Why choose the B1X?

Robust ease of use for professionals

Professionals need straightforward gear they can trust when they need it. And that is exactly what the B1X is. It is a robust, fully cordless light with a large grip friendly handle and a few simple, intuitive controls. So instead of tripping over cables, fiddling with user manuals or worrying about your gear, you can focus on being creative and getting the job done.

The power and speed you need

Whether you’re shooting in bright sun or low light, B1X offers you both power and control with 500Ws adjustable over a 9 f-stop power range. And you’ll never miss that perfect moment. With a speed of up to 20 flashes per second and short flash duration of 1/19,000s, the B1X will always be able to keep up with both the action and your camera.

Battery power you can rely on

Don’t worry about losing power at a vital moment – B1X’s rechargeable Lithium-ion battery provides up to 325 flashes at full power and tens of thousands at lowest power. And it recharges in no time.

Modeling light with power and quality

A powerful LED modeling light enables you to preview your shot and evaluate how light and shadows falls on the subject. The high color rendering of the LED also makes it very useful as main or effect light in low light situations.

Capture the moment in perfect light with AirTTL

Finding the right exposure first time can be a challenge when time is limited or the light is constantly changing. AirTTL automatically finds it for you – so all you need to do is point and shoot. Alternatively, you can switch to manual mode, keep your previous TTL settings and fine tune the exposure until you achieve exactly the look and feel you want.

Shape light in broad daylight with HSS

With Profoto High-Speed Sync (HSS) it doesn’t matter how bright the sun shines. It enables you to use your flash at shutter speeds up to 1/8,000s. So you can overpower the sun and shape your light even with large apertures in broad daylight.

Explore your light shaping potential

Photography is all about controlling and shaping light. With the B1X it’s easy to take your creativity to the next level with any of Profoto´s 120+ light shaping tools.

Power in all the right places Profoto B1X

We’d like to think of the B1X as power with a purpose. And that purpose is simple; we want you to be able to realize your vision wherever you may go. If that’s halfway up a mountain, overpowering the sun hanging off a rock overlooking the Mediterranean – then so be it. Because the B1X is no stay-at-home flash; it’s for the professionals who likes to get out there on location in the real world. That’s why B1X offers Profoto studio light reliability and performance in a cordless and robust and package that is battletested on location by professionals. Because we want you to have power in all the right places.
