You mention HQI and PFO ballasts

When you mention PFO are you referring to the PFO regular Metal Halide ballasts. If I recall correctly they market a HQI ballast for the 400 watt but it is actually a SON AGRO 430 watt HPS ballast.

As fas I know there is no "HQI" ballast for a 400 watt bulb in North America, just the 250 watt
