If the stadium design or existing installation requires luminaires to be positioned within a lateral distance of 20° perpendicular the goal line (in blue above) or if the vertical illuminance requires improvement, a second linear array of luminaires should be used to achieve the required vertical illuminance along the goal line and within the penalty area. Luminaires positioned directly behind the penalty area should be mounted at an angle of more than 60° (in red above). Outside the area parallel to the penalty area, luminaires may be mounted at an angle of more than 45° (in green).
Where possible, all luminaires behind the goal line should at least 20m above the pitch surface. If this is not possible, it is important to develop a design solution that considers the implications of that reduced height.
