Field Template - Beam Spread

The 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 slightly larger than a piece of letter-sized 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.

• Vertical centerline divides between 1/2" scale (Left) and 1/4" (Right)
• Internal protractor cutouts extend to 45° per side, allowing angles up to 90° to be easily drawn
• Vertical "gutters" along both sides extend from 24° to 90°
• Vertical centerline includes distance markers for both scales
• Three different dash cutouts provide additional line styles
• Conversion formulas to/from:

  • Feet & Meters
  • Lux & Footcandles
• Formulas for:

  • Pool Size Multiplier
  • Pool Diameter
  • Pythagorean Theorem
  • Candela
  • Footcandles
• Pool Size Multipliers for common degree angles and fixtures
• Designed to fit in a standard 3-ring binder, with the top slightly higher than standard pages (like a tab separator)
• Includes symbols for 1/4" and 1/2" drawings
