Elinchrom Hooded Diffuser for the Rotalux 27" Square Soft Box #26178.

Rotalux Hooded Diffusers - Like barn doors, the edges of the hooded diffusers are terrific for preventing light spill and allow the light to be feathered better than softboxes without an edge. To ensure optimal optics and a tight fit, Rotalux hooded diffusers are assembled during the rod insertion process and therefore remain secured to the softbox when it is closed.
