The Godox QS400II High Performance Kit is a comprehensive studio lighting solution for professional photography applications, consisting of two 400Ws flash heads, two adjustable stands, and two softboxes with grids. This complete setup provides photographers with reliable light control for portrait sessions, product photography, and creative lighting scenarios. The flash heads feature a powerful 400Ws output with precise power control across 50 levels from 1/32 to full power, allowing for exact control of light intensity. The integrated 2.4G Wireless X-System enables remote triggering and power adjustment via compatible transmitters, enhancing workflow efficiency both in the studio and on location shoots. Fast recycling times between 0.3 and 1.5 seconds support quick shooting sequences, while flash durations of 1/2000 to 1/800 of a second effectively freeze motion. Each flash comes with a 150W modeling lamp to preview lighting effects before shooting. The included softboxes utilize the Bowens mount system for universal compatibility and provide even light diffusion to minimize harsh shadows. Grid attachments allow for precise light control by limiting stray light, which is especially beneficial in tight spaces. The adjustable stands offer stable support with height adjustability for various shooting angles and setups. This professional lighting kit delivers consistent performance and build quality for demanding photographic environments where reliability and precise light control are essential.
