ORLIT RT-600C – TTL Speedlite Released



Adorama have announced the ORLIT RT-600C TTL Speedlite, providing both radio Master and Slave modes directly compatible with the Canon RT radio system.

Released alongside the ORLIT RT 610 TTL Cordless Strobe, the RT-600C Speedlite are Adorama’s version of the recently announced Jinbei 600EX-RT Speedlite. And both lights in the USA are available exclusively from Adorama.

At the time of release the ORLIT RT-600C are only the second, third-party speedlight currently available to provide both radio Master and Slave modes compatible with Canon’s 2.4GHz RT radio system.

The RT-600C have stepped up though with more attention to detail, and now featuring most of the more advanced features provided with the original version Canon 600EX-RT Speedlite, including –

  • Gel holder and color temperature sensor
  • Auto exposure sensor, and Ext.A  / Ext.M modes
  • 3 LED AF assist light
  • Flash head tilt & swivel lock button
  • Tight foot with advanced lever lock
  • Full 600EX-RT Custom Functions and Personal Functions
  • UPDATE – USB Port for firmware updates now added



The Orlit RT-600C provide similar power to the original Canon 600EX-RT, with a guide number stated as 55m (ISO100 / 200mm).

As well as providing 20-200mm zoom, ETTL, HSS to 1/8000s, and Second Curtain Sync etc.

Full power recycle time is under 3 seconds, and an external HV battery port is also provided.

A dot matrix LCD screen and interface are all very similar to the original 600EX-RT.

Like the original Canon flash, the Orlit RT-600C provides both Canon Optic Wireless Master and Slave modes, along with the RT radio Master and Slave modes.




Unlike most third party speedlites, Orlit have included the gel color temperature sensors located under the flash head. (Which can automatically adjust the cameras white balance setting to match).

And a 600EX-RT style gel holder and CTO gel are be supplied with the flash.

Also very rarely included in third party version of the Canon speedlites is an Auto Exposure sensor located on the front of the flash, and Ext.A / Ext.M flash metering mode.



The Orlit RT-600C provide a Canon style external HV battery port, and PC sync port.

UPDATE – And now also a USB port for firmware updates (located inside the battery compartment).




The Orlit RT-600C also provide a multiple beam AF assist light. With different combinations of the 3 LED lights engaged depending on the AF points selected in the camera.

This is still not quite the same as Canon’s AF assist lights though, as all 3 lights in the RT-600C project vertical line patterns, just at different sizes. Still much better than most single LED systems though.

    Give them Li-Ion and I’m on board. Until then Cheetah flashes rock.

    Third party and no firmware update compatability is a joke… new cameras can’t work with it ugh

  3. jim 4 years ago

    will wait for reviews

    Wanting to clarify, Adorama states this model does have a USB port? Which is correct?

      Hi Omar,

      I think that must be a mistake, because I can not see a USB port anywhere in the flash.

  5. Jeff S 4 years ago

    No USB, however, it seems to be nicely built, performance is good, has a signal checker, and works with other Canon and Jinbei RT devices like the Orlit 610. Picked up one last week and two on sale (24% off at Adorama this weekend).

      Hi Jeff,

      Thanks for that. Did you try the flash mounted on the camera? If so how did you find the base level TTL exposure? And also how are the FEC adjustments if you go over + or – 1.0 FEC?

  6. Scott B. 3 years ago

    Adorama, has a sale on the Orlit Rt-600C right now for $89.95 + shipping. and according to the pictures on Adorama’s website, it does show that there is a USB port for updates…

      Thanks Scott!

      It does indeed look as though a USB port has now been added.

      And Jinbei appear to have a placeholder for the firmware update on their website as well.

      With the early version I have, you need to wind on over a stop of FEC to get a similar TTL base exposure as the Canon Speedlite. And also FEC adjustments are not in equal graduations. That may have been refined by now, though in any case the flash itself is built well, so that’s a very good price now that they can be refined with firmware later if needed.

    So I just purchased the two of these flash units and had some issues while shooting with them paired up with the 610. One unit overheated on me, but this may have been due to overshooting with HSS. The other unit had issues staying connected, and re-pairing with the transmitter. I’m going to be getting in touch with their tech staff in hopes that a firmware update is on the way to help with these issues, which both can be critical when shooting a paid gig. Luckily I had my pocket wizards to help stay connected and push through the shoot, but even then ran into a few issues on that side as well. (Note I haven’t had time to update the RT-610, and TR-611’s firmware yet so this may help with some of the issues displayed)

      Hi Damien,

      Thanks for the feedback. I’m not sure that the TR-611C are very good in general though. The later TR-Q6 transmitters appear to be considerably better, with the RT-610/601 strobes at least.

      The other issue has been the Canon 5D mark IV camera (I don’t know if you may be using that) which Jinbei have apparently acknowledged has some weak radio connection issues with their RT gear. They are recommending their own RT transmitter as the best solution, though I still find the original Canon ST-E3-RT is working the best even with the 5D mark IV.

      • Damien McLean 3 years ago

        I’m shooting with the 6D MK1 which in the past seems to have some issues with wireless units like the Pocket Wizard mini tt1 so maybe some of the issues may be stemming from that? I’ve also ran into some issues on my last shoot where the RT-610 was firing a few seconds after the shot was taken, not sure what that was all about. I wasn’t shooting with a longer exposure or second curtain.

        I almost picked up the TR-Q6 with the purchase of the RT-600’s, but didn’t because I like the option of having a hot shoe mount to incorporate my other flashes if needed. You’re right about the TR-611C though. Straight out of the box it seemed very buggy.

        • Damien McLean 3 years ago

          ***Quick note (not sure if this is in the manual) but if you are to use the hot shoe mount on the TR-611C group A must be turned on in order to trigger it. This would have been helpful to know the other night as well when I was trying to expose for the back light and couldn’t figure out why it wouldn’t flash at certain times, lol.

    I have a Sony A7R3 and I just purchased the TR-Q6 to trigger my 610 Strobe. I also want to purchase one of the Orlit Sppedlites but I am not sure if I can control it from the TR-Q6? I do NOT require TTL and plan on using it manually.
    From what I can surmise it should work fine, it state the Speedlite works with the RT lights but if someone here knows for a fact it works I will feel more at ease about ordering a couple Speedlites.

    • Tyler Moncrief 3 years ago

      I’d like to know that too. Been searching for this answer for months now

      I just switched over to Sony and need to know if the Orlit TR-Q6 can fire the Orlit Speedlite, even if it does have a canon infrastructure built into the flash unit

      I’d like to use the a6500 with the TR-Q6 attached, to fire a Rovelight 610 as my key light and a RT-600C as my hair light

      I don’t see why it couldn’t since everything is Orlit. I’d just like to know this before I jump into the system

        Hi Tyler, and Joseph.

        From what I can see the RT-600C only has the Canon RT radio slave mode available. So no it won’t work with a TR-Q6 transmitter for Sony or Nikon.

        The strobes like the RT-610 have multiple radio slave modes built inside for Canon, Nikon, Sony, and now Fuji as well. (Though even then you have to set the strobe to one radio system at a time, its not auto sensing like the Godox system where you can use different camera systems at the same time).
