High-performance lighting for professional & recreational sports
Sports Facilities
Sports lighting is the most demanding subset of outdoor design. The photometric brief is unforgiving — average illuminance, uniformity, glare rating, and CCT all defined to a tighter tolerance than any other outdoor application — and the geometry is fixed by the playing field. EN 12193 sets the framework for European sports lighting and divides every venue into three classes: III (training and recreation), II (club competition), and I (top-flight competition with broadcast). The class drives every downstream decision.
How we approach sports facilities.
Illuminance and uniformity
EN 12193 sets average horizontal illuminance targets per discipline and class. Football, the most frequent brief in Cyprus, runs 75 lux for Class III (training), 200 lux for Class II (club competition), and 500 lux for Class I (top division and broadcast). Tennis, volleyball, basketball, and athletics each have their own target tables.
Uniformity (U₀ = E_min / E_avg) sits at 0.5 for Class III, 0.6 for Class II, and 0.7 for Class I. Hitting U₀ ≥ 0.6 on a full football pitch is non-trivial — it requires a careful balance of mast positions, asymmetric reflectors, and individual luminaire aiming, all modelled in advance with photometric software.
Glare and the residential edge
Glare rating (GR) per CIE 112 is the metric that constrains how the venue affects players, spectators, and any residential property within line of sight. EN 12193 caps GR at 50 for sports lighting; values approaching 60 are perceived as disabling. Asymmetric reflectors with internal louvres, careful aiming away from the principal viewing direction, and back-light shields toward residential edges keep the design within the cap.
Spill light onto neighbouring properties is the more frequent source of friction. CIE 150 environmental-zone limits apply: most Cyprus sports venues sit in E2 or E3, capping luminous intensity into adjacent windows at 7,500 or 10,000 cd respectively. The design tool is shield placement and aiming discipline, not raw luminaire selection.
Mast geometry and luminaire choice
A standard four-mast football scheme places masts at the four corners of the pitch, set back 5–15 m from the touchline and goal-line. Mast height is driven by the aiming angle: a maximum aiming angle of 65° from the vertical at the far corner of the pitch keeps glare and uniformity in spec. For a Class II 100 × 64 m pitch, this typically means masts at 18–22 m.
Luminaire selection is class-driven: high-output LED engines with internal asymmetric reflectors, individual aiming, and integrated visor/louvre options. Most modern fittings offer 1° aiming resolution and per-luminaire dimming, which means the same hardware can serve a Class III mid-week training session and a Class II weekend match by switching scenes.
Standards and compliance
EN 12193 (Light and Lighting — Sports Lighting) is the principal European standard. CIE 112 covers glare rating. CIE 150 covers obtrusive light. BS 5489-3 references the same EN 12193 framework with UK-specific guidance. Federation-specific requirements (UEFA, FIBA, World Athletics) layer additional broadcast-class targets on top of EN 12193 Class I and apply to top-tier venues only.
What every brief asks us.
- EN 12193 class selection (III / II / I) drives every other decision
- Uniformity (U₀) ≥ 0.5 / 0.6 / 0.7 by class
- Glare rating (GR) ≤ 50 per CIE 112
- Asymmetric reflectors with shields toward residential edges
- Mast height set by 65° max aiming angle to far corners
- Multi-scene control to serve training and competition from the same plant
Common questions.
- What's the difference between training-grade and competition-grade sports lighting?
- EN 12193 separates training (Class III) from club competition (Class II) and top-flight broadcast (Class I). The headline difference is illuminance: 75 lx, 200 lx, and 500 lx respectively for football. Uniformity and glare-control targets also tighten with each class. The same fixture hardware can serve multiple classes through dimming and scene control.
- How is spill light onto neighbouring properties controlled?
- CIE 150 sets limits on luminous intensity into windows of nearby properties — typically 7,500 cd in suburban zones (E2) and 10,000 cd in light-urban zones (E3). The design tools are asymmetric reflectors aimed away from the residential edge, dedicated back-light shields on the affected fixtures, and careful selection of mast positions during the photometric model phase.
