This is a 10° honeycomb grid for the Profoto Wide Zoom reflector. Grids are essential accessories for any lighting system. A grid modifies the shape and intensity of the light emitted by your softbox when mounted on a lighting head. Consider a grid as a painter would consider a brush, or a sculptor a knife or chisel. Honeycomb grids and "eggcrates" are rigid or semi-rigid. Fabric grids are hand-sewn and fold easily for storage or transport. Using a fabric grid, honeycomb grid or "eggcrate" will produce a narrower light spread. The light spread will be determined by the density of the honeycomb mesh and the distance from the subject to the light source. Unless otherwise stated, a grid mounted on a softbox will limit the light spread to 40° from the face of the softbox.
