Rent NowThe Godox AD400Pro Witstro is a portable, battery-powered monolight built for photographers who need studio-quality output in outdoor and on-location settings without being tethered to AC power. Part of Godox’s professional AD-Pro series, it combines strong flash power with TTL automation and high-speed sync in a compact, lightweight housing, making it a popular choice among wedding, portrait, and commercial photographers who shoot away from the studio.
At the core of the AD400Pro is 400Ws of flash power with nine adjustable power levels ranging from 1/256 to full power (1/1), and a guide number of approximately 72m at ISO 100 with the included high-efficiency standard reflector. The unit supports both TTL and manual exposure modes, along with high-speed sync up to 1/8000 second, allowing wide-aperture shooting even in bright ambient light. A Stable Color Temperature mode tightly controls color shift, limiting variation to within ±75K across the entire power range, particularly useful when adjusting power on the fly during a shoot, while flash duration ranges from 1/240 to 1/12,820 second.
Wireless control is handled through Godox’s built-in 2.4GHz X System, allowing the flash to be triggered and adjusted remotely from a compatible Godox transmitter mounted on the camera, with an operational range of up to 328′ (100m). The system offers full TTL compatibility across Canon E-TTL II, Nikon i-TTL, Sony, Fujifilm, Olympus, and Panasonic autoflash systems, along with Master and Slave functionality that lets the AD400Pro work in combination with other Godox TTL camera flashes and outdoor flashes. The flash also includes a 30W LED modeling lamp for previewing light direction and quality before firing.
Power comes from a removable 21.6V/2600mAh lithium-ion battery pack rated for up to 390 full-power flashes, with a fast recycle time of 0.01-1 second (capable of 12 continuous flashes at 1/16 power) and automatic power-off after 30-120 minutes of idle operation to conserve battery life. An optional AC power adapter is also available for continuous studio use. The AD400Pro uses a Bowens-style mount (via an included Bowens mount adapter ring), giving it compatibility with a wide range of third-party softboxes, reflectors, and other modifiers.
Build quality centers on a small, lightweight, and portable design measuring 220 x 102 x 128mm and weighing about 2.1kg with the battery installed (flash tube and reflector not included in these measurements), along with a Type-C USB port for firmware upgrades and a 3.5mm sync cord jack for additional triggering methods.
