The Elinchrom Rotagrid Front Diffuser Mk II is a replacement front diffuser for the Elinchrom Rotalux 90x110cm Rectabox Softbox (26176 or 26641). It features a handy Velcro located on the outer black frame which helps hold the Rotagrid in place. This is great when using the grid on a bigger Rotalux; making it more secure on the Softbox in case an external diffuser is required for further diffusion. The Rotalux softboxes themselves offer double diffusion delivering super-soft lighting. For a more dramatic look, use the Rotagrids with the inner diffuser; alternatively use with new Mk II front diffusers for additional softness.
