The Profoto Acute 2-D4 modular flash head design features a circular, heavy duty, quartz flash tube and UV coated protection dome that surrounds both the flash tube and the 250W modeling light. It provides even, consistent illumination. All lamp head cables feature Profoto special connectors for arc-proof performance. All Acute 2-D4, 2, and Acute heads accept the same modular light shaping tools.
The flash tube in this head can handle up to 4800 w/s, when used with a D4 series power pack. The modeling lights for this unit are readily available in a variety of voltages for use all over the world.
