Question about Walimex Wt-806

I would recommend the Bowens S2 adapter from Godox. This is where the flash is clamped. Godox S2 System Flash Adapter Bowens Mount (Bracket)

Can this tripod be used with Walimex ring light 40 W.?

Does is come with a ballhead ? I want to use it to mount the HTC Vive base stations, but they need to have a 45° angle.

There is a solution from Walimex itself. Just google "Walimex Universal flash shoe".
