ETC has track versions of the Source 4 mini available, which might be a reasonable option with their shutters, etc.Track lighting might work if I can find something that can be pretty narrowly aimed from 25' above the floor. For the initial shows, I'm curious about some rechargable lights to clip on the chairs. The 3D printed clips would take some design but might make it easier in the long run. I'd like to find those little panel nightlights that I could run off a battery. The emergency lighting will kick in if we lose power, so these would be irrelevant.
