one thing to add to this the 250 watt radium will look horable as it will not light on a regular PFO ballast. unlike the 400 watt radium the 250 watt radium doesnot have a starter built in to it.
also Ushio, BLV and AB will not look as good as they will on a HQI as the HQI is the proper ballast for the 250 wat versions of these bulbs.

Steve, the 400w Radium doesn't have a starter. It is started from the ballast.

the 400 watt radium has a probe inside it so a ballast with out a started will start it.. the 250 watt doesent so you need a starter on the ballast or it stays black.
