Many countries have regulations and guidelines aimed at ensuring that the amount of stray illuminance does not have an undue impact on the local community.
The type of stadium structure and pitch illuminance system will determine the level of illuminance that is produced in areas outside the stadium. A report should be produced based on adequate reference points in areas around the stadium and showing the illuminance levels created by the pitch lighting system on the horizontal and vertical planes. The report should comply with the guidelines from the relevant authorities and be submitted to them for approval.
For reference purposes, pitch illuminance systems should not produce illuminance levels greater than 50 lux on the vertical plane at a height of 1.5m and a distance of 50–200m from the stadium perimeter. In the case of lower-illuminance level stadiums, the stray light from the pitch illuminance system should also be lower.
