The Godox SK400III-V is a 400Ws studio flash monolight, the upgraded Version III evolution of the popular Godox SK400II, featuring a modernized body design, refined control interface, and more precise power adjustment. It’s designed for portrait, product, e-commerce, fashion, and commercial photographers who want dependable, consistent output in a compact, easy-to-use studio strobe.
The unit offers 400Ws of power with a guide number of 213′, delivering bright, consistent output for small to medium studio scenes. Power is variable from 1/32 to 1/1, with fine adjustment in 0.1-stop increments for precise, repeatable exposure control across a full 6-stop power range. Flash color temperature is rated at 5700K (±200K), with a 0.1 to 1.5 second recycling time and flash durations as short as 1/260 second, keeping shot-to-shot consistency reliable during a session. A 3-second auto-memory function preserves the last-used settings, helping keep workflow moving smoothly between pauses.
A 10W LED modeling lamp, replacing the halogen bulb used in earlier SK-series models, offers 5-100% adjustable brightness for previewing lighting direction and quality before firing, and can be set to operate proportionally to flash output, independently, or turn off automatically during the flash itself. Triggering options are flexible, including a sync cord, optical slave triggering, a manual test button, and Godox’s built-in 2.4GHz X Wireless System, which supports remote power control, group and channel selection (16 groups across 32 channels), and full compatibility with Godox X-series transmitters such as the XPro, X2, and X3 for multi-light setups.
Build quality includes a redesigned rear LCD panel for clear visibility and intuitive adjustment of power output, modeling lamp brightness, and wireless settings. The unit is built around the industry-standard Bowens S-type mount, giving it broad compatibility with softboxes, umbrellas, beauty dishes, reflectors, snoots, and grids from Godox and third-party manufacturers. Weighing only about 5 lb, the SK400III-V is lightweight and easy to reposition around a studio, and it runs on standard AC mains power (110-120VAC).
