GODOX AD400 Pro II Outdoor Flash

Announced in August 2025, the Godox AD400Pro II is a 400Ws battery-powered outdoor flash designed for location photography, portraiture, fashion, advertising and mobile studio work. The second generation keeps the balance of power and portability that made the original model popular, while adding finer 1/512 power control, a dedicated Freeze mode, a larger bi-colour modelling lamp, colour group indicators and a more modern TFT interface. It also remains fully integrated with the Godox 2.4GHz X wireless system.

400Ws output with precise 1/512 power control

The flash delivers 400Ws at full power and offers ten stops of adjustment from 1/512 to 1/1 in 0.1-stop increments. This makes it easier to fine-tune exposure when balancing flash with ambient light or working with reflective products, portraits and multi-light setups. Godox specifies a guide number of 72 metres at ISO 100 with the efficient reflector, while recycle time ranges from approximately 0.01 to 1 second depending on output.

Freeze mode and high-speed sync for fast action

A dedicated Freeze mode provides flash durations from approximately 1/3470 to 1/27,770 second at t=0.1, allowing the unit to stop very fast movement such as splashes, jumping subjects, sports and other action. High-speed sync is supported up to 1/8000 second, which is especially useful outdoors when shooting with wide apertures in bright daylight. The flash also supports first-curtain, second-curtain and stroboscopic operation, including up to 100 flashes at 100Hz.

Godox X wireless control with 16 colour-coded groups

The built-in 2.4GHz Godox X receiver supports 16 groups, 32 channels and 99 wireless IDs with an operating range of approximately 100 metres. When paired with a compatible transmitter, TTL operation is available for Canon, Nikon, Sony, Olympus / Panasonic, Fujifilm, Leica and Pentax systems. One-tap sync is supported with the Godox X3 trigger, while coloured group indicator lights make it easier to identify individual fixtures in larger multi-light setups.

460 full-power flashes from one battery

The removable 21.6V / 2600mAh lithium-ion battery provides approximately 460 full-power flashes per charge, making the unit well suited to outdoor sessions and locations without mains access. For longer studio use, the optional AC400 adapter can provide continuous AC operation. The optional H400P extension head can also move the flash head away from the main body, which is useful when mounting the source overhead, on a boom or in positions where lower weight at the end of the stand matters.

30W bi-colour modelling light and wide modifier compatibility

The built-in 30W LED modelling lamp offers adjustable colour temperature from 2800K to 6000K and brightness control from 10% to 100%. Godox specifies approximately CRI 97 and TLCI 98. The fixture uses the native Godox accessory mount and can also work with Bowens S-mount modifiers via the adapter, giving access to a broad range of softboxes, reflectors, beauty dishes and other shaping tools for portrait, fashion and commercial photography.
