ESTIMATING MAXIMUM SPACING

Ideally, all light energy produced would be focused into desired "lighted" zones with no wasted energy being directed elsewhere. This would require an infinite array of distributions, with the ability to tune them to every site condition.

While this is not realistic, the combination of careful luminaire selection, mounting height, and huminaire placement, can produce very efficient designs, using just four basic distribution patterns.

For each of the basic distributions, variations such as range and the characteristics of horizontal vs. vertical lamp optics, produce additional choices. …
