Hi there... Basic theory question for anyone who knows/remembers. I'm trying to spec some new instruments and repair some old ones (mostly 360q's), and what we have (all donated instruments), are way too short of a throw for our space, from any position, it seems. IIRC from my stagecraft class, many long years ago, and from my own experience and preferences...please check me if I'm wrong...or right... The best instrument to choose to light an area onstage from a given position (instrument = ellipsoidal) is one that will produce a 10 foot circle of light, i.e. a 10 foot beam angle, for that particular throw. Am I remembering that right? Seems like I am. Right now I'm working with 6x9's and 6x12's mostly. The 6x12's, from our most rear-of-house position (plaster line-plus-50-feet), put out circles big enough to light the whole proscenium, the floor, the ceiling, etc. I have the shutters almost completely closed off and the instruments up no more than half to 75% (575w lamps). Seems like a waste of instruments, doesn't it? 10' beam angle is optimum, right?
