Stadiums must be equipped with a floodlighting system that allows to maintain at least the following average illuminance, measured according to the UEFA Lighting Guide:
Category |
Horizontal illuminance (Eh ave) |
Vertical illuminance (Ev ave) |
---|---|---|
1 |
≥350 lux or sufficient to allow the host broadcaster to ensure adequate broadcasting of the match |
|
2 |
800 lux with uniformity ratios of U1h >0.4 and U2h >0.6 |
350 lux on each reference plane with uniformity ratios of U1v >0.35 and U2v >0.45 |
3 |
1,200 lux with uniformity ratios of U1h >0.4 and U2h >0.6 |
700 lux on each reference plane with uniformity ratios of U1v >0.35 and U2v >0.45 |
4 |
1,400 lux with uniformity ratios of U1h >0.5 and U2h >0.7 |
1,000 lux on each reference plane with uniformity ratios of U1v >0.4 and U2v >0.5 |
The stadium floodlight system must be regularly maintained to meet the required minimum illuminance values. A lighting certificate that is valid for the entire competition period must be issued no more than one year before the date of the home team's first match in the UEFA competition concerned.
In addition, to ensure that matches can proceed in the event of a power failure, an independent backup power supply must be available and able to provide at least the following average horizontal illuminance:
Category |
For matches played under floodlights |
For broadcast matches |
---|---|---|
1 |
n/a |
n/a |
2 |
350 Eh(lux) |
350 Eh(lux) |
3 |
350 Eh(lux) |
800 Eh(lux) |
4 |
350 Eh(lux) |
900 Eh(lux) no more than 15 minutes after the power failure. |
A floodlighting power backup test must be performed at least once a year. Stadium emergency systems must be fully functional and comply with the country's health and safety norms and standards. To verify the correct functionality of the entire stadium, a full black building test is recommended every four years.
