The wiring diagram on page 6 of the PDF, shows how to wire two PL lamps.

Many years ago, when power compact lamps were newish, several marine tank supply companies sold fixtures using standard four tube 32 ~40 watt ballasts wired to one PLL socket. Those were considered and sold as 65 watt ballasts. I've opened up a couple to install new waterproof end cap & cord assemblies.
I used some running 55 watt GE 9325 lamps on freshwater tanks. I noticed no difference between them and standard off the shelf 65 watt ballasts running the same lamps. Sorry, but I didn't even know what PAR was then so I've no data.
