A method, apparatus and system for illuminating a sports field. The method includes identifying fixtures having a likelihood of affecting playability or glare or spill light relative to a point of view on or off the field. The method includes steps to identify such fixtures for the purpose of adding a component which improves playability or decreases glare or spill light for the point of view. A further method does so for multiple points of view relative to the field, whether on or off the field. One component is a long visor that would be added only to identified fixtures.
