The Impact Fabric Grid for Large Octagonal Luxbanx is an 84" light modifier that attaches quickly to the softbox's recessed front via touch-fasteners. The 40 degree grid narrows the beam spread from your softbox to control spill light and add directionality similar to a reflector, while maintaining a soft quality of light. Unlike unwieldy rigid grids, Impact fabric grids are extremely light weight and fold flat for transport in the included carry case.Construction: Synthetic fabricShape: OctagonalBeam Spread: 40°Mount: Touch-fastenerDimensions: 84" (213.4 cm)
