This Airbox Fabric Diffusion Panel from ALZO fits under the front sleeve of all Airbox diffusers to increase the dispersion of light. This 17 x 20" edge-hemmed fabric diffusion panel uses color-coded edges to indicate the 17 and 20" dimensions. It reduces light intensity by a 3/4 f-stop.
This fabric diffusion panel can also be used with most LED lights with barndoors, as it is easy to attach the diffusion fabric to barndoors with metal paper clips.
