PROFOTO B10 250 AirTTL – Cordless Flash Announced



Profoto have announced the B10 250 AirTTL compact cordless TTL and HSS enable flash and continuous light.

Now featuring a variable color LED light, and built-in Bluetooth connectivity, providing remote control via smart device and the new Profoto APP.

As well as an AC battery charger which can now be charging while the light is in use.

The compact 250Ws B10 provides the light output of a number of speedlites combined, with a full power recycle time of 2 seconds, and up to 400 full power shots per battery charge.

As something of a first, the B10’s 2500 Lumen LED light is color temperature adjustable, from 3000K to 6500K. Providing up to 75 minutes of full power run time per battery charge.

What was once a modelling light, is now a “continuous light”, which will speak to many wedding photographers transitioning to the era of full frame mirrorless cameras, and What You See Is What You Get, still and video lighting.





On the flash side, the B10 features TTL, HSS, and a 10 stop manual power range, from 1/1 to 1/512. Adjustable in 0.1 stop increments.

As well as a Freeze mode providing short flash durations down to 1/14,000s t.1 (1/50,000s t.5).

6 flash Groups are provided: A / B / C / D / E / F.

And TTL and HSS enabled Profoto Air Remote radio transmitter units are now available for Canon, Nikon, Sony, Fuji, and Olympus, cameras systems.

Profoto A1 speedlites also provide a transmitter function for wedding and event photographers requiring a flash mounted on the camera.




At just 17.5cm long, and weighing 1.5kg, including battery and swivel mount, the B10 are a fraction of the size and weight of the their big brother B1X 500 AirTTL.

And much more like the light we had originally expected to see from Profoto nearly 5 years ago, when they first teased the coming “Off Camera Flash” concept. Which turned out to be the somewhat hefty original B1.

For many situations the B10’s size and weight will provide a much more manageable alternative. And the lights compact metal swivel mount also doubles as a built-in handle, which is also quickly removable for even lighter monopod / Gorrillapod mounting etc.

Most importantly the B10 are directly compatible with all of Profoto’s 120 full size light shaping tools, as well as the lightweight dedicated OCF (Off Camera Flash) modifiers.

Once again the B10 feature a recessed flash tube, providing a built-in reflector with protective glass cover.

The built in reflector making for easy use with optional Profoto OCF gels and grids.

OCF Zoom and Magnum reflectors are also available to concentrate the light and increase intensity by 1.2 and 1.8 stops respectively.




New to the OCF range of lights is the B10’s ability to recharge while the light is in use, effectively providing an AC / DC power option for the B10.

And the battery charger is designed to strap neatly to the light stand below the light.

The B10’s battery will recharge fully in 90 minutes, or to 80% in 60 minutes (while not in use). And provides up to 400 full power flashes, or 75 minutes continuous LED light at full power.




Another significant new feature and addition to the Profoto system is the new Profoto APP (Beta), and Bluetooth connectivity built directly into the B10 lights.

The APP provides full control of the Profoto Lights, including color temperature control with the B10’s new adjustable LED light.

Current flash power levels are also displayed live on the APP interface (at the time of writing this, a feature strangely still lacking from Profoto radio transmitters), and flash firmware updates can now be made through the APP and Blutetooth connection.

The APP also allows your smartphone to act as camera while using Profoto lights. Though its not clear if this is actually syncing with flash, or just using the continuous light at this stage.






One unusual omission from the B10 is any from of Sync port? (leave your backup PocketWizards etc at home).

Though there is at least a basic optic slave unit included.

A Type-C USB port is included for firmware updates.




The B10 are available in Single or Duo kits.

With the Duo Kit including a nicely designed backpack (valued at $249 when purchased separately).


PROFOTO B10The Profoto Core S Backpack has been purpose designed with careful consideration, to carry 2 B10 lights, as well as camera gear and 15″ laptop.

Also featuring built-in expansion with roll top, and external straps for mounting compact light stands and tripods etc.









The Profoto B10, and B10 Duo Kits, are available for pre-order now from $1595, and expected to ship near the end of October 2018.

    Nice hardware, crazy price.
    I’ll stick with my Flashpoint stuff to get the picture.

  2. John Wilson 3 years ago

    Nice, detailed post. I hadn’t seen the flash duration specs before.

    No colour consistency specs but that’s normal for Profoto isn’t it?

    The sync port omission is very odd.

    Like the AD400Pro the swivel mount is removable.

    The app is Apple only (at least at the moment).

    I wonder if the power of the LED changes when you change colour temperature (like a bi-colour panel does).

    Seeing it’s priced $200 less than a dual pack of A1s it’s pretty good value by Profoto standards.

    The LED would seem to be 30-35W is that about right?

    • Mark 3 years ago

      The omission of a sync cord is less odd these days as the bulk of users have adopted radio triggers. It saves money not having it.
      Back in the late 80’s radio triggers were an expensive Godsend for our wedding business as we were using optical triggers for our OCF. Guest flashes triggered them a fair amount, sometimes at key moments.
      In the studio a sync cord was the sure fire way to make sure someone tripped over it and on location it was the one thing sure to fail.
      Good riddance.

      • John Wilson 3 years ago

        Lack of a sync port also means you can’t use 3rd party triggers like PocketWizards

        • Mark 3 years ago

          As PWs are some of the most unreliable triggers I have used I scarcely think this is a drawback.
          Even the $13 Yongnuo triggers outperformed the PWs every day.

    It looks like a great kit.

    After so many years of Norman and Qflash it’s amazing to see so many portable flash options being developed.

    A true AC power adapter would be better than a charge as you shoot option.

    A 400w version would be a killer combo.

  4. adam 3 years ago

    Seems like from a specs point of view the ad400 is the way to go with more power and faster recycle in a similar sized package.

  5. Ricardo Gomez 3 years ago

    It’s just hard for me to believe there are enough professional or well-off amateur photographers that see the value of gear priced in this area. I think Profoto collapsible light modifiers have a reasonable premium to justify them. They are built like tanks and there is something special about the quality of light from them. Come to think of it, I’ve never used Profoto heads with them either.

    More power to them if they can get the premium. Every business’s dream!

  6. dogwood 3 years ago

    Never liked profoto prices, and why i dont buy them new, but compared to others brands there’s nothing that bother about them (again except for pricing). Id rather wait until i can afford the best rather than buying something with compromises

  7. Andy 3 years ago

    I really like the specs of the 400PRO but for me weight is a real issue and the 1.5kg weight of the profoto and its smaller size ticks a few boxes for me.

    The Profoto head is light enough to go on a nano stand which again means less weight for my kit.

    Less power than the 400PRO but more weight and size.

    The cost is more than double the price of Godox and a two head kit is coming in at £2800 rather than £1400 for two Godox.
    I imagine the extra spare batteries will also be expensive.

    Again I think it’s wonderful that Profoto are now quickly developing new products to provide a portable eco system but at least Godox isn’t too much of a compromise.

  8. Tim 3 years ago

    Fstoppers did a test and found the power to be 2.5 speedlights vs 5 speedlight Profoto claimed.
    YouTuber found AD400 is only 4/10 stop weaker than AD600Pro!

    This is great if you don’t shoot HSS and indoor but AD400PRO is more versatile for weddings.

    • John Wilson 3 years ago

      Do you have a link to that article? I can’t find it on

      Youtubers find all sorts of things.

  9. Tim 3 years ago


    Here you go.

    For power comparison, it’s under power.

    • John Wilson 3 years ago

      Ah that one! Yes, I saw the video. That was a “test” done in an hotel room by a couple of guys who went to the launch of a strobe without taking a light meter.

      I think their claim that it’s as powerful as 5 speedlights is doubtful but I don’t give much credence to this test.

  10. Rian 3 years ago

    I do want to love these, the AD200 and AD400pro put these two in an uncomfortable position. I would be happy to invest into Profoto. Their light modifiers and quality is fantastic, never used more reliable triggers than the air sync back in 2008 it was even a good deal in contrast to pocket wizards.

    But Godox is smaller and lighter with the AD200 + round Fresnel head with comparable specs.
    Ad400 is slightly heavier but a good option should more boom be needed.
    2x AD400 and 2xAD200 with full options are still cheaper than only 2xB10 – hard to justify IMHO especially as the Godox system has proven to be EXTREMELY reliable to me with tons of stores selling their chargers or accessories within my area here….

    AMAZING product! really well done profoto. people will buy it. I won’t, simply too happy with AD200 and fresnel head option.

    • John Wilson 3 years ago

      Hi, Rian! The Godox AD200 round head is not a fresnel. It’s the tube from the bare bulb head mounted horizontally in a reflector with some diffusion on the front. So you get no nasty fresnel artifacts at the edges of the light.

      • Rian 3 years ago

        You are 100% correct, I was in a hurry and mixed up the words fresnel and bare bulb. everywhere you read fresnel just void it and replace with bare-bulb, then my text makes sense.
