CONONMARK – i6T EX Leopard – Wireless TTL, HSS, 2.4GHz, Strobe Announced

CononMK i6T EX


Portable strobe light manufacturer Cononmark have announced a new 600Ws all in one wireless version of the TTL and HSS enabled Leopard series of Lithium-ion powered strobes.

The i6T EX Leopard providing 2.4GHz, auto detect / switching, Canon, Nikon, and Sony TTL and HSS compatibility in the one strobe. UPDATE – Fuji and Pentax have also been added.

Recycle time is also lighting fast at one second on full power (in Quick Mode).

UPDATE – The i6T EX Leopard are now available from B&H Photo under their “Impact” house brand, as the Venture 600-TTL.


CononMK i6T EX


In power saving mode (which increases recycle time to around 3 seconds) 400 full power flashes can be achieved from one charge of the compact 14.8 Volt 2000mAh Li-ion Battery.

And the compact i6T EX strobe weighs just 2.1kg with battery pack installed (2.26kg with Bowens accessory mount attached).


CononMK i6T EX


The 2.4GHz Cononmark ABC transmitter units are available for Canon, Nikon, Sony, Fuji, and Pentax, TTL and HSS systems (in both Minolta style and Sony Multi Interface shoe options).

The ABC transmitter provides fast adjustment of 3 separate flash groups, and allows mixed TTL and remote manual groups to be used at the same time. (With Canon this works with pre 2012 cameras as well as post 2012 models).

Second Curtain Sync is also supported.

Remote manual power control is supported with Fuji, Pentax, and single firing pin cameras.



The i6T EX’s 15w LED modeling lamp has 4 operating modes available and can be switched on and off and adjusted remotely (from 10% to 100%) from the ABC Transmitter (or directly on the strobe).

Or set to adjust automatically with the strobes power level.

    Someone finally supported Sony version. Kudos!

      Hi Ken,

      As far as I’m aware CononMk where first with Sony support in a TTL strobe like this, and the K4T leopard have been available for close to a year now. The K4T are nice strobes as well, you don’t realise until you actually see one how small they actually are (for a 500Ws strobe).

      The cool thing about both of these flashes is you can literally shoot with a Canon, Nikon, and Sony camera at the same time in TTL or HSS. The strobe automatically recognises which cameras is trying to take the picture as needed.

      • JL Williams 4 years ago

        But you still need a Nikon-, Canon-, or Sony-specific transmitter, right? So all they’re really saying is that the same flash works with all their transmitters.

        • Author
          Flash Havoc 4 years ago

          Hi JL,

          Yes if you want TTL and HSS features, then you need a dedicated transmitter for each camera.

          I guess it could be possible to combine at least Canon and Nikon into one transmitter with multiple contacts on the foot. I fear they would tend to be a bit less reliable though, and these transmitters are fairly inexpensive anyway.

          The main advantage though is you can literally have a Canon flash on one shoulder, and a Sony A7 etc on the other, and pic up either camera and just shoot as needed. Or have a second person using a different camera to you while sharing the same lights.

          In comparison most strobes with radio receiver support for multiple brands require you to choose just one receiver mode at a time.

          • Marco 4 years ago

            A good news for fuji and pentax users.
            I contected cononmk and a fuji and a pentax tx, supporting ttl and hss will come later. Hope others manufacturers will follow (godox are you listening?)
            This seem a really interesting producs, but reading your comments it seem the real power it’s more like 300ws, so the godox ad360ii still seem an interesting options, lighter and smaller (but it needs an adapter to use bowens accessory and tripod mount)

            • Ulysses 4 years ago

              Marco, thank you for reporting on this. But which strobe did you connect to a Fuji? Was it the i6T EX strobe? And which Fuji and Pentax body were you using?

              • Marco 4 years ago

                They are developing an ABC ttl/hss trasmitter for pentax and fujifilm X series to use with i6T atrobe (and i hope k4t too)
                That’s a great news in my opionion

                This is the cononmk answer
                “1. so it will be possible to use hss on a pentax 645z ou with a fuji x mirrorless camera?
                YES, it wil be.

                2. You will release a differemt transmitter for each brand ot it will be an “universal” tx?
                Different brand with different transmitter.

                3. Any idea about of release date?
                About the release time for Pentax and Fuji version, we cannot give you a definite time now. We need get the approval of our supporters from Japan side.
                We will release the sony, nikon and canon version in Jan 3rd, 2016 with a product launch. Any updates, I will inform you ASAP.”

                • Ulysses 4 years ago

                  Marco, this is tremendous news, especially for photographers who shoot with mixed brands of cameras. The only thing that might be better is if they had a universal transmitter for manual remote power control.

                  For example, I shoot also with Olympus cameras, as well as Canon and Nikon. I don’t expect a dedicated transmitter for Olympus brand as the market is certainly too small. But a universal remote for power control would help a lot of photographers perhaps even more than making for specifically Fuji or Pentax. Still, it’s nice to see they are forward thinking.

                  • Marco 4 years ago

                    Each trigger it’s of to contro power in remote, with any brand. You need a dedicated trigger for hss/ttl

      • Ulysses 4 years ago

        Elv, this i6T EX is an incredibly compelling strobe. From the sound of things, it’s an obvious competitor to the Godox AD600. Even though CononMK may not yet have the complete system of flashes through 600 Ws strobes that Godox does, they’re offering a really nice feature set here. Plus the ABC transmitter is much improved along with a few tricks up its sleeve.

        Since you have one available for review, can you tell us: If an event photographer needed to have an on-camera flash in addition to controlling the i6T EX, what would be the simplest options? I see the transmitter has no hot shoe for a flash.

        At $1000 the flash is rather on the higher side of costs. And while the ABC transmitter is much improved over the old one, CononMK would do well to come out with a transmitter that offers even more flexibility. I think a lot of Godox shoppers might even switch their attention if CononMK did this (or came out with a flash of their own!).

        • Mark 4 years ago

          Hi U, I agree that this looks good but lacks the range of the Godox lineup. I am re-thinking my need for 600ws though as I recently was able to shoot some large night landscapes with my AD-360s. I DO need it for bright sun fill at range but a couple of nice light weight AD360s would do the same.

        • Author
          Flash Havoc 4 years ago

          Hi Ulysses,

          Yes flash on camera is going to be a problem at this stage if you want TTL with the i6T EX.

          I think manufactures of strobes like this and the Interfit S1 etc are looking to the standard Profoto have set with the B1. I think it is fair to say there is larger segment of the market for strobes like these that do actually need a flash on camera at times though.

          At this stage the best you could hope for is remote manual power control, (and possibly long duration sync at full power) by using alternative radio triggers, or master flash and receiver attached to the i6T EX via sync cord just to fire the flash. Then the ABC transmitter in hand to remotely adjust manual power levels.

          The AD600 or Indra have a considerably advantage for flash on camera users.

  2. Niels Gram 4 years ago

    Very interesting, however a minimum recycle time of 0.2 sec makes it unusable for me. I want my light to be able to match the 10 fps frame rate of my camera.

    • Burek 4 years ago

      @Niels Gram: only continuous lights sources are usable for you

      • Niels Gram 4 years ago

        I shoot outdoor without access to mains power, so continuous light isn’t an option (can’t bring generators with me).

    • Author
      Flash Havoc 4 years ago

      With the 7D at 8 frames per second 1/250th shutter speed I could get (before the flash needed to recycle):

      10 frames at 1/4 power
      21 frames at 1/8th
      1/16 power and anything below would go on continuously.

      • Niels Gram 4 years ago

        Thank’s ! Was this with the i6T EX ? If so, the spec is clearly wrong. 8 FPS mean that the min recycle time is at most 0.125 s Did you check that the light output didn’t decrease while shooting continuasly ?

        • Author
          Flash Havoc 4 years ago

          Yes that was with the i6T EX.

          I just took a closer look and at 1/16 the light output does jump around by up to almost 1/2 a stop in total. Mostly 2 or 3 tenths variation though.

          At 1/132 its very consistent with only a tenth or so variation at most.

          I haven’t really done much testing previously with high frame rates, its possible other strobes may be comparable with this as well.

          • Niels Gram 4 years ago

            Thank’s 🙂 That actually sound quite promissing.
            I tested a few speedlites with external power (Canon 580II, 600EX-RT, Yongnuo 560III and YN600EX-RT). They all provided very stable light output or didn’t fire at all. I also tested the Godox AD180 at 1/16 power. The light output of this flash rapidly decrease by 2/3 stop and remain stable at that level. My guess is that the AD360 would do the same. The AD360C-II may do better since it’s a TTL flash. It would be interesting to know how stable the output of the AD600 is…

      • Rany 4 years ago

        Hi, I frequently shoot marathons.
        At flag off I need to shoot continuously.

        Currently I am using YN560IV wirelessly. Unfortunately it can’t do HSS by itself, at 1/250s it often cannot completely freeze movement.
        Good to know that at 8fps i6T can keep shooting at 1/16 power.

        Has anyone tested how many shots with HSS at 1/16 power at 1 shot per second this flash can do before overheat protection kicks in? Or will it happen? Thank you!

        • Author
          Flash Havoc 4 years ago

          Hi Rany,

          I haven’t tested this, though I can give it a run.

          I think the flash is somewhat similar to the Phottix Indra, which don’t appear to have much of a limitation in HSS. At 1/16th power though I doubt you would have much issue in any case.

          • Rany 4 years ago

            Greatly appreciated. Just need this info to make the decision. I am Sony user so choices are limited.

            • Author
              Flash Havoc 4 years ago

              Ok I just gave this a run, and although the flash kept up until I ran out of buffer at 120 shots on my Sony A7, I don’t think the results are actually very good in HSS mode at this rate with the i6T EX.

              I was shooting a white wall so I could see the light pattern and exposures easily from frame to frame and they are not very consistent at all. I was watching the light meter while shooting and that was only varying a few tenths between shots which is nothing unusual, though the light in the actual images is varying across the frame and different in each frame.

              I gave the Godox AD600B a similar run in comparison (with Canon as I don’t have any Sony HSS transmitter) and its far more consistent at this shooting rate as well as putting out a stop more power which I get the impression you would really need as well.

              If shooting fast continually like this in HSS is priority I think I would scratch the i6T EX from the short list unfortunately.

              The other options for Sony right now would be to use either the Phottix Odin for Sony, or possibly a second hand set of Pixel Kings, and one of the other lights like the Indra 500, AD600B, or even the RoveLight. If your not interested in TTL the RoveLight would likely suit this best.

              The Indra and AD600B will have Sony compatibility coming though, its just a matter of when.

              • Rany 4 years ago

                Thank you for your time.
                Just to confirm you shot at 1 frame per second?
                If that’s the case then looks like I will wait for Godox.

                Thanks again!

                  Hi Rany,

                  Yes, I was only doing it roughly manually with a stop watch, I didn’t set up a remote timer. It was certainly faster than I expected though, and even my 7D I think ran out of buffer.

                  Maybe the effects would not be too noticeable in your particular images, though I’d still say they are the least ideal of the lights for shooting fast in HSS like that.

                  • Rany 4 years ago

                    Thank you. I will wait.
                    I like it to be one piece, without need for extra receiver because I already have plenty to carry, and that I move alot and shoot long hours.

  3. Paul R 4 years ago

    I have a different take on the recycle.

    A 1 second wait for a full 600ws pop?

    That is phenomenal as long as this thing isn’t $3,000.

    That can’t be correct.

    • Author
      Flash Havoc 4 years ago

      Hi Paul,

      It is correct, and I was blown away by the recycle time initially, though there are some catches to it.

      When I compared the power to the RoveLight / Jinbei HD600 II they are at least a stop apart. So setting the RoveLight to half power and the recycle times of both are about equal at the same light output.

      So the i6T EX’s recycle times are not actually anything ground breaking, though the RoveLights are a standout for power and recycle time in a battery strobe as well.

      EDIT / UPDATE – We now understand the power extension mode increased the i6T EX’s power by ones stop, while increasing the recycle time to 3 seconds.

      • Paul R 4 years ago

        LOL, I am so confused.

        I don’t own a Rovelight, but I did watch a great independent review of it on youtube and I have to admit, I thought recycle on fast mode was kind of slow. 3-ish seconds?

        Just for clarification, your tests are showing the i6T-EX (what an awful name) as 1 stop less output at full power as the Rovelights?

        I hope this isn’t an omen of a future where strobe manufacturer’s start lying about the output of their flash units to squeeze in features we want like high quality reliable radio transmitters, TTL, HSS and overall light weight and portable units.

        • Ulysses 4 years ago

          The recycle time of 1 to 3 seconds — a full 600 Ws (or 500 or so more likely) — in this category is pretty impressive. Most times you won’t need to use full power, and so those times drop even more so. Of course, your needs and the experience you have with other lights may vary. If you need something faster and with more power, then chances are that you’re looking for something else entirely.

          It seems that this is generally the way strobes are headed when it comes to measuring their output level, often in this category being slightly under what is advertised. But what would seem to matter even more is whether or not the light fits your need both in features and in coverage. P

          The i6T EX (note no dash in the product name) looks like an interesting offer because of its power, features, and multi-brand compatibility. So here’s hoping it delivers on at least what is advertised, and hopefully more.

  4. Niels Gram 4 years ago

    I didn’t complain about the full power recycle. In fact I think 1 second for a full 600Ws pop is the best available on the market today by a considerable margin ! I just want the recycle time to “scale” with the power of the light output of the flash. That’s normally the case for IGBT type flashes but not for voltage controlled flashes. If the recycle time scaled with the power output by the flash I could use it at e.g. 1/16 power and have it follow the 10 fps. 600Ws at 1/16 power that will be plenty of light for my use !

  5. daemorhedron 4 years ago

    Decisions, decisions. This has almost everything you could possibly hope for, but definitely minor differences between this and the Godox AD600B that makes for a really hard choice! Will be an interesting year in lighting, that’s for sure =)

  6. Niels Gram 4 years ago

    Extra question: Is it possible to use the CononMK trigger as remote control of power and use the sync input to trigger the flash ? I would like to be able to contiue to use my speedlites in conjunction with something more powerful.

          Exciting times ahead! I’m incredibly interested to hear more about this one.

              Sorry I’ve been doing renovations for a while and I’m completely exhausted.

              The AD600B (Bowens mount) should be here in around a week or so as well. And there are a number of TTL strobes being released at the moment as well.

              So I’m going to have to put the tools down for a while concentrate on these strobes. And hopefully try and get to the bottom of how they do actually compare in terms of things like power output, recycle, and particularly color variation etc.

              They will likely be more facts and figures than pretty pictures etc for the moment.

  7. Sam 4 years ago

    Can you manually turn on HSS so you can use it with Olympus In manual mode but HSS (since you can trick the Olympus to send the “early flash signal” through the center hotshoe pin). You can the use a simple radio trigger between camera and flash.

    • Author
      Flash Havoc 4 years ago

      Hi Sam,

      I’m not actually sure as the HSS symbol is always on on the strobe. I don’t think there is any option to turn it on and off on the strobe or transmitter, as the transmitter is meant to engage HSS automatically as needed.

      I’ll have to test this more, though my guess would be you would only be able to do “long duration sync” with the strobe set to full power.

      In other words, I don’t think the strobe is going to pulse unless its receiving the HSS signals from the ABC transmitter (mounted on camera, and set to a shutter speed over x-sync).

  8. Jerome Yeats 4 years ago

    The product photography is “good” but black on black is IMO hopeless for clearly seeing what the flash consists of. There does not appear to be a handle on the flash unit and what the mounting system is goodness only knows. There does not appear to be a long lever to make the head go up and down. I may be missing something.

    Off topic, I’ve just bought a Godox Thinklite 660 II for my own test purposes. I bought it new on ebay and twice the sliding door for the AA cells has opened by itself. At the price i got it for I can’t complain, and while I have two Godox Witstros I will stick to Yongnuo 560s for the moment. Bring back the original 560s say I. I liked those little circular lights at the back of the flashes. Ah well.

    • Niels Gram 4 years ago

      Take a look at the product photos of the k4t. They may answer your questions… as far as I can tell, the new flash is quite similar in many ways:

    • Author
      Flash Havoc 4 years ago

      Hi Jerome,

      The swivel attaches to the base of the strobe with a thumbscrew so that it can be removed. And a plastic handle is supplied to be used in place of the swivel when needed.

      As Niels mentions this is the same system as CononMK’s numerous other strobes use.

      The swivel has teeth in the hinge joint, so it locks into place quite firmly with just the use of a small handle instead of a large lever. CononMK have evolved this compact swivel over time and it works quite well now.

      The mount used is Comet, though CononMK have intentionally designed a Bowens mount adapter which is very shallow.

      So this is more like a Bowens mount flash which has a removable mount. That way its even more compact and lightweight when only attaching a 7″ reflector (or other compact Comet mount modifiers).

      Its really better than just having a Bowens mount, so I can understand why CononMK want to keep going this way. The K4T is incredibly small, so having the smaller mount built in as well makes sense.

    How much does it cost?

    $1,200 or $1,500?

      Flash Havoc 4 years ago

      Hi Jack,

      They are currently CNY 6500 RMB, which is currently approximately $1000 USD, direct from CononMK.

      If local dealers pic them up (and possibly rebrand them as B&H’s Impact brand etc currently does with CononMK lights) the prices could possibly change.

  10. nixland 4 years ago

    So Elv, what are the plus and minus points of this strobe compared to Godox AD600?

    • Author
      Flash Havoc 4 years ago

      Hi Nixland,

      I haven’t had a chance to properly inspect the i6T EX yet. And the AD600B should arrive in a week or so.

      I suspect they will be similar power output, though the AD600 appear to be a bigger strobe with larger battery.

      As mentioned further up Godox have the advantage regarding flash on camera use at the same time. And a larger compatible range of strobes and speedlites etc.

      The i6T EX and K4T have Sony compatibility already, where Godox are still working on that.

      Both of them are going to work on an AC power adapter. The AD600 also have the remote head option. No mention of that for the i6T EX (though they are a little smaller and lighter).

      • nixland 4 years ago

        Thanks a lot Elv.

        About the recycle time, its only 1 second at full power? The AD600 is 2.5 second.
        Can’t wait to see your test result 🙂

        • Ulysses 4 years ago

          Even 2.5 second recycle time isn’t bad for 600 Ws of power. It makes the 1-second time rather remarkable for this category of flash.

          BTW, did you see this video I posted earlier of the i6T EX being fired at full power? It seems just a tad longer than 1 second, but it’s close.

          • Author
            Flash Havoc 4 years ago

            I’m not sure if I explained too clearly earlier, though the RoveLight / Jinbei HD600 II recycle just as fast when set to around the same amount of light output (around 1/2 power on the RoveLight compared to full power on the i6T EX.

            So not only are the RoveLight just as fast at recycling, they pump out twice the light output when needed, in a unit that is only about 400grams heavier. And the includes a larger battery with more pops available.

            So its likely more a case of the 600Ws title being a little optimistic. But that’s likely going to be the case with majority of similar alternatives (like the Godox AD600 etc) as well. So in that sense the i6T EX should have a considerable advantage over those flashes.

            Jinbei are also working on a TTL version of the HD600, though I’m not sure about the expected time frame.

              A TTL Rovelight would be amazing

      • Ulysses 4 years ago

        Sorry to mix comments about the AD600 into this story on the i6T EX. But they’re such close competitors in many ways that it’s difficult to talk about one without mentioning the other.

        The AD600 certainly has my attention because on paper it looks like the natural progression of a complete system — flash, bare bulb 360 Ws super-flash, and now a feature-packed 600 Ws strobe. As a pro photographer who uses strobes and flashes at events, as well as for portraits, it would seem to have it all. But I’m also reading mixed reports about the TT685 flash such as exposure inconsistencies. Even though I already have quite a bit of Godox/Cheetah gear, I’m not yet 100% sold on the AD600.

        Hence my interest in the i6T EX. I’m hearing that their family of strobes are quite capable, color stable, and that the ABC transmitter is reliable. The only thing missing is a compatible flash to complete the system. LOL! Seems no matter where we look, it’s difficult to have our cake and eat it too. 😉

        • Sam 4 years ago

          It seems that the Godox AD-360, despite having “360” in it’s name, has generally been tested by reputable reviewers as being closer to 300 ws.

          So it might be worth everyone of us (myself included) taking a step back from the “label” and either using “approximate ws” or comparing different strobes by citing other attributes or capacities?

          Just a suggestion…..

            That is what guide numbers are for, though unfortunately they are highly subjective and often fudged as well. The only way you really know is to get both lights in the same modifier and compare the results.

            I haven’t had to do it for a while now, though we were tending to use the Phottix Luna collapsible softbox / beauty dish as the standard, because many people have them (or other rebrands of the same modifier) and they are a pretty specific design.

          • Ulysses 4 years ago

            It’s fairly well known what the power output of the Godox/Cheetah super-flash is. In fact, CheetahStand refers to it as “300 true Ws” or some similar phrase. Most people who buy it know the same info. My earlier reference to “360 Ws” was a simple typo, so my apologies on that one. I do usually refer to it as 300 Ws. But the overriding point stands — that Godox has a very broad range of tools in production, making their offerings comparatively deep.

  11. Zia 4 years ago

    The ad 360 godox has a limited 1/ 8 output in hss and 10 pops at full power . Is this strobe limited in hss mode ?

    • Author
      Flash Havoc 4 years ago

      Hi Zia,

      There is no mention of this, other than heat protection in general. Though I’ll test it out at full power to see what happens.

      There is no fan in these CononMK strobes as far as I know.

      There is no lower power limit with HSS. I’m not sure if the AD600 have a limitation there either.

    • Author
      Flash Havoc 4 years ago

      Hi Zia,

      Thanks for the heads up, yes I spoke to CononMK about this as they look to be interesting little strobes.

      At this stage they are only available to K4T and i6T EX customers, to help support those systems (and using the same ABC transmitter units).

      Interestingly the run on 8 AA batteries, and a little unusually come supplied with Ni-cad rechargeable. Though regular NiMH Eneloops etc will work as well.

  12. Zia 4 years ago

    hy. is there any chance you can compare the ad 360 and the cononmk i6T EX Leopard in the same modifier, i don’t really understand – the power of the i6T EX Leopard (600W) F 45, 6 and the k4s (400w) has f 45 very similar f and very different W power, so i reallly have no idea what the real power is.

      Flash Havoc 4 years ago

      Hi Zia,

      I just spent over 6 hours comparing a number of strobes in different modifiers, though unfortunately the results were all inaccurate as I didn’t realize the dome had slipped down slightly on the light meter 🙁

      I redid some tests just in a 28″ Glow Parapop (with both diffusion fabrics), and using the same 7″ reflector. The other modifiers gave a different perspective in places, though this gives some indication –

      (28″ ParapPop result shown first, then with 7″ Reflector)

      RoveLight RL-600B – F22 +0.4, and F45 +0.1

      Godox AD600B TTL – F16 +0.5, and F32 +0

      Godox RS600P – F16 +0.4, and F32 +0

      Indra500 TTL – F16 +0.3, and F22 +0.5

      CononMK i6T EX TTL – F16 +0.1, and F32 +0.4

      CononMK K4T TTL – F11 +0.5, and F22 +0.8

      Godox AD360 – F11 +0.4, and F22 +0.2

      YongNuo YN300W – F8 +0.9, and F22 +0.1

      UPDATE – The CononMK i6T EX does actually provide almost a full stop more light in power extension mode (which increases recycle time from 1 second to 3 seconds). So I have updated the results above to show that. Results in the 7″ reflector and a beauty dish (not shown) put the i6T EX near the top of the list.

      I have also added the Godox AD600B results.

      • Marco 4 years ago

        Thanks so much for your tests.
        So taking in account the dimension and weight (i would like to use these units in reportage and corporate photogrphy and i really would like to travel as light as possible) tha godox ad360 or the cononmk k4t seem the way to go. If i understand well and the rovelight is really a 600ws it seem the i6t ex act as a 150ws (almost 2 stop less power) i am right, and globally only 1 stop more powerful then a top line speedlight, it’s correct?

        • Ulysses 4 years ago

          Marco, I was wondering very similar things. However, in a recent post, the Flash Havoc mentioned that the RoveLight is actually about 1-stop more powerful than advertised. If this is consistently the case, then it would mean that the i6T EX is behaving more like a 300 Ws strobe, which is consistent with his results from the AD-360 (also a 300 Ws light).

          In either case, it means that the i6T EX isn’t behaving the way it should. Not even close.

          • Marco 4 years ago

            Looking at the data posted the i6tex seem closer to 2 stop less powerful than the rovelight (22 +0.4 vs 11+0.1) with the same modifier. So looking at these data it’s 4 times less powerful. May be the roveligt effective power is more than 600ws?

            • Ulysses 4 years ago

              Yes, that’s exactly what i was saying. 🙂

              Flash Havoc has mentioned in the past the RoveLight is approximately and effectively 1 stop more powerful than advertised.

      • Zia 4 years ago

        tks this is very helpful

      • Niels Gram 4 years ago

        Thanks Flash Havoc !
        It seems that there was a good reason for the super fast recycling of the new CononMK 🙁 I’m quite disappointed. Any chance of the AD600 being added to the test ?

        • Paul Rumohr 4 years ago

          So it seems there is no free lunch.

          A unit that would do it all would have the power, output, battery capacity, and sustained HSS capability of the Rovelight, the TTL accuracy of a name brand speedlight, the size and weight of a Godox AD360, with a universal mounting system (like Bowens).

          I think the Indra 500 is looking like a pretty good compromise here, and possibly the AD600 if it’s output intensity and recycle are comparable (too bad about it’s overheat protection feature kicking in in HSS).

        • Author
          Flash Havoc 4 years ago

          Yes, as mentioned further below I’ll need to do them all again with the wider range of modifiers, but I’ll wait for the AD600 this time as I’d like to compare that in exactly the same setting. Hopefully the AD600 should come in a week of so.

          The i6T EX are not as bad as those figures make it look. In a beauty dish for example they are not that different to the Indra, but the recycle time is like chalk and cheese in comparison. The i6T EX are hard not to like.

          UPDATE – The CononMK i6T EX does actually provide almost a full stop more light in Power Extension Mode (which increases recycle time from 1 second to 3 seconds). So I have updated the results above to show that. Results in the 7″ reflector and a beauty dish (not shown) put the i6T EX near the top of the list.

          I also added the Godox AD600B results.

          • Paul Rumohr 4 years ago

            OK, so let’s accept the i6T EX as it is and take a look at what it does.

            f11 in a 28″ Glow Parapop, maybe a half stop more(11.5-ish) in a beauty dish at what I assume is a photographer’s average working distance with these modifiers.

            2.4GHz Radio, TTL with Canon Nikon and Sony, HSS, 1 second recycle time, bright(-ish) model lamp, Li-on battery, an optional bowens mount adapter, and a total weight of 2.26kg or 4.98lbs.

            Those are not bad specs at all. But at a retail price of $1,000, it does make you think seriously about the other options.

            Particularly the AD600 at a slightly heftier 2.9kg (6.4lbs) IF it’s popping out 500 flashes at f16.4 like the RS600P at a 2.5 sec recycle. Looking at those numbers it might have the same recycle time as the i6T EX at similar lower power levels.

            I wish everyone on the forum lived in the same town! We could all go over to Elv’s place to help him test the crap out of all these new strobes!!

            • Ulysses 4 years ago

              Paul, I was thinking the same thing. Even IF Elv’s initial test told us the entire story about the i6T EX (and as Elv already said, it does NOT yet tell the whole story), you’re still left with a very impressive strobe for all the reasons you mentioned. So it would come down to whether the photographer was shooting with mixed camera gear, needed fast recycle time, an onboard battery, and HSS & TTL.

              On the other hand, if you were more in the market for a full-featured strobe that also has compatibility with a range of flash and transmitter products, then the AD600 would be a serious contender, even with a few warts here or there.

              Once we get over our stats fever and our collective desire to compare every minute detail, we can actually start to enjoy these pieces of gear.

  13. Ulysses 4 years ago

    First of all, THANK YOU for the extensive and tedious tests. Sorry about the wasted time with the slipped dome.

    But importantly, WHAT in the world happened with the i6T EX ???? This is supposed to be a 600 Ws strobe, isn’t it? From those numbers, it’s acting more like 300 Ws. Will you need to inquire with CononMK about that?

    Thanks again!

    • Author
      Flash Havoc 4 years ago

      Its a little strange really, and I wish I had all the accurate results with other modifiers as well as bouncing off the ceiling etc, because they do show some different perspectives. Some that are only going to be explained by seeing the light pattern produced.

      The protruding flash tube of the i6T EX appears more efficient in modifiers like a beauty dish and Phottix Luna softbox / beauty dish. Where the K4T has the built in reflector which pushes more light directly forward in regular softboxes etc. So the one figure above does not completely do the i6T EX justice.

      Overall I would say the K4T and i6T EX are pretty well around equal output, [ UPDATE – In Power Extension Mode the i6T are aproximately 0.7 stops ahead of he K4T ], and overall combined weight is a little less with the i6T EX. Though the i6T EX recycle lighting fast in comparison [outside Power Extension Mode]. Its really hard not to like that strobe. The K4T is a featherweight though in comparison, if you have the relatively lightweight pack on your belt etc. Its hard not to like that flash either.

      A few things that did stand out though, is the smaller 5″ reflector of the RoveLight, and 6″ reflector of the Godox RS600P are pretty inefficient at concentrating the light in one area, and lose over a stop over he standard 7″ reflector. I knew the diffuser disc did that, but I didn’t realise the bare reflectors where just as bad. The RoveLight has power to kill though anyway.

      The other thing is went through the LED modelling lights, and the Godox RS600P where the only one to come pretty close to matching a regular 150W inside a softbox. If the AD600 are the same this is good news.

      The others are down at least a stop, with the Rovelight and Indra the lowest around 2 stops down. The i6T EX has a great modelling light with a number of options including auto to follow the power levels. Around one stop (75W aprox) in a modifier, though matching the 150W in a 7″ reflector.

      The Indra certainly still has the nicest build quality of the lot, though theres nothing particuarly bad about the others either.

      I’ll have to do the tests all again, though I’d like to wait for the AD600 this time (should be coming in a week or so) to compare that in is exactly the same setting as well.

      One initial report I have is the AD600 was around 1/3rd of a stop less than the RoveLight. If that turns out to be correct the AD600 are looking very promising.

      Probably the more significant factor will be color variation across power levels. I’ve never really heard anyone even mention the Indra for example was not enough power for them.

      • Ulysses 4 years ago

        Elv, even though I know it’s very early on in your evaluation of several of these strobes, THANK YOU for these early impressions with your “first look” at some of them. As you can tell, interest is running VERY high in this category of strobe. With so many options coming out in the 300-600 Ws range, it looks like 2016 is going to be a very interesting year to buy and experiment with lighting for pros as well as serious enthusiasts.

        You also hit the nail on the head with regard to color variation across power levels. Having personal experience with the Indra500, I can attest to how annoying and even disappointing this issue has been in some real-world shooting situations. If you’re in mixed lighting, it’s not quite as noticeable because there are crazy mixes of light sources coming from so many places that you simply go with it if your strobe is powered at a low level and goes completely blue. But if you’re in a situation where things are more controlled and predictable, and your Indra500 needs to be at a very low level for the shot to work, it’s very frustrating that there’s not much you can easily do about the color variation. It’s very consistent, though… anything at 1/32 or lower gets very blue/cyan, a problem especially when shooting under incandescent lighting.

        I sincerely hope this isn’t a problem for the AD600. It would make me even less inclined to buy it.

        • Paul Rumohr 4 years ago

          Is anyone aware of color variation in low power shots with Profoto B1 and B2 Airs? I would hope for the price that it would be minimal.

  14. Ulysses 4 years ago

    Paul, you can see at least one photographer’s tests for color consistency in his comparison of the Indra500 and Profoto B1 500 TTL. It’s mostly consistent with what I’d reported, but more detailed in his findings. But I’m not sure why Profoto is able to achieve their color consistency while Phottix engineers cannot. It’s a real puzzle, and I’m not sure a firmware update is going to fix it — or rather I’m not sure their engineers are going to fix it.

    With the Profoto B1 apparently part of what you’re paying for is color consistency. But you can also find similar consistency with other lights. So I don’t know what Phottix’s hangup is.

    • Paul Rumohr 4 years ago

      Thanks Ulysses. I wasn’t aware of the color issue with the Phottix Indra in TTL or under 1/32 power. Also the banding in HSS at 1/8 power. What a bummer!

      Now I’m going to have to hunt down articles on the Rovelight’s color consistency, because that’s kind of what’s left available in the sustained fire HSS department :/

  15. Paul Rumohr 4 years ago

    Hey just on an unrelated note, the i6T EX batteries are 2000mAh… is that right?

    Did they go and make a strobe unit that actually uses a battery that has 600mAh LESS than my tiny Canon 5D 2600mAh camera battery?

    • Ulysses 4 years ago

      To be fair, or rather to provide broader perspective: While I also observed the banding at 1/8 with HSS issue in my unscientific informal testing of the Indra500 system in a studio setting, I haven’t noticed it in actual real-world shooting. In other words, those test situations are ideal for showing that sort of problem, but you’re unlikely to see it often (or at all) when shooting and lighting real subjects.

      It’s similar even with the color shift. Yes, it’s definitely there. I’d also say it’s a more obvious problem than the darker band issue (which is likely a simple timing problem and could be fixed with firmware). But as I’ve alluded earlier, it’s less of a problem in most situations than might be expected when looking at lab tests. So if the totality of the Phottix system interests you (flash with master control, strobes with HSS and/or TTL, and radios to tie it all together), I’d still keep this light on my short list. There aren’t many systems available that do what it can do, even though it’s not perfect.

    • Niels Gram 4 years ago

      @Ulyssus: Did you try to upgrade the Indra firmware ?

      • Ulysses 4 years ago

        I haven’t yet upgraded my firmware, but I know a few others who have. Unfortunately, it did not change anything in regard to the color inconsistency we’ve seen or in Joakim’s test at the page link I mentioned earlier (the Indra500 vs Profoto B1 test).

  16. Zia 4 years ago

    the email from cocnonmk about the power issue: About the question you mentioned, it did has 600WS power. Compared with real power, there is one aperture short for fast flash and fast recycle.
    When in power expension mode and green light on, it is 600WS. Power = capacitor capacity X voltage

    • Paul Rumohr 4 years ago

      LOL!! Power expansion mode? They actually said that?

      I am on the floor. Someone get me when I’m finished laughing.

  17. Darryl 4 years ago

    These lights with the respective ws may not be comparing apples to apples with respect to light output. If one unit has 500ws but is more efficient then it would produce more lumens at the same ws.

    • Niels Gram 4 years ago

      @Darryl: That’s exactly right. The Ws measure only the amount of energy stored in the capacitor. The amount of light which is generated and how it is distributed when the capacitor is being discharged through the flash tube will vary a lot from flash to flash and also depend on modifiers used… Ws isn’t a good measure for flash light output.

  18. Niels Gram 4 years ago

    From the Indra 500 fw 1.06 release note:
    “3. Addition of a Color / Action option for M (Manual) mode to improve color temperature
    in Custom Settings Menu. To use: Hold the menu button, and, Press and rotate the
    control knob access the Custom Setting menu.
    “Color” mode offers more stable color temperatures of
    5500K +/- 200K, but does not support HSS.
    “Action” mode supports HSS but color temperature variations of
    5500K +/- 400K.”

    So it seems you can’t just upgrade the firmware and expect things to be better. You need to select “Color” mode to see any improvements. It’s not clear to me if “M (Manual) mode” is power level dialed in on the flash or if it also covers M mode on the Odin.

    The color shift seems like such a bummer to me that if I had been Phottix I would have made a special mode without the pre-flash for M mode on the Odin (which would probably not support TTL at the same time). I can only conclude that I’m very happy that I haven’t invested in an Indra 500 because this color shift issue would have made it unusable for me 🙁

  19. Ulysses 4 years ago

    Yes, as alluded earlier Joakim and a few others have installed and tested firmware 1.06. Joakim mentions:
    “I was able to test the new firmware today. I’m sorry to report back that the firmware update didn’t change anything. If there was a change, I didn’t see it. If you want decent color consistency with Indra500, stay out of TTL and changing power through the Odin remote. Or stay above 1/4 power at all times. Only the new Odin II remote can save us now.”

    To illustrate what his findings were in the context of his original test (at the link I mentioned earlier), he says:
    “I tested the new firmware 1.06 for the Indra500 and came to the conclusion that there was no improvement. In “color mode” the following numbers are telling: Fully manual vs power level set on Odin remote:
    Power level 1/128: 6350k +1 tint / 8700k +24 tint
    Power level 1/64: 6300k 0 tint / 7500k +17 tint”

    So… here we are. But I again, I want to reiterate that while this can be greatly annoying, the Phottix system still offers some rather unique things, which may or may not be more important to you than absolute color consistency. Depends upon how you shoot, what environments you tend to shoot most often, and what gear you’re looking to work with. At least knowledge is power. LOL

    • Niels Gram 4 years ago

      Sorry, I missed the “in “color mode”” in the second quote…

  20. Zia 4 years ago

    So i tested my Ad360 and at 1/125 in HS mode I lose 1 stop power. In manual mode at 1/125 the flash is 1 stop more powerful than the HS mode. I understood from Cononmk that the I6 in expansation mode 3.2 recycle time is 600w and in fast recycle time 1 second recycle time you lose 1 stop of power because it uses HS pulse sync. When you tested the output of the flashes was the Cononmk i6 in fast recycle time mode or in power expansation mode? Thanks again for all the tests you make. Really apreciate it.

  21. Niels Gram 4 years ago

    The i6 T and other flashes e.g. the Elinchrome ELB400 has an exposed flash tube ( and the trigger electrode is exposed and could without doubt be touched by accident. I’m wondering how this can be safe – the trigger voltage is often in the kV range . Could someone enlighten me please 🙂

  22. Niels Gram 4 years ago

    Anyone with an opinion on exposed trigger electrodes ?

    • marco 4 years ago

      Niels, pratically all the strobes use an exposed bare bulb (i Use profoto D1 and they are different, but that’s worst to fill a big softbox) .
      when the flash is in use the head is inside a softbox or a reflector. if you want to use the nud flash just pay attention

    • Author
      Flash Havoc 4 years ago

      There are no electrodes exposed unless you were to break the flash tube.

      In which case its pretty unlikely you’re going to be firing the strobe (while pocking your fingers into a broken flash tube).

      You could certainly burn yourself though if you were silly enough to hold the flash tube while firing the strobe.

      The i6T EX have a frosted glass dome to cover the flash tube though anyway.

  23. Niels Gram 4 years ago

    Thank’s Marco and FlashHavoc. If the i6T EX can’t be used without the frosted glass dome in place then there is no issue but the Elinchrome flash does not have a frosted glass dome. The wire spiraling around the flash tube is the trigger electrode. There are other options for triggering the flashtube than using external trigger so the fact that the tube clearly has an external trigger electrode does not mean that it is actually used but external triggering is the most common method for triggering – especially for photographic flashes. See and for more details.

      Ok sorry I see what you mean there.

      I really don’t know, though I wouldn’t like to try touching it to find out, because the least you would do is likely burn yourself. There must be something more to it though.

  24. Josh 4 years ago

    So am I reading this right? My Canon 600ex rt flash will trigger this strobe?

    • Author
      Flash Havoc 4 years ago

      Hi Josh,

      The Canon 600EX-RT is not directly compatible with the radio system of the i6T-EX.

      And the I6T-EX does not have a Canon Optical Wireless slave mode either.

      So the main way you could trigger the strobe with the 600EX-RT would just be using the basic S1 and S2 optic slave modes on the strobe. That is in manual only doesn’t provide any remote control.

      I haven’t tested this, though you could possible use a YN-E3RT radio receiver and just to fire the strobe from the 600EX-RT, and the CononMK ABC receiver to remotely control the strobes manual power levels.

      In general though at this stage you need the ABC transmitter on the camera hotshoe to have full TTL and control of the remote strobe.

  25. Zia 3 years ago

    have you tested the hss on the i6t ? dose it work without gradient at any power ?

  26. Craig 3 years ago

    Can you comment on the weight of this? The Cononmk site ( advertises the i6T-EX as weighing 1.8kg (1.4 body plus 0.4 battery), whereas your article states 2.1kg with battery. Is their measurement without flash tube, glass dome, and light stand mount or something? It would be awesome if you could provide weight of individual parts in the future.
