To Ship/Steveterry/Jmabray/other "old-timers": Has anyone ever used such an animal? Those guys in Utah must have been smokin' some crazy mushrooms in the '70s! While perusing my recently acquired copy of Photometrics Handbook by Robert C. Mumm (which I'm slightly disappointed in, BTW), I came across this line of ERS fixtures which use a 500w or 1000w PAR64/NSP as a light source. According to the footnotes, for the 3201, 36°: "This unusual instrument uses a 500 or 1000 W. PAR 64 lamp for a source, with an 8x18 step lens to gather and concentrate the light, and an 8x4.5 lens to focus it." All use an 8x18 step lens, other models use 2x 6x16; 1x 8x11; 2x6x20; and 1x 6x18 as the final lens. Output for these fixtures seems dismal, even with the 1000w lamp, compared to the comparable 360Q EHG-750w. Cut sheets say they have a gobo slot, or you could order the iris model without shutters, but I can't imagine achieving a sharp focus without an ellipsoidal reflector. Should it even be called an ERS if it uses, by the lamp's definition, a parabolic reflector? This, from a more recent thread, may be a picture of the fixture: http://www.controlbooth.com/forums/facility/2347-post-pic-your-theater-tech-stuff-2.html#post133219 Once again, I applaud EC's ingenuity, and pity their demise. Anyone want to talk of the Parellipsphere, which was widely touted, though seldom seen, when I was studying stage lighting in college. Or of the audacity to name a control system the "Playmate" during Hugh Hefner's sexual revolution of the 1970s? Food for thought. Have a Grand Day!
