Use this Chimera Fabric Grid on the front of a 54 x 72" Chimera Large, or Photoflex Extra Large softbox to limit the light spread to 30°.
Grids are essential accessories for any lighting system. A grid alters the shape and intensity of the light output from your softbox when it is mounted on a light head. Consider a grid as a painter would a brush, or a sculptor would a knife, or chisel.
Fabric grids are hand-stitched, and collapse easily for storage or transport. Use of a fabric grid, honeycomb grid, or "egg crate" will result in a narrower spread of light. The spread of light will be determined by the density of the honeycomb mesh, and the distance of the subject from the light.
