good 20k 250w DE bulb..

i have tried the 20k ushio and xm and IMO i think XM is better :D plus i have an electronic ballast from icecap to run those bulbs and my ushio kept flickering...
 
I am running a 20k Radium and by far its one of the best bulb's that i have tried. Recently got super banging color's from the 20k mh my favorite. definitely worth 90 dollars -_-''
