Light Calc is a photometric calculation tool for professional lighting designers and theatrical electricians. It allows you to carry a pocket database of commonly used theatrical lighting fixtures that you can quickly access in the field. Light Calc allows a user to select a type of lighting fixture, choose one of several lamp types, and set a throw distance. The calculator will then return a beam diameter and field diameter, in feet, as well as center field illumination, in footcandles.
