Summary of Lighting Specifications for Football Televised Events
                       The following table is a summary of the criteria to be considered for televised events. It sets out the
                       recommendations for vertical and horizontal illuminance, uniformity and the colour properties of
                       lamps for each class of activity.

                       Notes:

                           Vertical illuminance refers to illuminance towards a fixed or field camera position.
                           Vertical illuminance uniformity for field cameras can be evaluated on a camera-by-camera basis
                           and variation from this standard will be considered.
                           In all classes, the glare rating is GR ≤ 50 for players on the pitch within the player primary view
                           angle. The glare rating is appropriate when the player view angles are met.
