Technical data

The new Profoto D4 is fully compatible with the existing line
of Acute Heads and the new ProHead. Furthermore, all former
Acute and, in 220-240V countries, Pro-3-5-6-7 heads can
be used. This allows full interchangeability between the
generators and the entire line of Profoto light shaping tools,
ensuring the very finest quality of light possible every time
an exposure is made.
The legendary design of Profoto heads permits accessories
to be “focused”. By sliding the reflector back and forth on
the head, the angle of light as well as the quality of the light
changes. In the narrowest position, light produced is hot
in the center graduating off towards the ends, making
dramatic lighting easy, even when using a large soft box.
In the widest position, light is even from the center to the
edges illuminating the area evenly. This flexibility is rarely
seen in lighting systems, but it is the basis on which all
Profoto light shapers and heads are designed. The Standard
Zoom Reflector is a universal tool. It offers the functions of a
wide angle, umbrella and standard reflector.
The heads feature circular, heavy-duty, Quartz, ozone-free
flash tubes with frosted protection domes that surround
both the flash tube and standard 250 watt (500W option-
ally) halogen modeling light. They provide matched and even
illumination with maximum light output efficiency. As with
all Profoto lamp heads, special ”arc-proof” connectors
provide safety while ensuring maximum performance and
ultimate reliability. All heads are supplied with a 5/8-inch
adapter to mount the units to any standard light stand.

Similar to the Profoto AcuteHead, the TwinHead offers many
of the same features.The main difference is the use of two
U-shaped flash tubes. The use of two separate flash tubes
allows twice the amount of energy to be released from a single
head. The two separate power cables can be connected to
two different generators allowing up to 9600 watt seconds
of energy to be released through a single light shaping tool,
or you can get shorter recycling time.If both cables are plugged
into the same generator, shorter flash durations are achieved.
Unit includes: two quartz flash tubes, 500W halogen modeling
lamp, 5m (16.4’) lamp head cable, removable, frosted glass
cover, Magnum Reflector and plastic transportation cap.
Umbrellas can be mounted directly in the head.

Modular heads feature fan cooled operation and accept all
Profoto light shaping tools. These heads feature heavy-duty
cables to allow for higher performance and greater reliability.
The 250 watt (500Woptionally) modeling light features a
mini-can base, which is standard in professional lighting
systems. Also included: quartz flash tube, frosted glass cover,
5m (16.4’) lamp head cable, Standard Zoom Reflector and
plastic transportation cap. Umbrellas can be mounted
directly in the head.

Popular with fashion photographers for its direct and detailed
light, the ringflash also has many applications in commercial
photography. The even wrapping of light produced by this
200mm Ø ringflash offers a unique subtlety not found in any
other light shaping tool. The adjustable tripod mounting
bracket permits it to be used with almost any camera and
lens combination.
