That’s when I stumbled across their new OPTI-SCULPT Filters, which are specifically meant for precise beam shaping.

While considering solutions to my D60 coverage issues, I found myself browsing through all of the diffusion materials available on Rosco’s website. Adding R113 to spread the light vertically helped somewhat, but the same issues persisted.ĮTC D60 fixture with Wide Oval Lenses + R113 in the pit. Students standing at the top of the risers might be in the dark compared to at the bottom of the risers. While the beam spread left/right was sufficient, I found the coverage up/down was lacking. Choral risers are often placed in the pit during concerts, so it was important to have some dedicated coverage in that area.

I also specified three D60 fixtures with Wide Oval lenses to light the pit in front of the stage. Unfortunately, the beam did not spread up the grand curtain enough, or reach far enough to the front edge of the stage.ĮTC D60 fixture with Narrow Oval Lens on the main drape. I specified five ETC Desire D60 Lustr+ LED fixtures with Narrow Oval lenses to provide a soft general wash.

I took as much care as possible to specify appropriate lenses I relied on manufacturer data sheets and Vectorworks for visualization.

In designing the repertory rig, there was pressure to stretch the coverage of the fixtures we could afford to buy.

Fortunately, we were able to achieve an inventory of mostly ETC fixtures. Like many LED conversion projects, the goal for Norwich High School Auditorium was to purchase as many fixtures as the budget would allow without sacrificing on quality. Once he got the new LED fixtures in place, he realized that some of the beams needed adjustment and that Rosco’s new OPTI-SCULPT beam shaping filters were the solution. It’s one of the venues where he got his start in theatrical design, so he cared very much about how effectively the venue could support the theatrical arts and other events that occurred inside. When Matthew Grenier found out his high school was planning to convert its auditorium stage lighting to LED, he offered to consult on the design and implementation.
