Sharp Cutoff & Light Trespass
Spill light or light trespass is the light that illuminates surfaces beyond the property line. An example is the light on a bedroom wall coming through the window from the ball field across the street. A number of ordinances place limits on spill light near the property line as the sole means of controlling light trespass. The most effective way to minimize spill light from a location is to apply forward throw optics around the perimeter. Lithonia Lighting’s R4SC and SR4SC optics are designed specifically for this application.
