For even tougher demands, there is the Profoto Acute/D4 head, that, using two flash tubes, effectively doubles the performance of the Acute/D4 head. 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.

Much like the ProTwin, the Profoto Acute/D4 Twin doubles the performance of a normal head, resulting in either shorter flash duration when used with a single generator or faster recycling/higher power, when used with two generators. The Acute/D4 Twin can produce flashes up to 9600 Ws with two Profoto D4 4800 and up to 1200 Ws when used with two AcuteB 600 generators.

Shape your own light
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. You have access to over 120 different Profoto Light Shaping Tools and accessories.
