Godox QS400II Studio Flash Head

The Godox QS series includes a host of power options, ranging from 300Ws to 1200Ws. A defining feature is its capability to regulate flash energy across 5 exposure levels (1/1 - 1/32), with a precision of 0.1 EV. Additionally, the series boasts of a rapid recycle time of less than 1.5 seconds when charged to full flash energy.

Remarkably, at its minimum power, it can accomplish a concise flash duration of only 1/2000s (t = 0.1), providing the flexibility to shoot continuously during a session. Its flash color temperature is constant at 5600K, but can vary within a tolerance of ± 200K depending on the set flash energy.
