sharply · often around 1,500 lux of vertical illuminance with reinforced uniformity · to satisfy the cameras. As the exact levels and measurement methods are subject to change, always check the edition of the FFBB regulations in force before finalising a project.
Good reflex: illuminance is measured at a defined number of points distributed over the playing area (FFBB documentation mentions for example a survey at several points), in order to check both the average and the actual uniformity.
Uniformity U0: a criterion as important as the lux level
Reaching the right average is not enough. Uniformity describes how even the light is over the playing surface. It is expressed as the ratio between minimum and average illuminance (Emin/Emoy), commonly written U0. The FFBB considers uniformity satisfactory when this ratio reaches at least 0.7 on the playing area.
Insufficient uniformity results in darker areas in the corners or under the baskets, which hinder refereeing and the players. Reaching a high U0 requires a regular layout of luminaires, optics suited to the height of the gymnasium and a prior photometric study rather than installation "by eye".
Controlling glare: UGR, optics and layout
In basketball, players frequently look upwards. Poorly shielded luminaires then become direct sources of glare. This risk is assessed by the UGR index (Unified Glare Rating): the lower it is, the higher the comfort. To limit glare in a gymnasium, closed or louvred optics, a good mounting height and an orientation that avoids the direct line of sight of players in the air are favoured.
We detail this notion, common to sport and commercial buildings, in our dedicated article: understanding and controlling UGR on sports grounds.
Colour temperature and CRI: readability and comfort
Colour temperature (in kelvins) influences the perception of the space. For a sports hall, a neutral white (around 4000 K) is generally chosen, which offers good liveliness without excessive coldness. The colour rendering index (CRI) must be sufficient to distinguish shirts, lines and the ball clearly; a CRI of at least 80 is a reasonable benchmark, more for televised use. These settings are a matter of visual comfort as much as compliance.
Ball protection: the IK rating, essential in basketball
A gymnasium is an environment with impacts. Balls, knocks, handling: the luminaires must withstand them. That is the role of the IK rating, which qualifies resistance to mechanical impacts. For a team sports hall such as basketball, a high IK rating is typically targeted (of the order of IK08 to IK10 depending on exposure), possibly supplemented by protective grilles. The IP rating, for its part, qualifies protection against dust and water; it is less critical indoors than outdoors, but should still be checked according to conditions.
Choosing a robust LED luminaire, with good heat dissipation and a good driver, also secures the lifetime of the installation. To go further on this point, see our guide to assessing the reliability of LED lighting.
Why switch to LED for a basketball hall
Compared with old sources (metal halide, fluorescent), LED brings instant start (useful after a power cut or for multi-purpose use), much higher luminous efficacy in lm/W, a longer lifetime and the possibility of controlling and dimming the lighting. For a facility manager, this means reduced consumption and less frequent maintenance · a decisive argument over the operating life of a gymnasium.
On the equipment side, the Rexylum offer for sports halls covers gymnasium lighting needs, with solutions suited to high ceilings. An area lighting luminaire such as the FUTURE BALL LED, 360° area lighting, illustrates the type of product designed to cover large playing surfaces effectively.
Method: from audit to photometric study
A successful project follows a simple logic: identify the classification targeted, survey the geometry of the hall (dimensions, height, presence of stands), define the target illuminance and uniformity, then simulate the layout with a photometric study. This validates the lux level, U0, UGR and compliance before any purchase, and avoids unpleasant surprises at commissioning.
Also anticipate the actual use of the hall. Many gymnasiums are multi-sports: the lighting must then suit basketball as well as handball, volleyball or badminton, whose layout and anti-glare requirements differ. Control takes on its full meaning here: dimming or creating lighting scenes makes it possible to adjust the level according to the activity (training, match, event, simple maintenance) and to make substantial savings. Lighting designed from the outset for these different modes of use will be more comfortable, more compliant and more economical over the whole operating life of the facility.
FAQ
What illuminance level is needed for a club basketball hall?
For club use at departmental or regional level (classification H1), of the order of 300 to 500 lux is used depending on the age of the building. National levels require more (H2 ≈ 500 lux, H3 ≈ 750 lux). Always check the edition of the FFBB regulations in force.
What is uniformity U0 and what value should be targeted?
Uniformity U0 is the ratio between minimum and average illuminance on the playing area. The FFBB considers uniformity satisfactory from a ratio of at least 0.7. The higher the value, the more even the light.
What IK rating should be chosen to protect luminaires from balls?
In a basketball hall, a high IK rating is favoured (typically IK08 to IK10 depending on exposure), possibly supplemented by protective grilles, to withstand ball impacts.
Is LED compatible with televised use?
Yes. LED makes it possible to reach the high vertical illuminance levels required for TV capture (often of the order of 1,500 lux) with reinforced uniformity, provided the sizing and study are appropriate.
Need a photometric study?
The audit and the photometric study are the work of a lighting design office: we recommend the expertise of the Luminance Consulting agency, the lighting design office that contributes to developing our ranges of luminaires based on an in-depth analysis of the needs of the most demanding customers. Luminance carries out the audit of your installation, the DIALux study and the compliance check. Rexylum, for its part, designs and supplies the prescribed luminaires and lighting solutions: for the choice of equipment, contact us.
