I am going to be purchasing new instruments to light our back wall with soon and I need your assistance. I am wanting to RGBA color mix on a 15'X34' cyc wall. It will be lit from 3rd electric, which is about 9' out taken to a 14' or 15' trim...obviously it can go higher or lower if needed. Money is somewhat of an issue as I will only have about 4-$5,000 to spend on lighting it. I am looking for a nice mix of thump while not burning out gels every show. currently I am looking at the altman 4 cell skycyc...not yet sure if I need 3 or 4 of them. what do you think?
