Divine Lightings' Guide to Understanding Light Distribution:

What is Light Distribution?

Light distribution, or more specifically lighting optics, refers to the design and use of lenses, reflectors, and other tools that control how light is directed or spread. These optical components shape the light to achieve specific effects, such as focusing it into a beam, spreading it evenly, or directing it in a certain direction. For example, a sports arena will want to concentrate light onto playing surfaces to give athletes the best opportunity to see the fast action and fine details of the play that is progressing around them, without stray beams blinding spectators in the stands. Large outdoor parking lots will prefer lighting that illuminates the entire lot uniformly, with no dark areas or shadows that might make motorists uncomfortable.
