Introducing The Profoto B1 Battery Powered TTL Monolight

Introducing The Profoto B1 Battery Powered TTL Monolight

Announced this morning by Profoto was their newest light in their lighting kit, the B1 Off-Camera Flash. Refusing it call it a speed light or a studio strobe, the completely cordless B1 Off-Camera Flash has some truly unique and interesting features not seen before in a studio strobe. Update - Now available on B&H for Preorder at $1,995.

Perhaps the most remarkable feature in the B1 Off-Camera Flash is that it is cordless. With a battery pack equipped within the unit itself allowing up to 220 full power flashes (with removable battery), the B1 looks to appeal to the highly mobile photographer. It also includes some incredible features like TTL built into the unit itself, allowing you to use your camera’s settings to decide on the power of the unit (with the use of their Air Remote TTL). The unit also packs 500w/s, which is more than enough power to meet your needs.

They also boast the speed of the unit. With up to 20 flashes per second (at low power) and a recycle rate under 2 seconds for full power, the B1 will be able to offer a great alternative to those using speedlights as off camera flash units. You can of course also expect to see all the great features contained in a standard Profoto light, with their zooming head, and mounting system that works for all current ProfotoUSA lights.

UPDATE -

Profoto B1 500 is available for Pre-Order on B&H Photo for $1,995.

PREACH!

Church!

If this is under $3k, I know what I'll be investing in. Will make shooting on the streets of NYC far easier.

The Profoto retailer for Switzerland already has it up on its webshop for CHF1'980.- (about 2'150-2'200$US).

Those B1 look very much like Priolite's strobes. However, the addition of TTL is quite interesting. Might think about selling my Ranger RX and not buying a Quadra but one or two B1 instead.

I'm just disappointed by the t0.5 duration at full power! 1/1000th isn't what I'd call short duration :/

This is the ultimate wedding photographers monolight. I can't wait.

I spoke too soon, these can't plug in to AC power at all :(

Do you really need to? Personally, I would just use these for portraits and carry an extra battery pack or two. That will give you 660 full-power and realistically double that flashes. Should be enough for any wedding I would think.

I think it still could be the ultimate wedding photographer's light because ask yourself: "How often am I using a 500ws light at full power for (groups, reception, etc.)?" ... Meaning, how many shots are you using 1/1? Not many, I'm sure.

I rarely have had to go over 1/4 on a 580EX II for a typical reception and still had plenty of juice at the end of the night with just 4-AA batteries.

All that being said, it would be nice to have an AC option.

Give Profoto a few months and they'll have $300+ dollar clip on AC power adapter (it'll clip on where a battery normally clips on).

But can it do High Speed Sync?

Christopher Hoffmann's picture

Not at this time.

Now THIS is what I'm talking about!

WANT. The only disappointment is the t.05 duration, but everything else it awesome.
Just gotta see the price.

I 've already played with them, these things are cool!

Lee Morris's picture

Can this thing also work on AC power? I hope so

Sadly, no

Lee Morris's picture

NOOOOO!

The price do makes up for this!

I was just thinking that.....90 mins of modeling light isn't enough for my interviews! Why wouldn't they put an AC cord input just so you could have that option?

Yeah.. if you professional who has the 2k - 6k to spend on lights. From the comments I'm reading from all the pro photogs here, this probably isn't a viable solution for big shoots and the price point is too high for the amateur photographer. I could see myself paying up to 1000 for a great light unit, but think I'm just going to stick with my current set up.

lol my thoughts exactly. haha

that makes no sense ...profoto .. smh :(

How do you recharge it ? Surely you can't just charge it while shooting with it? So it draws from the battery but it's charging at the same time.

You put the charger directly into the battery. When the battery is in the unit, the port is covered.

Shouldn't take too long for some 3rd party to spec up an AC/DC converter that matches the shape of the battery/contacts.

Forget the TTL, with AC power they would be PERFECT! I'd be SOL if I were on a 12hr shoot and the lights ran out of juice. Even if I had 2 backup batteries that would be *only* 660 full power shots for 1 light.... sigh

"Adding AC power would only have made them bigger and more expensive" was the answer i got when i asked about AC options. If you don't need TTL there is still the B3 1200.

that makes no sense ...profoto .. smh
