ProfotoOCF Magnum Reflector;

Recommended for use with B1X and B1 OCF flashes and D1 and D2 flash heads, the OCF Magnum Reflector from Profoto allows you 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 actually boosts the output 1.8 stops. The OCF Magnum Reflector ships with its own protective case.
