This Flag Panel Diffusor is for use with the Dorr LED Flexible Light Panel FX-4555 DL and BC. This metal flag panel frame is ideal for filming - easy to attach. Simply attach the Flex Panel to the flag panel using the elastic straps and mount the flag panel (e.g. onto a camera slider). The flag panel also comes with a fabric cover so it can be used as a diffusor for the light panel.
