Since its release in 2013, the B1 has taken the photographic community by storm.

The most attention-grabbing feature has always been the B1’s completely cordless TTL operation, reinforcing the fact that the B1 is not a studio flash. It is an off-camera flash designed for on-location photography. In addition to being portable and easy to use, the B1 is a professional flash in every sense of the word.

Fast enough to keep up with your camera and 10 times as powerful as the average speedlight, the B1 makes great light easy.

The Profoto B1

  • Patented AirTTL technology provides perfect exposure in a flash.
  • 500 Ws adjustable in 1/10 f-stop increments over a 9 f-stop power range.
  • Interchangeable, integrated battery provides up to 220 full-power flashes and tens of thousands at lowest power.
  • Patent-pending Profoto HSS is 10 times as powerful as your average speedlite.
  • Fires up to 20 flashes a second with flash durations as short as 1/19,000 of a second.
  • Designed for use with more than 150 Light Shaping Tools.

The B1 is fast and will easily keep up with your camera, shooting at speeds of up to twenty flashes per second.

Speed also equals short flash duration. With the B1, you will not only be able to capture the moment. You will also be able to freeze it in time with absolute sharpness.

Also note that the B1 has High-Speed Sync (HSS) functionality, giving you full control of the available light.


The B1 is the world’s first off-camera flash to do TTL with both Canon and Nikon cameras.

Canon shooters attach the Air Remote TTL-C to their camera’s hot shoe, Nikon shooters the Air Remote TTL-N.

Then point and shoot, and the off camera flash will automatically adjust its light output to provide you with the perfect exposure.

Light Shaping Tools

The B1 has a built-in reflector that creates a wide and even light spread that stands well on its own.

There is an assortment of compact and portable OCF Light Shaping Tools to choose from, including softboxes, grids and snoots. In addition, there is the entire family of Profoto Light Shaping Tools that have made Profoto the leader in professional photography.

Without Cords

Do you remember the feeling when you first learned how to ride a bicycle? Remember how the world seemed to open up, how you were suddenly able to go anywhere and do anything? then you know what it is like shooting with the battery-pwered and wirelessly synced and controlled B1.

Shoot indoors or shoot outdoors, miles away from the nearest wall outlet. Please the lights wherever you want. Your imagination sets the limits, not the length of our cables.
