Ideal for on-location photography, the Profoto B1X sets the benchmark once again for cordless, battery-powered monolights. And with both TTL and HSS available, you’re guaranteed the best light shaping experience possible on location, anywhere. It’s power in all the right places.
The B1X is a fully cordless light with simple, intuitive controls and a large easy-to-read LED display. So instead of tripping over cables or fiddling with sub menus or user manuals, you can focus on being creative.
Capture the Moment With AirTTL
Finding the right exposureEXPOSUREExposure is controlled by three elements: Aperture, Shutter Speed and ISO. Achieving the correct exposure is similar to collecting rain in a bucket, up to an optimum level. The rate of rainfall is out of your control (light), yet you can control these three factors: the bucket’s width (lens aperture), the duration you leave it in the rain (shutter speed), and how effective your bucket is in collecting rain (ISO). These three elements work together to control the amount of light per unit area, preventing underexposure (too dark) or overexposure (too bright), giving you a natural looking image. the first time can be a challenge when time is limited or the light is constantly changing. AirTTL automatically does it all for you, just point and shoot.
Shape Light in Broad Daylight with HSS
No matter how bright the sun shines, Profoto High-Speed Sync (HSS) enables you to use your flash at shutter speedSHUTTER SPEEDAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Shutter speed is the length of time that a single frame is exposed for, more specifically how fast the shutter opens and closes to permit light entering the lens, to reach the sensor. A slow shutter speed means a longer exposure time useful for motion blur like the silky look of flowing water, whereas a fast shutter speed means a shorter exposure time useful for freezing the appearance of motion in images like a hummingbird in flight. It is measured in seconds starting at 1 second and halving our doubling in time.
For example: 1/2s, 1/4s and 1/8s are all fractions of a second with 1/2s being the longest exposure time, 1/4s half of that and 1/8s another half etc.s up to 1/8000s. Overpower the sun and shape your light even with large apertureAPERTUREAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Aperture refers to an opening inside the lens, similar to the iris of your eye, that changes in diameter to control the amount of light that enters a camera. Aperture is expressed in f-stops: the lower the number, the larger the aperture, e.g. f/1.4 is larger than f/8. A larger (or wider) aperture allows more light to pass through the lens to the sensor (film) as a picture is taken, particularly useful in low-light conditions. A larger aperture also produces a shallower depth-of-field, and thus more background blur.s in broad daylight.
Battery Power You Can Rely On 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.
Modelling Light with Power & Quality
A powerful LED modelling light enables you to preview your shot and evaluate how light and shadows fall on the subject. It is also useful as main or fill light in low light situations.

Specifications in a Nutshell
Max energy: 500 Ws
Energy range: 9 f-stopF-STOPA notation used to indicate aperture, referring to the ratio between the diameter of the aperture in a lens and the lens's focal length. It is expressed using standard sequence fractional stops: f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, and f/22. The lower the f-stop number, the wider the lens opening (aperture). These numbers might seem arbitrary, but they indicate the focal ratio is at doubles or halves. For example, on a 50mm lens with 25mm aperture diameter, the ratio between the focal length and the aperture is 50/25=2. The f-stop would then be expressed as f/2.s (2.0-10)

The B1X vs the B1 – what’s new?
More power for long location shoots. A new battery with 50% more capacity but same size and weight as the B1 battery. The new battery is fully cross-compatible with the existing B1 battery.
More and better continuous light. A new modelling light LED adds 80% more light output and improves colour rendering from 80 to >90. For use as a modelling light, main light or video light.
More power to shape light in any ambient light conditions. Full 2.0-10 (9 f-stops) HSS power range (the extended HSS power range comes with a free firmware update that also benefits existing B1 users).
More power to lock the stand adapter. A new knob makes it easier to lock the stand adapter with less force.
A slightly updated look:
New black front ring and umbrella tube.
New font on zoom scale.
New print on the back panel.
