Profoto 900618 Acute2/D4 Black Flash Head

The Profoto 900618 Acute2/D4 Head is a professional-grade flash head designed for demanding studio photography work. Built to pair with Profoto's Acute2 and D4 power packs, it can channel up to 4800 watt-seconds of flash energy, providing the output needed for large-set commercial shoots, fashion photography, and high-volume product work. The heavy-duty plug-in quartz flash tube is engineered for longevity under repeated high-power use and can be swapped out quickly when a replacement is needed, minimizing downtime during sessions.

A UV-coated frosted glass protection dome ensures consistent color temperature at a standard 5400°K, while the 250W modeling lamp lets photographers visualize lighting patterns and shadow placement before committing to a shot. The head features a removable, adjustable zoom reflector for quick beam-width control, and its 5/8-inch stand adapter mounts securely to standard light stands. Critically, the Acute2/D4 Head accepts the full range of Profoto modular light shaping tools—softboxes, umbrellas, beauty dishes, snoots, and grids—giving photographers extensive creative control over their lighting without switching systems.
