This is a modifier for use with the Aputure 600d, 600x or 60x.

The Barndoors, Grid, and Gel Holder for the Aputure light storm series are light modifiers that fit the reflector that comes with the light.

The 4-way barndoor design allows for one to four of the leaves to be swung into the light's beam to illuminate areas that you want while keeping light from areas where you don't want it.

The 30-degree grid narrows the beam spread.

The barndoors also include a magnetic gel holder that allows filmmakers to easily add colour to their lights' output.
