there is a PFO dual 250w ballast and a PFO HQI dual 250w ballast. You can use a HQI ballast on mogul bulbs but it will over drive them. I am using the PFO HQI ballast on 10k bulbs and it makes them more white.
You can tell what ballast you have by looking at the label and looking at where the CHECK mark is on the label. You probably bought the regular one unless you specified the HQI ballast.
