Godox Knowled Adjustable diffuser kit AD21 K3

The Godox Knowled AD21 K3 Adjustable Diffuser Kit delivers electronically controlled, motorized diffusion with smooth transitions from hard to ultra-soft light. With dual control modes, flicker-free performance up to 300fps, multiple power options, and broad compatibility via Bluetooth, DMX, and onboard controls, it’s a portable, collapsible solution for precise, on-set lighting refinement.

The Godox Knowled AD21 K3 Adjustable Diffuser Kit is an advanced motorized diffusion system designed for creators who need tight control over light softness without swapping physical modifiers. Its electronically adjustable panel shifts seamlessly from hard to ultra-soft diffusion using two modes: Level Mode for 0–100% visual diffusion control, and Light Reduction Mode offering professional EV adjustments from -0.1 to -2.0 EV. Built with patented frequency adjustment technology, it ensures flicker-free operation across five frequency levels and supports recording at frame rates up to 300fps. The collapsible design keeps the panel compact for transport while allowing fast setup on location. Versatile power options include USB-C, V-mount, or NP-F batteries, delivering up to 20 hours of runtime on a 100Wh power source. Control flexibility is equally broad, supporting a dedicated controller, Bluetooth app, and DMX/RDM. The included AD00-02 controller offers streamlined operation in a lightweight form factor, making the AD21 K3 a highly adaptable tool for professional lighting environments.
