Sports field lighting standards define the illuminance, uniformity, glare control and visual conditions a sports facility should achieve. The applicable requirements depend on the sport, competition level, venue type and whether television broadcasting is involved.
EN 12193 is the most widely referenced standard for sports lighting projects. It groups sports facilities into three lighting classes, but it does not assign one universal lux level to every sport — Class I football requires 500 lux, while Class I horse racing requires only 200 lux. A football field, tennis court and swimming facility can have different requirements even when they are classified at the same competition level.
This guide explains the main sports lighting metrics and compares sport-specific requirements side by side, helping project teams determine which standard and lighting class should be confirmed before the lighting design begins.

Understanding Lighting Classes: EN 12193 vs IES RP-6
EN 12193 divides sports lighting into three classes according to level of play, spectator distance and visual demand:
| Lighting Class | Typical Application |
|---|---|
| Class I | High-level, national or international competition with larger spectator capacity |
| Class II | Regional competition, club competition and higher-level training |
| Class III | Recreational use, school activities, local training and general sports use |
These classes provide a framework, not fixed lux values that apply to every sport. Class I football and Class I golf practice areas do not share the same illuminance requirement — the sport-specific table must always be checked.
Regional note: North America’s IES RP-6 also uses “Class” terminology, but defines four classes (Class I through Class IV) — not three — with different numeric thresholds tied to level of play, spectator size and broadcast requirements. EN 12193 and IES RP-6 are not interchangeable, and neither is a fixed lux value that applies globally: national standards, tender specifications or governing-body requirements may apply instead. Always confirm which standard — and which class system — the project’s jurisdiction and specifying document actually reference before using class-based figures.
Beyond EN 12193: Where CIE Standards Come In
EN 12193 and IES RP-6 define illuminance, uniformity and glare — but they are not the only reference documents that appear in real tender specifications, especially for larger or televised projects:
- CIE TR 83 — addresses lighting for television and broadcast coverage of sports events, including vertical illuminance requirements toward camera positions. Broadcast-grade stadium tenders often reference this alongside, not instead of, EN 12193’s Class I baseline.
- CIE 112 / CIE 150 — address glare evaluation and obtrusive light (light spill/light pollution), relevant when a facility sits near residential areas or is subject to local lighting ordinances.
Treat these as an additional compliance layer rather than a substitute standard. A design that satisfies EN 12193’s lux and uniformity table can still fail a CIE-based obtrusive-light review if aiming and shielding aren’t addressed separately.
Key Sports Lighting Metrics
A sports lighting design should not be evaluated using average lux alone. The following metrics work together to determine whether players, officials, spectators and cameras can see the activity clearly.
Horizontal Illuminance (Eh)
Horizontal illuminance measures the light falling onto the playing surface, normally in lux. It is one of the main values used when assessing training fields, recreational courts and non-broadcast competition venues. Average horizontal illuminance describes the overall lighting level, but it does not reveal whether some areas of the field are significantly darker than others — see Uniformity below.

Vertical Illuminance (Ev)
Vertical illuminance measures light falling onto vertical surfaces such as players, balls and objects viewed by spectators or cameras. It becomes particularly important in professional venues and television-broadcast projects — a field may have sufficient horizontal illuminance while players’ faces and the ball remain difficult to see from certain camera directions. Broadcast projects may evaluate vertical illuminance from several defined directions rather than relying on one horizontal lux result.
Lighting Uniformity
Uniformity describes how evenly light is distributed across the playing area. The most common calculation compares minimum illuminance with average illuminance:
General Uniformity: U0 = Emin / Eavg
Some standards also reference U1 = Emin / Emax (minimum-to-maximum) for stricter applications. A higher value indicates a smaller difference between the darkest and average areas. Good uniformity does not mean every calculation point has exactly the same lux value — it means dark zones, hotspots and sudden brightness changes remain controlled. The exact definition and required threshold vary by standard and by sport; always confirm which ratio a spec is referencing before designing to it.
Maintained Illuminance
Maintained illuminance is the lighting level expected after accounting for lumen depreciation, dirt accumulation and the planned maintenance cycle. Sports lighting compliance should normally be evaluated using maintained illuminance rather than the initial illuminance measured when fixtures are new — a system that only reaches the required lux level on day one may fall below the project requirement after operating for a period of time.
Glare Rating (GR)
Glare occurs when high-intensity luminaires enter the visual field of players, officials or spectators. EN 12193 uses Glare Rating (GR) to evaluate glare in many outdoor sports applications — a lower GR value generally indicates better glare control. Average illuminance may meet the project target while the venue remains uncomfortable if floodlights are positioned or aimed incorrectly. Glare control is especially important in sports where players frequently look upward, including football, tennis and basketball.
Colour Rendering (CRI) and Colour Temperature (CCT)
CRI describes how accurately colours appear under the lighting system. CCT affects the visual appearance of the venue — many facilities use neutral or cool white light, though the final specification should follow the applicable project requirements. Professional recording and broadcasting may require higher colour-rendering performance and tighter colour-variation control between fixtures.
Flicker Performance
Flicker may not always be obvious to the human eye, but it can become visible during slow-motion recording or high-speed camera operation. Where television coverage or professional video recording is required, the lighting specification should include suitable flicker-performance requirements before drivers and fixtures are selected.
Football / Soccer Field Lighting Standards
| Class | Illuminance (Eh) | Uniformity (U0) | Typical Use |
|---|---|---|---|
| Class I | ≥500 lux | ≥0.7 | International/national competition, broadcast |
| Class II | ≥300 lux | ≥0.7 | Regional/club competition |
| Class III | ≥200 lux | ≥0.5 | Recreational, training, school |
For FIFA-sanctioned broadcast events, requirements go beyond EN 12193’s baseline Class I — FIFA’s international broadcast standard targets approximately 2000 lux with a uniformity ratio of 0.8 or better and CCT between 5000K–5700K. This is an additional broadcast-specific overlay, not part of the standard EN 12193 class system itself. Broadcast specifications also place greater emphasis on vertical illuminance, uniformity across different camera directions, colour rendering and flicker performance — the applicable FIFA, UEFA or broadcaster requirements should be confirmed separately for each project.
From our engineering support team: In RFQs for regional (Class II) stadium and club-level football projects, the most common spec gap we see isn’t the lux target — it’s uniformity. Buyers often size fixture count and wattage purely to hit the average lux number, then find during commissioning that corner and touchline zones fall short of the ≥0.7 requirement. Confirming pole layout and beam angle against the uniformity target — not only the lux target — before ordering avoids most of this.
For early project planning, provide field dimensions, playing level, spectator requirements, camera requirements and applicable regional standard before fixture quantity or wattage is determined.
Tennis Court Lighting Standards
| Class | Illuminance (Eh) | Uniformity |
|---|---|---|
| Class II | ≥300 lux | — |
| Class III | ≥200 lux | ≥0.5 |
Indoor recreational courts typically require a higher baseline (around 300 lux minimum) than outdoor recreational courts. Recreational outdoor courts, club courts and professional competition venues should not be designed to the same lighting target — higher competition levels normally require increased illuminance and better uniformity.
Glare is especially important in tennis because players frequently look upward when serving or following a high ball; floodlights should not be positioned directly within the most common serving and return sightlines. The background behind the ball also affects visibility — excessive brightness differences between the playing area, surrounding structures and dark outdoor backgrounds can make the ball harder to track even when the average lux value is acceptable.
Swimming Facility Lighting Standards
EN 12193 covers different swimming disciplines separately because racing, diving, water polo and artistic swimming have different visual requirements. The required reference area and lighting performance depend on the activity type and competition level — diving and televised events may require additional consideration of vertical illuminance, judging visibility and camera directions.
Water surfaces also create reflections that can affect athletes, officials and spectators. Fixture position and aiming should be evaluated carefully rather than selecting one general lux target for every swimming facility. Because these sub-category requirements are detailed and facility-specific, a qualified lighting designer should confirm the exact figures for your pool type and competition level before finalizing a layout.
Ski Slope Lighting Standards
Ski slope lighting is also governed by EN 12193, with requirements structured differently from field-sport standards:
- Total slope area illuminance must reach at least 75% of the main (principal) area’s illuminance level
- Uniformity across the total area must reach at least 75% of the main area’s uniformity
- Glare Rating (GR) should not exceed 55
Fixture aiming is particularly important for ski slopes — floodlights must be positioned to reveal surface texture for skier safety while avoiding direct glare into skiers’ line of sight.
From our engineering support team: For ski resort projects, glare complaints tend to surface after the first season of night operation, not during design review — resorts commonly come back requesting reduced downhill glare once skiers report discomfort at higher speeds. Specifying adjustable tilt brackets at installation, rather than fixed aiming, gives resorts room to fine-tune this later without re-mounting fixtures.
Golf Lighting Standards (Driving Range)
EN 12193 covers defined golf practice areas such as driving ranges — not full 18-hole course lighting:
| Class | Illuminance on Tee | Illuminance on Distance Marker |
|---|---|---|
| Class III | 100 lux | 50 lux |
A driving-range design must consider more than illuminance at the tee — players also need to follow the ball over distance and identify landing or distance-marker areas. The design should evaluate light distribution along the ball trajectory, glare toward players, spill light beyond the range, and surrounding residential or environmental conditions.
There is no unified international standard specifically covering full golf course fairway or green lighting. A full course should not automatically be designed to driving-range targets — course-wide lighting projects should be evaluated on a site-specific basis with a lighting simulation.
Basketball Court Lighting
Basketball lighting requirements depend on whether the court is used for community recreation, club training, competition or professional broadcasting. The design must consider average illuminance, uniformity and glare because players frequently look upward while shooting, rebounding and tracking the ball. Outdoor courts near residential buildings also require careful spill-light control — meeting the required court illuminance does not guarantee a successful project if the floodlights disturb nearby residents.
Basketball court layout, pole position, mounting height and glare control — including FIBA-specific lux levels — are covered in detail in our Basketball Court LED Floodlight Design Guide. This section is intentionally brief because this article covers cross-sport standards rather than the complete design of one individual sport.
Skatepark Lighting — Industry Practice, Not a Formal Standard
Unlike football, tennis or swimming, skatepark lighting is not currently covered by EN 12193 or another widely recognized international lighting standard.
Common industry practice targets approximately 100–200 lux with good uniformity and glare control, but this is a general design reference — not a certified standard requirement. For skatepark projects, a site-specific lighting simulation is recommended over reliance on a fixed lux target.
How to Apply Sports Lighting Standards to Your Project
The applicable standard should be confirmed before selecting fixture wattage or preparing a commercial quotation.
1. Identify the sport. Confirm the exact sport and playing area — different sports use different reference areas and performance criteria. A multi-use facility may require more than one operating mode or lighting target.
2. Confirm the level of play — recreational, school/training, club, regional, national/international competition, or professional television broadcasting. The lighting class should be based on actual venue use, not the highest class by default.
3. Confirm the applicable standard. Check which standard, tender specification or governing-body requirement applies. EN 12193 may be the main reference, but national standards, federation requirements, CIE guidelines (see above) or contract specifications may add further conditions.
4. Define the performance targets — maintained average illuminance, minimum illuminance, uniformity, glare limit, colour rendering, colour temperature, vertical illuminance, flicker performance, and spill-light restrictions. Not every project needs all of these, but each should be reviewed before design begins.
5. Confirm the site conditions — field dimensions, pole positions, mounting heights, surrounding buildings, spectator or camera positions, nearby residential buildings, operating hours, site boundaries, trees/structures, environmental restrictions, existing poles, and electrical supply conditions.
6. Run a photometric simulation using the IES files for the exact fixtures and optical distributions being quoted, with the correct calculation grid, maintenance factor, pole coordinates, mounting heights and aiming directions.
7. Review the complete result — not average lux alone. Check uniformity, glare, darker boundary areas, fixture aiming, and unwanted light outside the sports facility.
8. Plan on-site verification. The measurement grid used during commissioning should match the grid used in the design calculation — otherwise the measured result may not be directly comparable with the simulation.
For fixture selection based on these targets, see our Wattage Guide, Beam Angle Guide and Mounting Height Guide.
Common Sports Lighting Mistakes
- Treating one lux value as universal — there is no single Class I, II or III lux value that applies to every sport; the sport-specific table must be checked.
- Designing to initial illuminance instead of maintained illuminance — ignoring lumen depreciation and maintenance conditions may cause the system to fall below the required level during its service life.
- Checking average lux only — an acceptable average can hide dark corners, over-bright central areas and poor minimum illuminance; uniformity across the full reference area must also be reviewed.
- Ignoring glare — high average illuminance doesn’t guarantee good visibility if fixtures sit within common player sightlines.
- Using the wrong calculation grid — different sports and standards define different reference areas and grids; an incorrect grid produces results that don’t match the acceptance method.
- Mixing EN 12193 with broadcast or CIE requirements without treating them as a separate, additive layer.
- Selecting fixtures before confirming the standard — starting with a fixed wattage or quantity can lead to under-lighting, wasted energy, or poor uniformity; confirm the target and site conditions first, then select fixtures through simulation.

Frequently Asked Questions
What is EN 12193?
EN 12193 is a European standard covering lighting requirements for many indoor and outdoor sports facilities, addressing illuminance, uniformity, glare and colour rendering, organized into three classes based on competition level.
Is EN 12193 the same as IES RP-6?
No. IES RP-6 is the North American standard for sports and recreational area lighting, using a four-class system (Class I–IV) with different numeric thresholds than EN 12193’s three-class system.
Do all sports require the same lux level for the same class?
No. EN 12193 lux requirements vary significantly by sport — Class I football requires 500 lux, while Class I horse racing requires only 200 lux.
Is average lux enough to approve a design?
No. The design should also evaluate minimum illuminance, uniformity, glare, maintained performance and any required vertical illuminance — an acceptable average lux value can still hide dark areas and uncomfortable glare.
What’s the difference between EN 12193 and FIFA broadcast standards?
FIFA broadcast requirements (around 2000 lux) sit above EN 12193’s baseline Class I football requirement — an additional overlay for televised professional matches, not part of the standard EN 12193 class system.
Do I need to consider CIE standards in addition to EN 12193?
Only if your tender or project scope calls for it — typically for broadcast coverage (CIE TR 83) or when glare/light spill near residential areas is a concern (CIE 112/150). These sit alongside EN 12193, not in place of it.
Why is maintained illuminance important?
Light output decreases over time due to LED lumen depreciation, dirt accumulation and other operating conditions. Maintained illuminance represents the lighting level expected after these factors are considered, making it more appropriate than initial illuminance for long-term compliance.
Is there an official standard for skatepark lighting?
Not currently. Skatepark lighting typically follows general industry practice (around 100–200 lux) rather than a certified standard.
Conclusion
Sports lighting compliance starts with identifying the applicable standard, lighting class and sport-specific requirements — not with selecting a fixture first. Average illuminance, uniformity, glare, maintained performance and any broadcast or CIE requirements should be evaluated together before the final lighting configuration is approved.
