I have just completed a run of "The Witches of Eastwick" Act 1 finishes with a flying scene. Very wisely the production decide to build some trolleys with stands on. The Witches stepped back off Rostra and onto the footsteps of the trolleys which were about 4 feet off the ground ( 1.2metres ). The Director was keen that the trolleys not be seen. There was a base on the trolley which came forward about 1.5 meters (5 feet) and I put 12 volt birdies powered by motor cycle batteries. 12v / 8 amp hour. The birdies were 50w so two of them drew 8 amps at 12v and only needed to be on for about 7 minutes. Flying effect where the lights remained focused on the ladies wherever the trolleys went with no cabling to trip over. The only problem was that I had to rely on floor crew to turn the lights on at the right moment and it never once happened all at the same time despite very strict calling by the SM. My question: Have any of you guys come across a DMX operated 12volt dimmer I could rig with a wireless DMX system if I ever have to do this again. (Or even a 12 volt DMX operable solenoid switch I guess also with a wireless DMX. I have only just thought of that.) I would prefer the dimmer though I think.
