When pitch illuminance is provided by means of corner columns or towers with multiple luminaires in a group (as is generally seen in columns and towers), the luminaires should not be mounted within 15° of either side of the goal line (see diagram above).
Large multiple arrays of luminaires provide greater levels of discomfort glare and should not, therefore, be positioned in these areas. For this purpose, a consecutive line of luminaires with more than two rows is considered, to be a ‘large multiple array’.
