The Profoto B10 is the smallest and lightest off-camera flash in the range. It has five times the power of a speedlight all packed into the size of a camera lens. You can even shoot video with the integrated continuous light. The Profoto B10 truly is a big light in a small package. The B10 comes as a 250Ws version and is available in two different kits: the B10 with a single head and the B10 Duo Kit with two heads.
