Lux targets vary by level of play and standard-but the decision logic is repeatable. This guide shows how to set sport-appropriate targets fast, avoid over-engineering, and write enforceable acceptance rules.
Use the sport table to identify must-have metrics (Eh, uniformity, GR, Ev, flicker), then lock the measurement method so the targets are defendable at sign-off.
- Key takeaway #1: Decision chain: sport → level (training/competition/broadcast) → standard/tender → acceptance method.
- Key takeaway #2: Tennis and baseball are often more Ev-sensitive; football/rugby often more boundary spill/glare sensitive.
- Key takeaway #3: Multi-sport venues succeed when you design for the toughest tier and use control modes for the rest.

When this applies
Use this guide when you need to set performance targets quickly for a tender, a distributor quote, or an early-stage feasibility check. It helps you avoid two costly mistakes: over-engineering (too expensive) or under-specifying (fails acceptance).
Typical scenarios
- Early RFP stage: you need sport-appropriate target logic before full calculation.
- Multi-sport venues: one system must cover multiple sports with different sensitivity to glare/Ev.
- Retrofits: poles are fixed; you must match targets via optics + aiming + controls.
- Distributor quoting: you need a defendable “why these targets” explanation.
Key requirements / metrics
This table highlights what actually drives design decisions sport-by-sport (beyond average lux).
| Sport | What drives the design | Typical decision focus | Common pitfalls |
|---|---|---|---|
| Football (soccer) | Large rectangular area, long viewing distances, community spill/glare risks. | Eh + uniformity + GR; add Ev + flicker if broadcast is required. | Over-powering average lux while ignoring glare and spill at the boundaries. |
| Tennis | Fast ball tracking, player sightlines often close to luminaires. | Glare control + useful vertical component; mounting height and aiming are sensitive. | Using wide optics and high tilt that puts bright sources in player eye lines. |
| Baseball / Softball | Ball in air and high vertical visibility; infield/outfield differences. | Ev planning + uniformity zoning; avoid extreme hot spots in infield. | Designing only for Eh on the ground; fly-ball visibility suffers. |
| Rugby | Similar to football geometry; frequent high-ball play and wide viewing angles. | Eh + uniformity + GR; ensure edge control for touchlines and run-off. | Ignoring edge zones and assuming football targets automatically fit rugby tenders. |
Definitions
“Lux targets” should never be picked by sport alone. The correct chain is: sport → level of play → adopted standard/tender → acceptance method. The most common confusion is treating a broadcast stadium target as if it were required for a training facility.
Typical target ranges
Because numeric lux targets vary by standard and tender, the safest “typical range” guidance is by project tier:
- Training / recreational: often in the low-to-mid hundreds of maintained lux, with practical uniformity and glare comfort.
- Competition: typically moves into the mid-to-high hundreds with stricter uniformity and glare limits.
- Broadcast / elite: often requires ~1000 lux and above plus Ev and flicker criteria, and tighter glare/spill control.
Use the table above to decide which metrics become “must-have” for your sport (e.g., tennis/baseball are more Ev-sensitive). Then confirm exact targets from the tender.
Step-by-step workflow
The fastest way to set targets without over-engineering is to separate the venue into use tiers and define “must-have metrics” per sport.
Inputs to collect (must-have)
- Sport(s) and level: training / club / competition / broadcast.
- Standard reference: tender, local federation, EN practice, or broadcast guideline.
- Pole data: mounting heights, locations, tilt limits, and constraints.
- Constraints: glare/spill limits, neighbors, roads, curfew.
- Controls: do you need training/match/event modes to cover multiple sports?
Design decisions (key points)
- Design for the most demanding sport tier. Then use dimming/modes for lower tiers.
- Define Ev early for tennis/baseball/broadcast. It’s often the hidden requirement behind “good playability.”
- Use optics as your ‘targeting system’. One housing + multiple optics can cover different sports on the same poles.
- Write acceptance rules now. Targets without a grid/method are not enforceable.
Verification & sign-off (how to accept)
- Report package: include targets, grid/areas, assumptions, and pole-by-pole aiming tables.
- Site test plan: align measurement points with the report; record aiming and conditions.
- Mode validation: if multi-sport modes exist, verify each mode output and scene works as intended.
Common mistakes
- Picking lux by sport only: level of play and standard determine the target, not sport name alone.
- Over-engineering every field as broadcast: wastes budget and can increase glare/spill risks.
- Ignoring Ev for tennis/baseball: playability and camera results suffer even if Eh is high.
- No control strategy: multi-sport venues need modes (training/match/event) to optimize energy and comfort.
- Missing acceptance method: targets must be tied to grid/area and commissioning procedure.

FAQ
Are lux targets the same worldwide for each sport?
No. Targets depend on the adopted standard (local federation, EN practice, or broadcast specifications), the level of play, and whether video/broadcast is required. Use 'sport + level + standard' as the decision chain.
Why do tennis and baseball often feel more demanding than football?
Because visibility is more sensitive to the ball in air and viewing directions. Tennis and baseball often benefit from stronger vertical illuminance control and tighter glare management.
Can one lighting system cover multiple sports on the same field?
Often yes, if the optics set and control modes are planned early. The key is to design for the most demanding sport and use dimming/modes for others.
Do higher lux targets always mean better quality?
Not necessarily. Uniformity, glare control, and vertical illuminance can matter as much as average lux—especially for player comfort and camera results.
What is the fastest way to avoid over-engineering lux targets?
Confirm the required level of play and whether broadcast is included, then match the design to that target—rather than designing every venue like a TV stadium.
