This is an Honeycomb 3-Grid Set with 7" Reflector. It includes a 12, 20, and 30° grid and a gel filter holder.
Grids are essential accessories for any lighting system. These devices alter the shape and intensity of the light output from your flash heads. Use of a grid will result in a small circle of light when it is attached to the front of your light source. The size of the circle of light will be determined by the density of the honeycomb, its thickness, and the distance of the subject.
