Softgrid 30 for Softbox 1x 3' Shape the light with precision. All HR softboxes have a recessed front that means that you can attach a Softgrid. The Softgrid reduces the light spread to either 30° or 40° depending on which Softgrid you use. In other words, the Softgrid creates a more directed light & eliminates a large amount of spill light, allowing you to shape the light with even more precision.
