The quadra killer AKA Cheetahstand CL-600

That spec sheet is slick. Good to see it is LiFePO4 battery.

What does 600 W/S (True 500 W/S) mean?

Also, I think there is a typo on the Power Adjusting line. I think 1/32 to 1/1 is 5 stops and not 16. Is it supposed to be 16 steps instead of stops?

Thanks for taking the chance and previewing the unit.

Godox rates it as 600ws and Cheetahstand rates its above 500ws and rounded it down like the cl-360

Its suppose to be steps

This light uses voltage controlled power adjustment. The spec sheet shows that flash duration increases a power is reduced. That is a characteristic of voltage controlled power adjustment. What Scott is doing is using Hyper Sync, Super Sync or whatever someone whats to call it which is using the flat tail of the power curve to illuminate the subject while the shutter curtains move across the sensor.

The CL bare bulb strobes use H mode which is the rapid pulsing to create a long flat power curve for the duration of the shutter slit travel. Two completely different approaches. Similar result.

H mode and Hyper Sync both are relying on the shutter speed to stop action since they are both constant light sources for the duration of the shutter travel and would do a poor job of stopping action.

Thanks for explaining that David

Yes I understand completely. These strobes for action sports or dance would be most useful in HSS and less useful in low ambient light due to decreasing flash duration as power is decreased. It looks like the Cl-360 might be a better choice for stopping action at normal sync speeds. The only reason I mentioned Einstein is because I have used them for this purpose and they worked well due to the short flash duration. I was not looking to start a war just gather useful info on the new strobe.

Hmmm, 1/32 minimum power doesn't give you much range for indoors, considering CL-360 does 1/128 and Einstein does 1/256.

What is the flash duration at the different power settings? Any action stopping capability with these strobes?

Flash duration at full power, t.5. 1/4500th sec
Flash duration at half power, t.5 1/3200th sec
Flash duration at quarter power, t.5 1/2700th sec
Flash duration at eigth power, t.5 1/3000th sec
Flash duration at sixteenth power, t.5 1/2550th sec
Flash duration at thirtysecond power, t.5 1/1800th sec

Flash duration at full power, t.1. 1/1500th sec
Flash duration at half power, t.1 1/1000th sec
Flash duration at quarter power, t.1 1/900th sec
Flash duration at eigth power, t.1 1/1000th sec
Flash duration at sixteenth power, t.1 850 th sec
Flash duration at thirtysecond power, t.1 1/600th sec

Well most people that buy a battery system is going to use it out on location. I get f/5.6 at 8 feet with a stock reflector ISO 100 once you put on a modifier your going to drop that 5.6 to 2.8 how much lower do you need to go?

I wrote in the 360 bare bulb thread that the 600 is good to 1/32 and if you need something less then that then the v850,v860,180,or the 360. If you bought the 600 and a v850 it would still be below the cost of the Einstein and Vagabond and you can use one as a main and one as a fill. I can buy 600, 360 and 2 v850 for the cost of one head quadra kit.

Again its up to you what you want to buy and use. For those that can't afford a Elinchrom Quadra system and want something that performs better then the cl-600 is worth getting.

I have a UK version, badged as Lencarta, they claim to have a custom spec from the factory too

Does anyone know whether the triggers for all these systems which took identical are totally compatible?

It never occurred to me that hyper sync would work so well with it, I'll give it a run out next week.

There is no custom specs between the Lencarta or the Cheetahstand. Edward just had them change out the hardware like the tilt handle, spigot locking nut, and the cable.

They are all manufactured by godox and you will need the cells II or a yn-622 to trigger HSS on the camera

But not in the USA as far as I can see from that website.

So does the Lencarta flash duration chart apply to the Cheetah strobe? I did not know they were the same.

I don't have an oscilloscope and can't answer that question. Their other specs are pretty close, so may be.

Yes the Cheetah version seem to have the older model's flash duration of 1/800 to 1/2000 sec. It looks like only the flash head is of a new design.

Cheetahstand and Lencarta are the exact same head and packs. They do not have anything special or proprietary between the two units. The only difference between the companies units are the cosmetics. Some companies want to fug the spec to make a unit look better.

For example if you look at all the places on the net that sells the ad-360 some will say its 400ws, 360ws,and 300ws. They are all the same units from the same company, but the true Ws is closer to 300. A lot of place round up to make their units look more attractive, when they should be round down or showing exact output.

I don't have the all the tools to give mathematic equation or would I want too. I have better things to do with my time, like actually shooting and seeing what it can do.

Since Jan of this year I spend well over a few thousand dollars on cheetahstand gear. I'm happy with my purchases and feel I should share my thoughts. Edward is always a hoot to talk too and if I don't like a item I him and others my thoughts about it.

Scott,
I remember that the quadra had an 20 or 30 sec operating cycle before the light would go out. Does the 600 have any limitations on the use of the modeling light?

What seems to be confusing this discussion is that several retailers, in different countries, are buying the Godox hardware and rebadging it. As Scott points out. A specific retailer can request certain changes for their own purposes, but they do not extend to the core product since that would require significant retooling of an assembly line. Case changes, bracket changes are easy to accommodate. Changing the circuitry to alter the flash duration would change the core design.

It is also important to remember that HSS (High Speed Sync) is a specific technology implemented by camera manufacturers to make their speedlites capable of supporting FP sync so that shutter speeds greater than X sync can be used with the speedlites.

HyperSync, SuperSync or whatever trademarked terms are used, refer to a hack that makes the camera think that it should switch to FP Sync so that the strobe is fired early. This permits the slowing diminishing tail of a voltage controlled strobe to illuminate the subject while the shutter slit travels across the sensor.

They are not the same technology and not synonymous terms.

H mode, as implemented in the Cheetah/Godox bare bulb strobes is similar to HSS in that is uses the same rapid pulsing to elongate flash duration over the period required for shutter travel. Its not HSS because there is no metering via the camera ETTL system.

The Cheetah 600 sounds like a great light. But, it is different technology than the CL-180/360 regarding power control circuitry and thus flash duration. The good news it that they are speccing the t.1 time which will help those wanting to use HyperSync hack.

The Quadra can be set from 1s to 60s or you can hold the button down for 3s and it will stay on till you turn it off. The 600 will stay on till you turn it off.
