The Nanlite Stripbank Softbox with Bowens Mount (12x55in) dramatically softens the output of a light source with a high degree of directional control thanks to its long narrow form factor. Control and Shape Light Designed to illuminate a "strip" of the subject with limited light spill, this softbox is well-suited for side-lighting in portraiture, accenting cars and bikes and photographing glassware and other reflective objects. Bowens Style Speed Ring Created to be compatible with Nanlite's Forza Series LEDs, the Stripbank Softbox includes a Bowens Style Speed Ring. This near-universal light modifier mount expands compatibility to an extensive range of LED, strobe, and constant light sources. Accepts Optional Fabric Grids For additional control of light spill and added directionality, an optional fabric grid can be mounted via touch-fasteners. The fabric grid narrows the beam angle to 50 degrees and concentrates the light's beam forward. Fabric Grid sold separately, SKU# EC-140X30
