Light bulb change questions

[TWINPEAKS]

Its time to change my M.H. Right now I'm running 3 reeflux 250 watt 12k bulbs.I'm wanting some info on the XM 15k,how blue are they etc.These will be on Ice cap ballasts. Any suggestions on other brands would help also.

I have XM 20ks and they look really white to me on Hamilton magnetics. But everyones eye is different. Tomorrow I will be switching to Lumatek electronics, hopefully they are more blue.

I'm running 3 250 watt on icecaps plus 6 39 watt t-5's.thinking of using a XM 15k on the ends and a 20k in the middle or possibly 10k on the ends.
