Profoto B20 Single

Professional Location Photography Made Simple

The Profoto B20 Single solves the critical challenge every location photographer faces: achieving consistent, professional studio-quality lighting without being tethered to power outlets. When shooting weddings, portraits, or commercial work on location, photographers struggle with unreliable speedlights, slow recycle times, and inconsistent light output that can ruin crucial shots.

This 250Ws battery-powered monolight delivers the reliability and power control that professionals demand. The B20 features three specialized flash modes:

• Eco mode: Extended equipment lifespan and longer shooting sessions

• Boost mode: Maximum power when lighting large groups or competing with bright ambient light

• Freeze mode: Ultra-short flash durations up to 1/38,100s for capturing fast-moving subjects without motion blur
