Osram:New Goals for LED Stadium Lighting

Aside from increasing the visual playing conditions for both players and spectators, as well as minimising shadows, stadium lighting is also under strict guidelines enforced by associations such as Union of European Football Associations. This guarantees that experiences of those watching a match on television have the same viewing experience as those watching inside the stadium. If football is truly seen as the “beautiful game”, then the necessity to provide audiences consistent and true-to-life visual experiences is crucial.
