Lighting truss hanging in a theater with (from left to right) a Source 4 ERS, 2 Lekolite ERSs, a Martin MAC 550, and 2 more Source 4 ERSs. THe blue background is due to the cyc being lit with a night blue color gel. The cluser of 3 small lights at the bottom is a street light for the show that was running at the time the picture was taken.
