Stage Lighting Calculator

Stop doing "napkin math" and start designing with precision. Stage Lighting Calculator is the first mobile tool built for the modern Lighting Designer. While other apps give you generic geometry, we give you real-world performance data. Simply select your fixture—like the Chauvet Ovation E-910FC—and choose your lens tube. Our engine instantly interprets manufacturer lumens and beam angles to give you the data that actually matters on a hang: True Coverage: See the exact diameter of your beam and field spread at any throw distance. Brightness at Target: Know your Footcandles or Lux before you even power on the rig. Perfect Lens Selection: Not sure if you need a 19° or 26°? Compare them side-by-side to see which fits your trim height. Multi-Profile Database: Includes profiles for industry-standard Lekos, Fresnels, and LED Pars. Built by LDs, for LDs. Whether you’re in a theater, a house of worship, or on a corporate gig, get the right light in the right place, every time.
