You dont need a Shield.
PFO HQI said that because typically when you use these ballasts they are for DE bulbs. BUt you don't need a shield with a SE bulb |

"i just got a se 400w radium bulb to be run on a pfo hqi ballast"
Say hello to a glorious short bulb life! You REALLY might want to consider a M135 or 155 ballast for the radiums... they arent HQI rated, not even 400 watt bulbs technically (360's). Either that, or use Aquaconnects.
