Power and portability

The Profoto B20 is a 250W off-camera flash head built for photographers who need studio-grade output in a compact form. It suits portrait, event and on-location work where consistent illumination and reliable recycling are essential.

Recycle speed and colour

The unit recycles in 0.01 to 1.2 seconds and holds a stable 6000K colour temperature within ±100K in both Eco and Boost modes. Freeze mode delivers a flash duration as short as 1/11700 s (t0.1) for crisp capture of fast-moving subjects.

Mounting and maintenance

A dedicated 3.5 mm sync port allows direct integration with standard studio triggers. The flash tube is user-exchangeable so a spare can be swapped on-site without tools. Photographers who need built-in wireless radio control or battery-only operation will need a different system.
