The Godox AD400PRO TTL 400W pocket flash is characterised by high flash stability and repeatability across the entire power range. In situations where excellent precision together with uniform light is required, the colour priority mode (Colour Mode) can be activated. In this mode the flash will maintain a tolerance of +/- 75 K regardless of the power setting. Furthermore, this flash can emit a long series of flashes regardless of the set mode and recharges in a very short time. After full power flash output the AD400Pro TTL is ready for the next shot in less than 1 second. For this reason the flash duration is also short. This flash is great for freezing images of fast moving subjects. The minimum flash duration of the AD400Pro TTL is only 1/12340s of a second (for T0.1 at 1/256 power).

The flash has been fitted with a new bulb that allows the use of all available modifiers. The bulb has been fitted with an outer glass cap to protect it from accidental damage. The front of the bulb cap is made of translucent glass for uniform light diffusion. The bulb can be replaced without the use of additional tools. In addition, it has been equipped with an LED modeling lamp with a maximum output of 38 W (equivalent to the output of a 500 W halogen lamp). The modeling light can be set manually or operate in proportion to the flash power setting.

The flash body is made of high-quality synthetic material. The large LCD screen of this flash is easy to read even in bright ambient lighting conditions. As for the attachment for the light modifiers and the stand holder, both are made of metal to ensure a high strength of the whole. In addition, the stand mount with infinitely adjustable flash tilt is robust enough to support even very large softboxes (up to 120 cm). Equipped with an attachment for Godox light modifiers, but thanks to the included adapter you can also use accessories with a Bowens attachment, which guarantees compatibility with a wide range of modifiers available on the market.
