So, the newly renovated theater at a local HS where I help out has bunch of nice, new Strand SL 19-degree for the FOH loghting position...
The problem we're having is that there is a sloped ceiling above the lighting position, that is parallel to the beam of the fixture (when focused on stage) and about 5 feet above the beam. There is a LOT of "spill" from the front of the instrument, which is doing a good job of lighting up the ceiling. It's almost as if light is being reflected sideways from the inside of the barrel.
Has anyone else seen this behavior? Is this something unique to the SLs? Or, is this a ususal problem with Ellipsoidal fixtures, and I just hadn't noticed before?
