EDDUS RAY Posted March 24, 2012 Share Posted March 24, 2012 I was looking at the photometric data for the Source4 and it displays two different beam diameters for the light.. Does anyone know the difference between Field Diameter and Beam Diameter? http://www.jfrost.com/ent-tech/sales/lighting/Ellipsoidal/S4_26_vE.pdf thanks.
