My school currently has four followspots: 3 altman 902 and one that I believe is made by Little Stage Lighting. Two of them are sitting on floor stands at the back of the house, at about a 20-30 degree vertical angle from the stage, and about a 30 degree plan angle (they're on the two sides, because there are architectural obstructions in the center). The other two (both altmans) are not being used. We would like to put two or three of the spots in our catwalk beam position, which has a 40-50 degree vertical angle to the stage. My question is threefold: 1: How do you recommend we mount the suckers? Our catwalk is equiped with a wierd mounting system made by electro controls called a channel mount, it's similar to unistrut, just more of a pain to work with. Basically, we need a way to suspend the spot from a piece of threaded rod or a bolt. Currently, we have three floor stands, but they're open at the top, so they would be completely useless for underhanging the spots with. 2: This is more a design question, but where do you recommend we place them? We have space to hang two dead center, but without any available circuits (we'd have to run a jumper) and one about 35 degrees left of center with a non-dim circuit, and another the same distance right of center, also with a non-dim. We would like to keep at least one spot located in the house for outside events, so that we don't have to bring people up to the catwalk where they could cause damage, or hurt themselves, or fall through the ceiling, etc. 3: all three of the altman units have a cooling fan, so they can't be easily placed on a dimmer, but the little stage lighting one is fanless. However, it is currently using a 1500W Quartz-Halogen lamp, and our dimmers are only 1.2kW. The altman that we are using has the same 1500W halogen lamp, and the other two have 1500W incandescant lamps. Would it be feasible to put 1000W lamps in the spots so that they can be dimmed? It occurs to me that since we are greatly reducing the throw distance, the 1500W lamp might be too bright anyways. What kind of lamp would we want to use? They are currently using a mogul pre-focus base. Also, what kind of wiring would we have to do to bypass the fan and allow the lamp to be dimmed in the altman units?
