This is the Profoto Acute/D4 flash head. It is compatible with Acute2, AcuteB, AcuteB2 and D4 Generators. It features a circular, quartz flash tube which surrounds the modeling lamp. It provides even illumination and maximum light output. It accepts the complete Profoto system of modular light shaping tools.The Acute/D4 head includes a Zoom Reflector, which slides and locks at your chosen position along the head's chassis. This enables you to control the spread of the light emitted. The Zoom Reflector has a front lip, which accepts honeycomb grids without the need for a spearate adapter.
The included 4m head cable features Profoto special connectors for safety, security and convenience. Unique Profoto cable pin design allows hot-plugging. Change heads without powering down your generator. All heads feature a 5/8" standard stand adapter.
Despite it's impressive power and performance, the Acute/D4 head is one of the smallest and lightest professional flash heads.
Although this head includes a frosted, UV corrected glass dome, other glass covers can be purchased separately to warm or cool and soften or sharpen the light to your personal style.
The quality of the modeling light is almost identical to the flash light, what you see is what you get.
The head has a thermostatically controlled fan for efficient cooling.
Shape your own light
Profoto has designed the heads in such a way that the reflectors can 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 Light Shaping Tools and accessories.
Due to a redesigned glass cover design and improved mounting plate used under the flash tube/model lamp, the light is more color stable, the light distribution more even and the light output is increased.
