Godox H400P Extension Head for Witstro AD400Pro Flash Head (8′)

The Godox H400P Extension Head for Witstro AD400Pro Flash Head (8′) is a compact, lightweight flash head extension that separates the heavy flash body from the actual flash head, giving photographers far more flexibility when positioning light on a boom arm, lightweight stand, or in otherwise hard-to-reach setups. Weighing less than half of the AD400Pro flash itself, it makes it possible to use boom arms and light stands that might not otherwise support the full weight of the strobe.

To use the H400P, the flashtube is simply unplugged from the AD400Pro’s main body and moved into the extension head, then the 8-foot (approximately 2.4m) extension cable is connected to the strobe body via a secure twist-lock connector, functioning as a lightweight go-between with no loss of flash energy or power output. Even with the AD400Pro’s already compact form factor, the smaller H400P head can fit into tighter spaces, offering added versatility for unusual setups such as automobile interiors, macro photography, and small product shoots.

The extension head includes an integrated Godox-style mini reflector mount, letting Witstro light modifiers attach directly, while a separately available Bowens Mount Adapter (BO-AD400PRO) extends compatibility to Bowens S-type modifiers as well. A built-in 30W LED modeling lamp is fully dimmable and fan-cooled, remaining controllable from the main strobe body, and a fully adjustable mount features a free-moving, 220-degree tilt lock along with an integrated umbrella shaft socket for mounting an umbrella directly to the head. A large grip handle aids handheld positioning.

Build quality centers on a durable, compact design intended for reliable use in both studio and on-location settings, weighing approximately 2.5-2.7 lb (1.2kg).
