Lighting question for the inexperienced

[JTrigger]

I was reading about 250w 20k radiums and saw a note on one of the vendors' websites stating that for these bulbs you need HQI ballasts, Icecap electronic ballsts, or pulse ballasts. I think I have standard PFO ballasts.. so is it safe to assume I couldn't use this bulb or do they make more than one type of radium bulb out there?
