The Paul C. Buff Honeycomb Grids are a set of four Honeycomb Grids: 10º, 20º, 30º, and 40º. The grids will snap directly into the outer lip of the standard 7AB/R 7-inch reflector of the AlienBees B800 and Einstein E640 Studio Flash, narrowing the beam spread from the standard 80º. This set is perfect for spotlight, hairlight or emphasis light.
