It is essential to ascertain the level of UEFA competition that the stadium is intended to be used for. The pitch illuminance system should be designed to meet the requirements of the relevant UEFA illuminance level. An illuminance system that operates to a higher specification than is necessary may be unduly expensive to install and operate. In some situations, it may even be considered inappropriate given the stadium’s size and location. However, it is also important that the design process gives due consideration to long-term aspirations in terms of the intended use of the stadium. In some cases, it may be preferable to comply with the requirements of a higher UEFA illuminance level to allow for future development.
Guidance in selecting the relevant UEFA illuminance level is provided in Overview of illuminance levels for UEFA competitions.
