We call the B1 an off-camera flash because it is not a speedlight and it is not a monolight. It is a new kind of flash that brings a whole new way of shooting. “Once you try it, it changes everything,” said Richard Walch, the first photographer who tried it. We believe that’s true.

Why? Because it has TTL, so you get a perfect exposure in a flash. Because it is battery-powered and cordless, so you can take it with you wherever you go and put it wherever you want. Add to that the power, speed and light shaping possibilities that Profoto lights are known for, and you have an off-camera flash that makes great light easy.

The B1 is not a stay-at-home flash. Its TTL function shines the brightest in challenging lighting conditions. Its cordless operation unleashes your creativity and makes it want to run free in the wild. The B1 Location Kit was designed with this in mind.

The B1 Location Kit includes 2 x B1 off-camera flashes, 2 x Li-Ion batteries, 1 x Fast Charger (recharges the battery in one hour) and 1 x Car Charger (charges the battery from a standard car cigarette connector) . Bring it with you wherever your creativity leads you. Who knows where it will take you?

Karolina Henke says that her best images are shot in the spur of the moment, capturing something unforeseen, something honest. That is why she values a portable solution that allows her to shoot with precision, power and speed regardless of where her creative impulses take her.

“I love the idea of a professional flash with TTL," she says. "Anything that makes my job easier is a good thing. It means I can focus on what really matters: the creative part.”


There are many flashes out there that can be placed off-camera. But there is only one B1 off-camera flash. No other flash will make it as easy to take the flash off your camera, while at the same time providing you with such creative freedom.

Attach the Air Remote TTL to your camera’s hot shoe to merge camera and flash into one. Then point and shoot, and the B1 will automatically adjust its light output to provide you with the perfect exposure. It is as easy as it sounds.


The B1 is powered by an exchangeable, high-capacity battery that is integrated with the flash. Combine that with an Air Remote TTL and experience the freedom that comes with shooting without power cables or sync cords.

Ten times as powerful as the average speedlight, the B1 enables you to overpower the sun on a sunny day as well as light up larger backgrounds and areas. Having that much power also allows you to add Light Shaping Tools to create a beautiful, soft light even in bright conditions.


At lower power settings the B1 will blast away up to twenty flashes per second. But speed also equals short flash duration. In other words, the B1 will provide a much shorter flash duration than a speedlight set to the same output.

Choose from more than 120 Light Shaping Tools and shape the B1’s already beautiful light into almost any light you can imagine. Explore Profoto’s unique Zoom Function and make fine-tune adjustments by simply sliding the tool back and forth on the B1.
