Abstract
An assembly of LED luminaires is distributed at a sports venue, includes key, back, and fill light sources in such a way as to provide modeling within a significant portion of the playing area of the sports venue, uses beam types narrower than previously used, and achieves efficiencies higher than previously attained, while also reducing glare and spill light.
