New Icecap ballasts and radiums

[celebrityovernight]

Hey guys,
I was wondering if the newer 400watt mh ballasts from Icecap would fire the radiums at the right spec. I'm debating whether I should go with 20k xms or 20k radium. Any input is appreciated.

Well since the radium 400 watt bulb is more like 360 watts they tend to be over driven on a 400 watt ballast. I think they would be ok though.
