400 Ws & 1/8000 s HSS

Ultra-Fast Freeze Mode

The AD400ProII can freeze even the quickest motions with an ultra-short flash duration of up to 1/27770 second (t0.1). This lets you capture razor-sharp images of flying water droplets, speeding vehicles, or any fast-moving subject. Coupled with a lightning-fast recycle time (as quick as 0.01 s), the AD400Pro II keeps pace with your creativity without missing a beat.

1/512 Fine Power Control

AD400ProII offers 10 power settings from 1/512 to full power, allowing pinpoint adjustment of flash output for consistent, repeatable exposures.

30 W Bi-Color Modeling Lamp

The built-in 30 W bi-color LED offers Constant mode for manual brightness (10 %–100 %) and color temperature (2800 K–6000 K), plus Prop mode, where brightness follows flash output. Stable, flicker-free illumination also doubles as a continuous video light.

2.4 GHz Wireless X System

Equipped with Godox’s 2.4 GHz Wireless X system, the AD400ProII ensures fast and stable multi-light communication. With the X3 trigger, one-tap sync connects all units instantly—no manual group or channel setup needed. It also works seamlessly with Xpro II, X2T, X1, and other X-series transmitters. For expanded triggering options, the USB-C port supports the optional FR433 433 MHz receiver.

Group Indicator Lights

16 distinct lights assign each group a unique color, so you can identify and adjust any unit at a glance—even in low light or from a distance. Just select the group’s color on screen and tweak power or sync settings instantly, keeping your shoot running smoothly.

Intuitive Color Display & Controls

Adjust settings instantly using the bright, full-color TFT display, where all key functions are laid out clearly and intuitively. A single press-and-hold of the modeling-lamp button toggles the lamp on or off, putting control at your fingertips and speeding up your workflow.

Universal Modifier Compatibility

The AD400ProII features both a Godox mount and an included Bowens adapter. Swap between them to use a wider range of modifiers from either ecosystem, unlocking more creative versatility.
*Bowens adapter installs without blocking the Godox mount.

Extension Head for Flexible Lighting

Pair with the optional H400P extension head (sold separately) and 2 m extension cable to position your light exactly where you need it—low to the ground, overhead, or hidden off-camera. The lightweight head clamps or hangs easily, unlocking new creative angles on location.

Fast, Versatile Charging

Connect to the built-in AC400 power input (using the optional AC400 adapter) for uninterrupted AC power. For rapid battery recharge, use the optional Godox UC46 USB charger to top up in just 1.5 hours. *The UC46 can charge batteries for the AD600ProII, AD400ProII, and AD600 series simultaneously.
