i have 400watt icecap with rad. 20k right now, but i'm kinda thinking if the xm20k would give higher par or so. If anyone have experience with these 2 bulbs on icecap 400watt, plz share . thankx !

No way. The Radium is by far the better bulb colour AND PAR wise.

I tested both on 250 watts and radium i do agree is much nicer looking and has higher par

I use HQI ballast
