The Interfit Honeycomb Grid for 27" Beauty Dish is dedicated to the INT249 27" (68.6 cm) reflector, commonly called a beauty dish. The shallow, flat profile of the reflector yields crisp but diffused light. The grid concentrates the output, narrows the beam spread and controls spill light. The INT249 reflector itself is specifically made for the "EX" family of products. It fits products with an EX fitting including Interfit EX150, EXD200, EX300 and EXD400.
