Lux is a unit of measurement that indicates the amount of light that falls on a surface. It is commonly used to measure the brightness of a football stadium, which affects the visibility and comfort of the players, officials, spectators, and broadcasters. But what is the standard lux level for a football stadium, and how is it determined? FIFA Stadium Lighting Guide
The most authoritative source for the standard lux level for a football stadium is the FIFA Stadium Lighting Guide1, which provides best-practice guidance for any football stadium development, anywhere in the world. The guide specifies different illuminance levels for different categories of stadiums, depending on the level of competition and the broadcast requirements. The guide defines four levels of stadiums: Elite level A, Level A, Level B, and Level C. Elite level A stadiums are the highest standard, suitable for hosting FIFA World Cup™ final tournaments and other international televised events. Level A stadiums are suitable for hosting UEFA Champions League and Europa League matches, as well as national team matches. Level B stadiums are suitable for hosting domestic league matches and lower-level international matches. Level C stadiums are suitable for hosting amateur and recreational matches. The guide also defines four illuminance levels: Level D, Level E, Level F, and Level G. Level D is the highest standard, suitable for Ultra High Definition (UHD) and High Dynamic Range (HDR) broadcasts. Level E is suitable for High Definition (HD) broadcasts. Level F is suitable for Standard Definition (SD) broadcasts. Level G is suitable for non-broadcast matches. The guide provides the minimum and maximum values for the horizontal and vertical illuminance, as well as the uniformity and color rendering index, for each combination of stadium and illuminance level. The horizontal illuminance measures the light that falls on the playing surface, while the vertical illuminance measures the light that falls on the faces of the players and officials. The uniformity measures the consistency of the light distribution across the field, while the color rendering index measures the ability of the light to reproduce the colors of the objects.
