Sorry i might not be much help.

But i run the Radium 250W on HQI ballast and it is by far the best bulb i have used so far

I run 3 400W 20Ks over my 220 and am very pleased with them.

I don't know very many people that have run 400w radiums on an HQI ballast that have been displeased. Bulb life is a little short but the combination is very nice.
