For years, 'studio power' and 'grab-and-go' were a trade-off: you got the big pack-and-head light or you got the speedlight, never both. The Profoto B10X Plus is the light that closed that gap. It's barely bigger than a 70–200mm lens, runs on a battery, and still puts out 500 watt-seconds — enough to overpower midday sun through a softbox. It's the strobe we hand to people who want one light that does almost everything.
What the B10X Plus is
The B10X Plus is a battery-powered, off-camera monolight in Profoto's compact B10 line — the brighter sibling of the standard B10. The numbers that matter on set:
Profoto B10X Plus — key specs
- Output
- 500Ws
- Power range
- 10 stops, down to low fractions for soft fill
- Flash modes
- TTL + HSS (high-speed sync to 1/8000s)
- Modeling light
- Bright, adjustable LED (usable for video/continuous)
- Power
- Exchangeable Li-ion battery
- Control
- Profoto Air / AirTTL via Air Remote; app control
Two things make it special. First, it's a flash and a continuous light in one — the built-in LED modeling lamp is bright and adjustable enough to use as a video source or to light a behind-the-scenes clip. Second, it speaks Profoto's Air system, so it drops straight into the same TTL/HSS workflow as the rest of the B-series and Pro packs you might add for a bigger build.
Why creators reach for it
It goes where the sun is
High-speed sync lets you shoot wide open at 1/8000s, so you can drop the sky two stops, keep f/1.8 bokeh, and still pop clean light on your subject at noon. For outdoor portraits and on-location brand work, that combination — battery power plus HSS — is the whole reason to own (or rent) one.
TTL gets you the first frame fast
Switch on TTL and the B10X Plus meters the scene and sets a workable exposure on the first shot. Lock it in, flip to manual to keep it consistent, and you've gone from setup to shooting in seconds. On a run-and-gun day with talent waiting, that speed is worth real money.
It scales from one light to a full build
One B10X Plus and a softbox is a complete portrait kit. Our kit ships as two heads with four batteries, a charger, and your choice of Air Remote — so you can run a key-and-rim setup, or a key-fill-background three-light build, all from one trigger. Need more punch for a big group or a bright cyc? Add a pack-and-head system on the same Air channel.
Shaping the light
A bare strobe is a starting point, not a look. The B10X Plus takes Profoto's OCF modifiers, and via adapters reaches the whole modifier wall:
- OCF softbox or octa — soft, wrapping light for flattering portraits and beauty.
- Beauty dish — crisp, punchy light with a fast falloff for fashion and editorial.
- Grid — controls spill so you light the subject and not the background.
- Gels — color the background or warm the key to taste.
When to rent it
The B10X Plus is a genuinely buy-worthy light — but renting still wins when:
- You need a matched pair (or three) for a multi-light build without owning a shelf of strobes.
- The shoot is occasional — a few portrait or product days a year doesn't justify the purchase.
- You want to try the Profoto Air workflow before committing to the ecosystem.
- You're already renting the room — add the light to the studio booking and walk in ready.
Our B10X Plus kit includes two heads, four batteries, a charger, and an Air Remote for your camera system (Canon, Nikon, Sony, Fuji, or Universal). Single heads are available if you just need to add one to an existing build.
