Indoor sports hall lighting is a balancing act. Raise the light levels for high-speed play and you risk glare; soften the glare and you may drop below the lux or uniformity a sport demands. The metric that reconciles the two is UGR — the unified glare rating — and getting it right is what separates a hall that feels comfortable from one that players dread. This guide covers the essentials of indoor sports hall lighting: lux requirements per sport under EN 12193, what UGR 19 versus UGR 22 really means, how to build a gymnasium lighting layout that controls glare, and how dimming lets one hall serve many sports.

Lighting Requirements by Sport: Lux, Uniformity and UGR
The reference standard for indoor sports lighting in Europe is EN 12193 (Light and lighting – Sports lighting). It classifies each sport by level of play — and the numbers are not equal across disciplines. Badminton demands the highest illuminance of any indoor sport because the shuttlecock travels at extreme speed against a bright hall background:
| Sport | Recreational | Club / competition | High level / TV | Typical UGR max |
|---|---|---|---|---|
| Badminton | 300 lux | 750 lux | 750–1000 lux | 19 |
| Basketball | 300 lux | 500 lux | 750 lux | 22 (19 elite) |
| Volleyball | 300 lux | 500 lux | 750 lux | 22 (19 elite) |
| Table tennis | 300 lux | 500 lux | 750 lux | 22 |
| Indoor football / futsal | 300 lux | 500 lux | 750 lux | 22 |
| Gymnastics | 200 lux | 300 lux | 500 lux | 22 |
Uniformity matters as much as the average: EN 12193 typically requires U1 ≥ 0.6 and U2 ≥ 0.7 on the playing area, and for badminton the court should be lit uniformly because the shuttle can land anywhere. Vertical illuminance for visibility of faces and fast-moving balls also enters high-level designs.
UGR 19 vs UGR 22: What the Numbers Mean
UGR (unified glare rating) quantifies discomfort glare on a scale from about 10 (imperceptible) to 30 (intolerable). It is calculated from the luminaire’s luminance, its position in the observer’s field of view, the background luminance and the source’s solid angle. Key points for UGR requirements:
- Lower is better. UGR 19 is the usual limit for high-level indoor sports, especially badminton and table tennis; UGR 22 is acceptable for recreational multi-purpose use;
- A step of 3 units is a clearly perceptible change in comfort — so the UGR 19 vs 22 difference is a real, visible improvement, not a rounding detail;
- UGR is achieved through optics, not wattage: deep reflectors, honeycomb or micro-prismatic louvres and controlled beam distributions keep brightness out of the players’ line of sight;
- Indirect lighting components soften the ceiling–luminaire contrast and lower UGR, at some efficiency cost.
For indoor sports hall lighting, specify luminaires with certified UGR data from the manufacturer, and ask for photometric files you can verify in Dialux.
Gymnasium Lighting Layout for Glare-Free Illumination
A good gymnasium lighting layout delivers uniform light while keeping luminaires out of the critical sightlines — the upward glances of players tracking a ball or shuttle:
- Mount at 7–9 m in standard halls; higher mounting reduces glare but may require more fixtures or higher wattage;
- Use a symmetrical grid with a spacing-to-height ratio (SHR) around 1.0–1.3 to hold uniformity without hot spots;
- Light the court from both sides and, where possible, aim luminaires crosswise so beams run across the line of play rather than along it;
- Avoid fixtures directly behind baselines or service lines, where players look into them;
- Add louvres or anti-glare rings on units near the court perimeter, and keep perimeter areas at a lower level to reduce contrast glare;
- Verify vertical illuminance toward the audience and camera sides for multi-purpose and video use.
Multi-Sport Switching with Dimming and Scenes
Few halls are used for a single sport. A gymnasium may host badminton league matches on Monday, school basketball on Tuesday and a fitness class on Wednesday — each with different EN 12193 requirements. Modern LED systems solve this with dimming and preset scenes:
- 0–10 V or DALI drivers allow smooth, flicker-free dimming from 100% down to about 10%;
- Preset scenes switch the hall instantly between profiles: 750 lux for badminton, 500 lux for club basketball, 300 lux for training — all at the correct uniformity;
- Occupancy and daylight sensors can further trim output in unoccupied zones, cutting energy and heat gain in summer;
- Emergency battery packs integrated in a small number of luminaires provide backup without a separate system.
Because the control logic lives in the drivers, the same fixture can serve a 300 lux training session today and a 750 lux match tomorrow — flexibility that conventional lighting simply cannot offer.
UFO High Bay or Stadium Floodlight? Choosing the Fixture
Two Worldhand families cover most indoor sports hall lighting projects:
- LED High Bay UFO series — compact 100–300 W units with wide, symmetric distributions; ideal for standard halls with 7–12 m mounting heights, and easy to retrofit into existing sockets and track systems;
- LED Stadium Lights — higher wattage with narrower, aimable beam options; suited to tall halls, multi-court arenas and facilities that also light outdoor fields, so one product family can serve the whole site.
Choose by mounting height, hall geometry and beam-angle control. Certified UGR data, CRI ≥ 80 (90 for video), flicker-free drivers and IP65-rated housings are the non-negotiable checklist items.
FAQ
Why does badminton require the highest lux? The shuttlecock is the fastest-moving object in indoor sport, and players track it against a bright background. EN 12193 sets badminton at 750 lux for elite play, with high uniformity, so the shuttle is visible instantly at every point of the court.
What is the difference between UGR 19 and UGR 22? UGR is the unified glare rating; lower values mean less discomfort glare. UGR 22 is acceptable for recreational play, while UGR 19 — a clearly perceptible, roughly three-unit improvement — is specified for high-level competition, especially badminton, table tennis and televised events.
Can one lighting system cover several sports? Yes. With 0–10 V/DALI dimming and preset scenes, a single LED installation can switch between 300 lux training, 500 lux club play and 750 lux competition profiles at the touch of a button.
What mounting height is recommended? For standard gymnasiums, 7–9 m is the common range, giving good uniformity and manageable glare. Halls over 12 m call for higher-wattage units with narrow beams, such as LED stadium lights, to keep the light where the court is.
