The Dedolight 12" (30.5 cm) Translucent Diffuser is meant to soften the light from an available source or from a Dedolight. While in a pinch it might provide slight, soft bounce light, its real worth is exhibited when used with the optional Dedoflex holder (DERH) which affixes directly to a Dedo head and positions the translucent disc in front of the light beam via a flexible arm.
The diffuser folds down to 1/3 its open size and stows in its provided case.
