Yamaha PW system can't accept most of the M99 series. (M99 Pro or M99 Pure+) and it will take only M99 Pure which puts out only 500 lumens.
The new PW-X system can't even accept the M99 Pure. So, the latest 2017 systems can't accept any of the M99 series.
I have confirmed this with Supernova. The Yamaha system is not designed for such high power draw.
Your solution would be to try smaller lights like Supernova V521S or V6S.
What was the Nominal wattage the PW-X light output can take?
