It will be interesting to see how they preform in what they call HS mode. The long burn suggests that they may have engineered the capacitor(s) to create a flatter than normal luminosity curve. I am taking on faith that their t05 reference means t.05 which means 95% of the capacitor energy has been used by the tube. If they mean t.5 (50%) then its a REALLY long burn.
Their pack approach is interesting as well. I'm planning to get the Godox extension cable for the AD600 which creates the same sort of configuration.
I looked at the video describing how they have implemented masking sequential exposing. Interesting implementation making Group D the means for accomplishing it. That suggests that there are effectively only 3 groups available for "normal" lighting.
I do think the trigger based implementation is easier. Godox using UNITS/ALT feature on the light offers more useful scenarios but doe take more work to setup since it requires going into the menu of each light.
I thought I saw a frosted dome in one of the product pix. That would be similar to the Profoto lights with the sunken tube. Generally, I'd rather change the adapter ring on the modifier than use the mount adapter approach. That does mean certain modifiers are unavailable though.
