(May also be spelled as "hexcel".) A device used to control light flare or spill 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, or any number of architectural lighting fixture suppliers.

Unit does a slightly better job of controlling spill than an egg crate louver due to less variation in the size of the opening (i.e., the max./min. opening in a hexagonal opening varies less than the max./min. opening in a square egg-crate).
