# Sports lighting: aiming and uniformity

The governing metrics in sports lighting are uniformity and [glare](https://www.xingguanglightingcn.com/en/glossary#ugr), not total [illuminance](https://www.xingguanglightingcn.com/en/glossary#illuminance): amateur and professional levels set different bands for both, and uniformity comes from a four-corner layout with accurate aiming, not from more power. Five degrees of aiming error can put one touchline below the requirement.

## Key parameters

| Power | 300–1000 W |
| --- | --- |
| Mounting height | 12–20 m |
| Design illuminance | 200–750 lx |
| IP rating | IP66 |
| Beam angle | 15° / 30° / 45° |
| Distribution type | Asymmetric (four-corner layout) |

## The distribution decides where the light goes

Two fixtures with the same wattage and the same flux can put a twofold different illuminance on the floor, purely because of distribution. This page is Asymmetric (four-corner layout). Distribution decides three things: the shape of the pool of light, how much of the flux reaches the floor, and whether the spacing can be opened up.

A common misjudgement is comparing distributions by centre illuminance. A narrow beam usually wins at the centre point and loses badly at the edges, giving a lower average. Compare average illuminance plus uniformity (minimum over average) — those two numbers match what people actually see.

## Angle and height come as a pair

This page is 15° / 30° / 45° at 12–20 m. The direction is unambiguous: the higher the ceiling, the narrower the optic, or the light lands on the walls; the lower the ceiling, the wider the optic, or the floor gets discrete bright spots and hard shadows under each fixture.

Rule of thumb: pool diameter ≈ 2 × height × tan(half angle). At 10 m, 90° gives about 20 m and 60° about 11.5 m. Sketch the layout with that first and ask for a photometric calculation second — the other order usually costs a revision.

## Four things to verify before ordering

① Whether flux and efficacy are quoted for the complete fixture or the light source — a 10–15% difference that changes the fixture count. ② Whether [colour temperature](https://www.xingguanglightingcn.com/en/glossary#cct) and CRI are measured or nominal values; mixed CCT within one batch is the most common arrival dispute. ③ Driver brand and model, plus its derating curve at high temperature — it is the only part that really sets life. ④ The mounting kit list: chain, bracket and anchors in the box, or the site stops for a day.
