Using simple elastic straps instead of a speed ring, this 15 x 15.7" Softbox for 672S, MB832, 50RS, 520LS, 520S, and 1200D LED Panels from GVM softens the light quality of the bright LEDs, yielding lower contrast and open shadows. The softbox has a reflective silver interior to maximize output, and the front diffuser can be removed to offer contrast options. An optional fabric grid is included for directional control.
