Acute/D4 Twin
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 1200 Ws, when
used with two AcuteB 600 generators (and up to 9600 Ws with two Profoto
D4 4800). The Acute/D4 Twin head also has a fan-cooled head.
The Acute/D4 Twin includes: Magnum Reflector, two flash tubes, 500 W
halogen lamp, removable frosted glass cover, protective transportation cap,
stand adapter and a split 4 m (13 ft) lamp cable.

Acute/D4 Head
With a modeling light of 250 W or 500 W and a maximum
flash output of 4800 Ws, the Acute/D4 Head is the top of
the line of all lamp head for all Acute generators, as well as
the Profoto D4, especially with its fan-cooled head. When
using this head on the AcuteB 600 there is a special adapter
allowing you to use the modeling light with the battery-
powered 65 W high efficiency lamp.
The Acute/D4 Head includes: Zoom Reflector, flash tube,
250 W halogen lamp, removable frosted glass cover,
protective transportation cap, and a 4 m (13 ft) lamp cable.

Acute/D4 Ringflash
The Acute/D4 Ring is a powerful ringflash capable of producing,
for example, 16 flashes at 600 Ws or 64 flashes at 150 Ws per
minute. Fits most cameras and lenses up to a diameter of 100
mm. In combination with the handy AcuteB generator, this
ringflash is the perfect solution for shootings on location.
The Acute/D4 Ringflash includes: circular flash tube, glass
cover, camera adapter, stand adapter and a 4 m (13 ft) lamp
cable. Accessories (not included): Close-up Reflector, Softlight
Reflector, Widesoft Reflector and ProRing Diffuser.
Light spread angle: 70°
Guide number (At 2 meters/2400 Ws/ISO 100/21°): f/45.0
