For a nice crisp blue color the hami 250 14k is the only bulb i could fine that i liked. It is a very nice color, decent par and a pretty good price. That was the only blueish bulb that would fire up with that ballast. I don't know if the 20k xm will fire with it or not, but there par sux anyhow. HTH
