The versatile AD400Pro II is the perfect flash companion for professionals and beginner photographers working in studios or outdoors. It offers 400Ws with 10 steps of output, ranging from 1/1 to 1/512 in 0.1 increments. The flash's detachable lithium battery pack provides up to 460 full-power flashes, a higher number than the previous AD400Pro. The II version also features a high-speed sync mode that works with shutter speeds up to 1/8000 sec, introducing a convenient freeze mode with flash durations from 1/3470 to 1/27,770 sec for stopping action. Outside of the freeze mode, the AD400Pro II has normal flash durations from 1/230 to 1/16,120 sec.

Flash functionality can not only be made onboard, but also wirelessly via the head's built-in Godox wireless X system with a range of 328', featuring 16 groups, 32 channels, and 99 IDs. Remote operation requires a separately purchase of trigger. The AD400Pro II is fully compatible with the separately available XPro, XPro II, X2, and X3 models, while a 3.5mm sync port provides a wired sync triggering mode. Although the AD400Pro II is equipped with a 2.4 GHz wireless receiver, it also works with 433 MHz signals by connecting the separately available Godox FR433 via a USB-C port.

Just as other popular Godox units, such as the advanced AD600Pro II and the AD200Pro II, the AD400Pro II provides group color functionality. This means that each of the 16 groups will display a different color locally on the flash head for easy group identification even from a distance. Godox has improved the physical body of this flash, bringing a more elegant and modern design that enables intuitive local operation. In addition to the group color capability right at the head of the flash, the AD400Pro II body also has a 2.4" color screen and a handy rotatable select dial.

The flash comes with a 21.6V/2600mAh lithium battery pack that provides up to 460 full-power flashes in outdoor situations and location shooting. Other features include integrated battery level indicators and and power-saving auto-off functionality. Godox conveniently includes the detachable battery, the charger, and the power cord in the box. A carry bag is also supplied to add to the flash's portability.

Another setting that Godox maintains from the previous flash version is its stable color temperature mode, which tightly controls color to keep temperature changes within +/-75K across the entire power range. With a flash tube at 5800K (+/-200K), the AD400Pro II works great for both studio and location photography and is well-suited for portraits, products, weddings, and other types of shots.

The AD400Pro II's 30W LED modeling light is adjustable from a wide 2800 to 6000K CCT with variable brightness from 10 to 100%. You can also set the modeling lamp to a PROP mode that allows the CCT and brightness level settings to follow the flash power.

• OFF, FREE, and PROP modes.
• High CRI/TLCI ratings of 97/98.
• You can have it as an alternative light for video recording.

The head has a proprietary Godox mount, but includes a widely compatible Bowens mount adapter to expand your possibilities when it comes to optional modifiers. Godox also offers optional Broncolor, Profoto, and Elinchrom mount adapters if needed. The flash is compatible with a wide range of optional umbrellas thanks to its integrated umbrella hole, as well as with softboxes in different shapes and various light stands.
