I had my PDP's under MH and be prepared to shade them. I found they melted under direct light and really grew good if UI put them under an overhang making them stretch for light.

The radium will be much bluer on on electronic ballast vs a magnetic hqi. Very nice looking bulb but I don't think at it's bluest it will look like 6 blue+ bulbs! That must have been one BLUE tank.
