Outdoor Site Lighting Performance
The LRC developed Outdoor Site (Lighting) Performance, or OSP, a framework for quantifying light pollution from an installation. OSP is the first comprehensive, quantitative system of assessing light pollution based upon the concept that property owners should be able to meet their lighting design objectives while adhering to light pollution regulations set by their communities. OSP uses a calculation ‘shoe box’ that follows the boundaries of a property and a top plane.
