Andrew.. I run the 250W Iwasaki on a PFO.

Looks great IMO. Very crisp with actinic supplementation. As well you get all the PAR of the Iwasaki for growth. I'd recommend it to anyone.

FYI,
There won't be a difference between a dual PFO and a single PFO ballast. All they do is put a second ballast inside the case.
