The modelling light is actually just what the name says: a modelling light. The brightness of the Godox Wistro Ad600 Pro TTL can be scaled, but the colour temperature is preset. At a certain brightness, the flash's internal fan switches on, which is not really quiet. I recommend an LED video light. There's also one from Godox, it's good quality, but not available at Digitec so far. An alternative might be Walimex.
