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.

This Acute 2-D4 Head produces a color temperature of 5400°K as supplied. There are other optional domes that are more heavily coated, for a warming effect of 300 or 600° increments, for a color temperature of 5100 or 4800°, respectively. A power supply for this flash head is required.
