Field Template Beam Spread Stencil is a beam angle monster on steroids. It packs two sets of lighting symbols, divided into two scales, and aligned with three special protractors. That package is then combined with a catalog of manufacturer’s cut sheets and reference formulas into a single piece of plastic about the size of a piece of paper. The end result? This template can draw the edge of any light beam up to 180 degrees, and combined with a distance, can calculate the beam pool width for any light beam up to 90 degrees.
