The MDF-1 Milk Diffuser Filter Frame is a Milk Diffuser for 1x1 Panel Lights with metal frame which you can attach barn doors (sold separately). The frame snaps into the new quick release mounting system found on the K4000 SE and the K4000 Power.
Note: The MDF-1 is only compatible with lights that use the new push-button corner mounts. If your light has the old style of mounting corners please contact us on how to upgrade your light to enable you to use the full range of grids and barn doors.
