XM bulbs

[sandman12]

I just got my MH running and have 2-400w 10k XM bulbs. One is burning white and the other an ugle yellow. IS the yellow one just getting broken in or is it broken?

Has one of the bubs been replaced recently? They take a couple of weeks to break in. After that they become their true color. My XM 20,000K's have broken in and changed color pretty significantly.
