Evening CB, I will be doing a dance recital at my school districts brand new high school, which has a very nice looking theater! However, just getting in there today I found I have a bit more than I planned :neutral: Its running an Express 48/96 board and two sensor racks. Lighting rig is mainly comprised of no name fresnels with 750w lamps, 3 electrics of colorbars with RBGO, and an electric of 12 cyc lights, not sure on the brand/wattage. Their FOH catwalk is 9 Colortran 5/50's, I believe three 10°, six 20°. All with 1000w lamps:shock: . Now at the highschool I went we had S4's, all with 575w in them. Got their today to find the board is on a 1-1 patch, half of the fresnels were burned out, a row of colorbar was hooked up incorrectly and I was getting half orange half blue on the bar . Also, the entire FOH was burned up. I go up to take a look at the lamps and I had to remove the front lens because they had swelled larger than the reflector. And, there are no replacement lamps available in the building. It turned out to be a real PITA....but the real reason I posted here is I have a couple quick questions about this lighting rig. I have one dimmer that only responds when it is given intensity above 50%. What could be the cause, I remember seeing a similar topic earlier in CB but couldn't find it? Also, what lamp would you recommend to put into the 5/50 fixtures? The throw to stage is ~30ft, but it could be less. Also, these are often left on for hours at a time, but I am working to get that to no longer happen. -Cheers and thanks!
