First off let's all agree that Compact Fluorescents are a TERRIBLE idea for a theater. But it's too late to change that. So two nights in a row now when the house lights come up at intermission two circuits don't turn on. They have been working perfectly up until now. The racks were set to the proper setting by the Strand guy a month ago... and until now they've been working perfectly. But now they just don't turn on at intermission. Tonight after the show they stayed off. I tried all kinds of things. I ran the cue that calls for them to come to 55%. They didn't turn on. I went to the stage manager's panel which has a small architectural dimmer. The console runs to the rack as ethernet. The architectural dimmer runs into the rack as the "DMX B" control channel. I selected Dim mode on the architectural and brought them slowly to full while the rack was calling for 55% (The system is set HTP). The other circuits all came to full, but the two circuits in question didn't turn on. I tried the on switch off switch on the architectural control panel. No luck. I flashed on and off while the console held them at 55... the working circuits pulsed from 55% to 100%. Using my computer that is on the network I was able to log onto the rack and check the dimmers directly. The rack said the dimmers were definitely on at 100% but the lights were still off. Turned off the console did a variety of things from different control stations... finally left everything turned off for about 5 minutes and then they worked from the architectural control. Any ideas besides buy some scoops to use as house lights? I hung some S4 PARs with XWFL lenses as a back up and they look pretty good. That'll probably be my solution. I'm guessing the answer is no, but will an incandescent lamp work in these sockets? Supposedly I have Mark 10 ballasts.
