Profoto B20 Duo Kit
Compact, robust and lightweight battery-powered monolight
The Profoto B20 builds on everything that made the B10 range an industry standard, but with faster performance, a more powerful LED, and greater versatility. Designed for photographers who demand reliability in any environment, these flashes are designed to handle a wide variety of conditions with a rugged, rubberized surface that ensures a secure grip and durability for even the heaviest modifiers.
With a 13% faster recycling time than the B10Xs’, you’ll never miss a crucial moment. The new user-replaceable flash tube allows for quick swaps on set, keeping your workflow uninterrupted. The 11 stop power range gives you unmatched creative flexibility, from subtle fill light to full-power illumination. The three flash modes let you adapt to any situation: ECO mode for extended equipment lifespan, Boost mode for extra power when needed, and Freeze mode for the shortest flash duration to eliminate motion blur when capturing the action.
At 40W, the built-in bi-color LED has been enhanced with 50% more output than the B10Xs’, making the B20 even more effective for combining stills and video. With Profoto’s renowned Light Shaping System, you have over 120 modifiers and accessories to turn your creative vision into reality. The B20 features the renowned and intuitive Profoto UI, which practically eliminates dealing with cumbersome technical settings.
Every Profoto product is crafted with premium components and meticulous attention to detail, ensuring that your gear always performs and delivers beautiful light at a consistent color temperature shot after shot. With unmatched reliability, speed, and precision, the B20 is made to work as hard as you are.
