George C. Smedberg consulted with Delford F. Brummer of Stanford University Theatre to develop the Westlite Projector in the 1990s. The Westlite Projector was an improvement on previous Linnebach projectors. It allowed for custom projections using paint on acetate sheets, but the projections had a soft focus. While large and sometimes difficult to hide, the Westlite Projector was still fairly dim. It helped advance projection technology but was later replaced by glass gobo technology.

LINNEBACH PROJECTOR-HELPED DEVELOP THE WESTLITE PROJECTOR Custom made projections using paint on acetate sheets of plastic. Soft focus projections only. Large piece of equipment, difficult to hide at times. Fairly dim. Largely replaced by glass gobo technology. Vern Reynolds — A Plea for Linnebach Projection 211 George Smedberg, a representative of the Associated Lighting Service of San Francisco, consulted with Delford F. Brummer, technical director of the Stanford University Theatre, to produce this instrument — The Westlite Projector. After a series of rigorous tests performed on the stages of Stanford's Memorial Auditorium using the Westlite Projector, I heartily recommend it as a definite step forward in Linnebach design.
