SF600 High Speed Studio Flash Head FLA014


This revolutionary new flash head uses IGBT technology to produce incredibly short flash durations that can freeze even really fast action such as jumping, dancing, hair, martial arts and even bursting balloons!

Insulated-Gate Bipolar Transistor technology works in the same way with this new flash head as with hotshoe flashes, which means that the flash duration becomes progressively shorter when the power is reduced, this is the opposite of what happens with conventional flash heads. At full power, the SF600 produces 600Ws of flash power and behaves exactly like a conventional flash head, with a respectable t.1 flash duration of just 0.8 second, this reduces to an incredible 1/20,000th second at minimum power, again this is at t.1.

And, as the power is reduced, the recycling times become progressively shorter, and even the fastest cameras can't keep up with it at low power settings!

This is the perfect solution for all studio photographers who, up until now, have been forced to use hotshoe flashguns, with their power and accessory limitations, and the lack of a modelling lamp, whenever they have needed to freeze subject movement.

And our optional Wavesync Commander System set allows full remote control of all functions, in addition to triggering the flash head. To get the maximum benefits from the set, it is advisable to have a separate receiver for each additional flash head.

This 600 Ws is by far the most powerful flash head of its type, and it's performance on lower power settings is virtually identical to that of the 300Ws model.

  • 7.4 stops of power adjustment.  A full 7.4 stops of adjustment opens the creative possibilities and allows larger apertures to be used when needed
  • S1/S2 slave options, the slave cell can be set to either respond to or to ignore the first flash, allowing it to be used with hotshoe flashguns that fire a pre-flash. The slave cell can also be switched off, so that it doesn't flash in response to other people's flashes.
  • Full remote control via USB port. This allows you to set the controls on the SuperFast using our Wavesync Commander. as well as on the flash head
  • Uses the same remote control as our other new technology flashes. This means that you can use the SuperFast in conjunction with our other new technology flashes (ElitePro 2, Atom, SmartFlash 2 and future models) and control all of them individually from the transmitter fitted to your camera hotshoe.
  • Fan cooled, to avoid the risk of overheating. It also has overheat protection, for extra safety.
  • Precise digital control of power, displayed on the display panel. The digital control knob adjusts the power setting and displays it on the control panel.
  • 250W Halostar modelling lamp, fully adjustable by separate control, and fitted with a safety cover.

Here are the flash duration test results, published in Advanced Photographer.
There is a disparity between the times we state, and the times stated by the various independent testers. The reason for this is that there is no accurate, scientific method of testing flash durations as short as these!
The standard testing method involves testing the flash pulse with an oscilloscope, and this method is valid for 'normal' flash heads, but oscilloscopes seem to struggle when the flash durations are incredibly short.

Advanced Photographer (and many other testers) uses a spinning disk as the test method, and simply takes a series of photographs using a high-performance camera without flash, these shots are taken at various shutter speeds and provide a benchmark, showing the action freezing potential at any tested shutter speed. The shots are then re-taken, this time using the flash unit under test, and the results can then be compared.
It's a pretty good testing method, because shots taken at, say, a shutter speed of 1/10.000th second produce a very similar result as a flash with a t.1 time of 1/10,000th second.
The problem though, is that although this is a very useful and meaningful test, it isn't scientific - a visual comparison needs to be made, and an estimate arrived at.

The first 4 photos (above) show the action being frozen (or not) by using various shutter speeds on a camera, using ambient light. The other photos shows the same subject, with the SuperFast flash head being used at normal shutter speeds. Professional DSLR cameras tend to have a maximum shutter speed of 1/8000th second, which is nowhere near fast enough for comparing their action freezing potential to the SuperFast.
The focal plane shutters fitted to DSLR cameras inevitably create a distorted image of a spinning disk, due to the movement of the disk as the camera shutter moves across the sensor, and this makes estimation difficult.
The camera used in these tests was a Nikon V1, which has a very fast electronic shutter, producing a shutter speed of 1/16,000th second.
You will see that the distortion here is even worse, making an accurate comparison between the freezing effect of a camera shutter and the freezing
effect of a flash even more difficult to compare, but it's the best method available.

This distortion does not occur when taking photos using the SuperFast.

Flash head
Recycling speed 0.9 second at full power 1/20th second at minimum power At intermediate power settings, each power reduction of 1 stop = a halving of recycling speed, e.g. half power = 0.4 sec, quarter power = 0.2 sec

Maximum power 600Ws

Colour temperature at minimum power 5440K

Flash duration at maximum power, t.1 1/800th at full power. This equates to the action stopping potential of using a shutter speed outdoors of 1/800th second. The figure used by most sellers is based on a t.5 time, which produces a much higher figture but which is far less meaningful
Colour temperature consistency Variation between flashes is too small to measure except at minimum power. At minimum power, the variation is less than 100K
Flash duration at minimum power, t.1 1/20,000th at minimum power This equates to the action stopping potential of using a shutter speed outdoors of 1/20,000th second. The figure used by most sellers is based on a t.5 time, which produces a much higher figture but which is far less meaningful
