Compatible with the B1X, B1, B2, B10, D1, and D2 flash heads, the OCF Magnum Reflector from Profoto allows you to adjust the beam angle of these lights from 40 to 80 degrees by moving the reflector back and forth along the body of the light. Great for long-throw use, the highly reflective modifier will boost the output 1.8 stops. The OCF Magnum Reflector comes with its own protective bag.
