A New Bare Bulb Flash Arrives

I invented the term "Faux HSS" to describe "voltage control long flash duration at shutter speeds beyond max sync". It is short and sweet and you do not get sued for using a registered trade name by Pocket Wizard.

Works for me.
It's somewhat amusing to see all the terms that companies are coming up with the "productize" the capability with their lights. Elinchrom has even introduced a special head to length the T.1 time to get better "performance".

HSS, with big strobes, is the new old game in town and every body wants to play.

For sure.
And it appears that Godox has found the best way to do that with 600Ws TTL battery powered option.

They're definitely on a good run and finding their stride.

Even those of us who don't need the TTL version can be very, very happy with the non-TTL strobe as it still has HSS-like capability.

That is exactly why I am against those labels because without a trigger that can sent a pre-sync it is worthless.

But the Godox is bundled with a capable trigger (unlike the Rovelight and older Godox kit).

I'm not sure I follow.

What labels? And Godox makes a decent effective trigger.

HSS.

Godox did not bundle any trigger with the AD180/AD360. If you were satisfied with x-sync you could use the TX-16 trigger. If you wanted to use pre-sync you should be well informed to choose the correct Cells version which would work with your camera.

Edit:

So I am now behind a real keyboard so I can be more specific. To me you have see the triggering system and flash completely separate.

First a look at the camera and triggering moment. I basing this on the a camera with a curtain system as shutter which exist of an first curtain and a second curtain. Normally the curtains meet in the middle of the window but this curtain goes from onside to the other side of the window and also the second curtain goes all the way. The first curtain can unveil the whole window without any movement of the second curtain and the second curtain can cover up the window without movement of the first curtain.

To trigger the external light source can be done on different events of the movement of the curtains.

x-sync is when the first curtain is totally open and is unveiling the whole window and the second curtain has not started yet to move.
second curtain sync is when the whole window is unveiled and the second curtain is starting to move.
pre-sync is when the first curtain has started to move and the second curtain is already following the first curtain before the first curtain has reached the other side of the window.

Now for the light source. It just comes in two settings and that is one flash or several rapid flashes behind each other.

x-sync and second curtain are the easiest ones, the window is not covered by either curtains when the flash triggers. You can use one flash or pulsed light but the first one is the most energy efficient in this situation.

pre-sync is a bit more difficult because you want to emit enough light right at the start of the movement of the first curtain.
If the single flash is long enough to give of light, that you can see all the time the through the slit between the two moving curtains I call it a long burn flash
You can also use pulsed light to do the same, however it will limit the amount of flashes you can produce subsequently and the light intensity is lower due to the pulses.

As mentioned, you want the flash to emit enough light at the start of the movement of the first curtain up to the halting of the second curtain. Different firms has optimized the timings by generating a table including every specific camera that they tested and flash device. This is called HyperSync or SuperSync and you need a camera and flash that is present in the table stored in the triggering unit.
Why is using a table so efficient. That is because you you have big windows (full frame sensor) and smaller windows (cropped sensor). A smaller window needs less time to be covered or unveiled by the curtains so you can use shorter flash durations and so saving energie spend on the flash duration.

Obvious pre-sync triggers comes with a table inside that is specific for brand of camera (Canon, Nikon, Sony, etc.) which are also using different physical connectors (hotshoe) to optimize the pre-sync to size of the window (sensor size).

In total you have now three events on which the flash can be triggered and when you are optimizing the triggering timing you are using a table that is specific for camera and flash.
There are two types of flashes and that is one flash or several flashes behind each other.

Just as on camera shutters and flashes there are different types of them but in general you can use my view to use them to know what is happening and you can then differentiate later on it when you have that specific version of them or you can rely on the table present in the trigger.

The light is HSS capable, some triggers aren't, they are different systems. There isn't anything misleading about the labeling of the units. I can use a very inexpensive trigger and pc sync cable (under $50 usd), and access the HSS functionality of the light. The triggers are a different system.

If you make the assumption that when you buy a kit that includes triggers, that the triggers are HSS capable, then that is a false assumption without researching the triggers. Whatever triggering device you use, wired or wireless, has to be HSS capable, that is pretty common knowledge, isn't it?

I see nothing misleading in these descriptions.

Those that think the kits that are sold together offer HSS out of the package most likely didn't do their research. I know very little about flash, and picked up 2 of these units, but knew exactly what I needed before the purchase, and knew the triggers I was receiving with the bundle wouldn't be all that useful. Being as ignorant as I am about lighting, if I wasn't fooled, then I am unsure how anyone else could be.

Without HSS the flash can still be used up to a shutter time of 8000/sec or higher if you use a pre-sync trigger and set it to full power. It is not misleading, but it does not mention the complete capabilities of the flash.

Thanks for the elaboration and clarification. I know it's challenging in a group of so many to explain in detail so we're all at least on the same page of discussion.

Is the AD600 IGBT? I thought IGBT couldn't be done past 500 Ws...a limitation of the technology and why there's no 1000 Ws Profoto B1. Is the AD600 IGBT and actually 600Ws?

Holy hell, you can combine two into one "remote" head for 1200Ws, and it has an AC pack coming. Wth. Can it really do 1200 Ws at HSS?

The first IGBT monolight I knew about is the Paul C Buff Einstein. it is a 640Ws strobe. The IGBT circuit has to be in series with the tube and capacitor which apparently does create a practical limit.

The AD600 is an IGBT strobe.
