The QT400ii redefines what a studio strobe can be. Huge advancements in strobe technology make this our flagship plugin studio strobe.
Top of the Line
The QT400ii offers an amazing feature set at an incredible price. It has more features than strobes 5x its price and is backed by the Strobepro 2-Year warranty.
High Speed Sync (HSS)
HSS unlocks your whole shutter speed range where you'd otherwise be limited to your flash sync speed. Practically speaking, you can turn any space into a blacked-out studio by regaining the ability to control your ambient light with your shutter speed.
Built-in X Receiver
The built-in 2.4G wireless receiver means the QT400ii is fully compatible with all Godox/Strobepro X-Series radio controllers. All you need is a controller for full power control and triggering on this strobe.
You're backed by Strobepro's famous customer service and a 2-year warranty serviced right from our store in Calgary, Alberta.
Freeze Motion Easily
Thanks to HSS, the QT400ii can freeze motion even in bright competing light. In a more controlled environment, freeze motion with the ultra-fast flash durations at the QT400ii's lower power settings. Quick recycle times at the mid to low powers can easily keep up with even the fastest burst modes.
Short Flash Duration
The t0.1 flash duration is 1/316s at full power to a blazing fast 1/35086s at minimum power.
8 Stops of Power Adjustment
The QT400ii can dial all the way down to 1/128 power in 1/3 or 1/10 increments (8 full stops). This means you can dial low enough to use your fastest lenses for silky smooth bokeh. Great for portrait and newborn shooting.
Huge LCD Screen
Easily see all your settings on the bright backlit LCD screen.

These lights (XPRO 600) have opened the doors to new lighting options that I didn't have with my previous lights (Alien Bees).
The fast T1 times allows me to freeze action shots with no motion blur. The HSS allows me to shoot wide open at f1.2 to get super shallow depth of field for portraits. The Bowens mount is great (lots of softboxes available for this mount). Definitely a worth-while upgrade!
