The B20 OCF Flash Head Duo Kit is designed for creators who need reliable power, fast performance, and flexible lighting control in demanding environments. Built for both photo and video production, it supports quick setup, consistent results, and seamless integration with a full lighting ecosystem.
Fast Recycling and Flash Performance
The B20 delivers a 0.01 to 1.2 second recycling time for capturing fast action with minimal delays. Its freeze mode enables shutter speeds up to 1/38,100 second, helping photographers stop motion with accuracy. The unit supports up to 400 full-power flashes per charge, ensuring efficient shooting during high-volume sessions.
Wide Power Control Range
An 11-stop power range supports precise output adjustments for different lighting conditions. This allows creators to manage exposure easily, whether shooting portraits, action scenes, or controlled studio setups.
Bi-Color LED for Hybrid Workflows
The 40W bi-color modeling lamp provides an improved continuous light option for video recording, live streaming, or mixed photo-video environments. This gives hybrid shooters flexibility when switching between stills and motion.
Multiple Flash Modes for Versatile Use
Boost, Eco, and Freeze modes support different workflow needs. Freeze mode captures fast subjects, Boost enhances output when needed, and Eco optimizes battery life for longer shoots.
Strong On-Location Build
The compact housing and rubberized grip offer a reliable handheld or mounted solution. A user-replaceable flash tube supports quick swaps to maintain workflow continuity on set.
Broad Modifier and Accessory Compatibility
The OCF mount supports over 120 light-shaping tools, enabling photographers to refine light output with precision. It also integrates with AirX connectivity for remote control, TTL, HSS, and multi-light setups.
Core Backpack II for Transport
The included backpack provides organized storage with adjustable dividers, a padded main compartment, a laptop pocket, and weather-resistant fabric. It supports easy transport for on-location work.
Desktop Control App Integration
