I have a problem with a light. The problem started last night, about five minutes before house opened. The light (a fresnel, if that makes a difference) started flickering during the curtain warmer cue, of which it is NOT a part. When I tried to patch it at 00 intensity, it stayed on. So I checked the dimmer, where nothing seemed wrong. I turned the dimmer off and back on, and the light just stayed on. I checked the lamp (I made sure it was seated correctly in the light) and thought about replacing it, when my SM said that house was opening in two minutes...so I unplugged it the light and left it like that for the show. I'm told that the absence of that light doesn't make a noticable difference, so I'm considering leaving the light unplugged for the last two shows. But I still want to know what the heck is going on. I'd probably have a better idea if I had taken an actual lighting design class, but my school's theatre department doesn't offer one. House opens in an hour, so I might figure something out, but my solution for the moment is to leave it out completely.
