For even tougher demands, there is the Profoto ProTwin, that, using two flash tubes, effectively doubles the performance of the ProHead. When used with a single generator, it produces shorter flash duration. Used with two generators, it achieves faster recycling and/or higher power, up to 9600 Ws.
Profoto has designed the heads in such a way that the reflectors are possible to slide back and forth on the head allowing you to zoom on and out or to "paint" with the light.
