Strobepro 400M Studio Strobe (Godox QS400 II)

4 reviews

Powerful, affordable, sensible

The 400M is based on the same body design as our XPRO studio strobes. It has many of the same modern conveniences with its built-in radio receiver, and the ability to dump power internally.  The 400M forgoes some bells and whistles for a more attractive price.  There's just so much value crammed into this workhorse of a light!


Not every user requires the high speed sync capability offered by our XPRO strobes.  In fact, HSS has fairly limited applications indoors.  The 400M provides a lower cost option for shooters who are not using this feature.  

Built-in X Receiver

The built-in 2.4G wireless receiver means the 400M 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. 


The 400M is fast and recycles from 0.3 to 1.5 seconds at full power.


The Strobepro 400M flash is built out of metal.  It's designed to be used daily and can take the abuse.


Less expensive strobes can overheat easily.  The 400M is fan cooled with overheat protection.

    Great build quality at a super affordable price pint

    I bought this for a hair light in my studio, and it perfectly compliments my XPRO 600W's and X600 II HHS M's. Same build quality as the XPRO's. Really happy with this.

    Products are Products but Customer Servicee

    Found that the person who helped me was insanely informative and helpful. Went in to buy a light and walked out with a lot more (usually followed by buyers remorse) however, everything purchased has been insanely useful. Would highly recommend people going here as well as I will be returning.
