Godox QT400 QT-400 professional high-speed studio flash

Description

Selling my Godox QT-400 professional high-speed studio flashes cause I want to downsize my studio.
The flash is in working condition and looks like new.
It's only been used rarely in a handful of shoots, I'm guessing less than 500 flashes have been fired.
It comes with LED modeling lights and wireless XTR16 receiver for Godox X-System.
It also comes with a protector for the light and their original box [see last picture].
Features:
Can be compared to Flashpoint Rapid 400
Very quick recycling time of just 0.05 sec. to 1.2 sec.
Short flash duration 1/5000 to 1/800 sec.
High color stability +/- 100K
Guide number: 65
The flash works with European voltage
AC220V/50Hz
and comes with European AC cables.
In order to use them in the US you need a step-up voltage converter made for 400 watts [~].
I can include the adapter if you send me this additional amount. A reflector is not included.
