A way of controlling spill light from a fixture - Similar in function to an egg crate louver. The louver is typically made from lightweight metal, approximately 1/4 inch thick, with many hexagonal openings. First known use on Broadway by Abe Feder in the 1960s to control spill from beam projectors. Available on special order from City Theatrical. More often used in architectural than theatrical applications.
Unit does a slightly better job of controlling spill than an egg crate louver due to less variation in the size of the opening (IE the max / min opening in a hexagonal opening varies less than the max/min opening in a square egg crate).
