Profoto B20 OCF Flash Head

The Ultimate Portable Monolight for Creators on the Move

Building upon the massive success of the legendary B10 series, the Profoto B20 represents the next generation of highly portable, battery-powered monolights. Engineered for wedding, location portrait, and hybrid commercial photographers, this single head provides a robust 250Ws of lighting power in a form factor roughly the size and shape of a large camera lens.

Whether you are balancing exposure against a bright sky, freezing rapid movement on a windy shoot, or seamlessly blending continuous light for a video project, the B20 is a versatile cornerstone for any modern lighting kit. It delivers an industry-leading 11-stop power range and blistering recycling times that ensure you are never caught waiting for your gear to catch up.

Why You'll Love This Flash

• Blazing Fast Performance: The B20 dramatically cuts down on waiting. With a recycling time of just 0.01 to 1.2 seconds, you can confidently shoot in fast-paced environments like fashion runways or wedding dance floors without worrying about dropped frames or missed flashes.

• Upgraded Bi-Color LED: Hybrid shooters will appreciate this massive upgrade. The built-in 40W continuous LED is 50% brighter than previous models, putting out a staggering 5,000 lumens (1,700 lux bare bulb). Because it is fully bi-color (2800–7000K) with a high CRI of 94+, it serves as a highly capable continuous video light that perfectly matches your ambient environment.

• Three Intelligent Flash Modes: You have total control over how the strobe performs. Use Eco Mode to extend battery life and reduce thermal load on long shoot days, Boost Mode when you need maximum raw power, or Freeze Mode to achieve incredibly short flash durations (up to 1/38,100s) to completely eliminate motion blur.

• Built for Real-World Abuse: The exterior features a rugged, rubberized surface that gives you a secure grip and durability for mounting heavy modifiers. It also introduces user-replaceable flash tubes, meaning if a bulb breaks on set, you can quickly swap it out instantly without sending the unit in for lengthy service. A dedicated 3.5mm sync port has also returned for wired triggering.

• AirX Connectivity: With built-in Bluetooth AirX, you can trigger the flash perfectly from your smartphone camera or control all your settings visually through the Profoto Control app.

Technical Specifications

Things to Note

Because the B20 belongs to the battery-powered OCF (Off-Camera Flash) family, its flat glass front is specifically designed to safely accept Profoto's lightweight OCF modifiers. While the new rubberized grip handles heavy modifiers better than previous generations, you should still take care when balancing large, heavy traditional softboxes on lightweight location stands (and consider the separately sold optional OCF handle for better leverage).

Additionally, this strobe relies entirely on its proprietary rechargeable lithium-ion battery. It cannot be powered directly via AC wall power if the battery is completely removed or depleted. If you frequently shoot high-volume, all-day sessions, it is highly recommended to purchase an extra battery to swap out while your depleted battery is charging.
