The Profoto 20 OCF II Grid is made for the B10, B10 Plus, and B1X. It narrows the fixture’s approximately 77 beam spread for selective lighting. It is simple to stack OCF II gels on top of the grid, which is magnetically attached to the OCF II Barndoor or the OCF II Grid and Gel Holder. The light’s beam spread is significantly reduced by this 20 grid. Additionally, there are grids with a 30 width and a 10 width.
