Which UW flash and video/focus-light?

Hi UW photografers and filmers,

I just have acquired an Olympus OMD-5-MII in Nauticam housing . I need now flash(es) and light(s) for video (and also light for focus) and search for an optimal solution. Are here divers out that have experience with the Symbiosis SS-2 hybrid-system who can report how this performs on the longer term use?

Or is it better to have flash(es) and video light(s) separately?

Thank you for advice and/or opinions, Wolfgang

As can be seen from the prospect of the symbiosis SS-2, the video ligth can be disassembled from the flash. Does anyone know whether it is possible to operate BOTH video ligth AND flash separately UW?

Wolfgang
