So when my show opens theres a special on stage, it lit up fine for the opening, but when it's used about 10 min. later it wouldn't come on. So I thought, "The lamp blew, no biggie." I change it at intermission and it's used first thing in act 2 it comes on fine at first, but then the second time it's used in act two it doesn't work. Now I have never seen anything like this, anyone have any thoughts?
