Attaches securely to V- and Tota-lights, providing more control of the light. With the pivoting Tota-shade, you can shape the beam, shade overly bright areas, and cut spill and lens flare. Tota-shades can be attached to each other to make a larger barndoor. You can attach 4 to one light for a conventional barndoor system. (If side panels are desired, top and bottom panels are required for support).
