Godox AD600BM Witstro Manual All-In-One Outdoor Flash

The Godox AD600BM Witstro Manual All-In-One Outdoor Flash is a powerful, portable battery-powered monolight, essentially a manual version of the AD600 and AD600Pro for photographers who don’t require TTL metering. Its lithium-ion battery pack and Bowens-mount front make it a genuinely portable, accessory-compatible flash well suited to location and outdoor portrait work.

At 600Ws of power, the flash delivers a guide number of 285 ft. (87m) at ISO 100 with the included AD-R6/R7 standard reflector, with output adjustable across 9 steps from full power (1/1) down to 1/256. Flash duration ranges from 1/220 to 1/10,000 second, and color temperature holds steady at 5600K (±200K) regardless of the selected power level. High-speed sync is supported at shutter speeds up to 1/8000 second for controlling background light intensity, along with first- and second-curtain sync modes and stroboscopic (Multi) flash capability, firing up to 100 times at up to 100Hz.

A built-in 2.4GHz X wireless system functions as a slave receiver, offering wireless triggering and power control at distances up to 262 ft. (80m) across 32 channels and 5 controllable groups (A-E) with a compatible Godox transmitter, and the flash can also operate as an optical slave using S1 or S2 modes. A dot-matrix LCD display provides clear on-board control of all settings, and a 10W LED modeling lamp helps preview lighting direction before firing. A 3.5mm sync cord slot, wireless control port, and USB port for firmware upgrades round out the connectivity options.

Power comes from an included 11.1V, 8700mAh lithium-ion battery pack, rated for up to 500 full-power flashes with a recycle time of approximately 0.01 to 2.5 seconds; the flash can alternatively run on AC power with an optional adapter when portability isn’t a concern. Build quality includes a Bowens-type front accessory mount, compatible with Godox light-shaping accessories as well as modifiers from other manufacturers using the same mount standard, along with built-in fan cooling and an auto power-off function after approximately 60 minutes of inactivity. The flash head (with battery, without flash tube or reflector) weighs approximately 5.86 lb (2.66kg) and measures approximately 8.6 x 9.6 x 4.9 in. (22 x 24.5 x 12.5cm).
