Best MH Bulb Brand?

[zotl]

I'm about to replace my 400w 10000k Blueline Bulb. It has done o.k., but I'm wondering if there is a better brand. It's supplemented by 2 48" Uri VHO actinic 03 and 2 48" Uri VHO actinic white. Would there be any coral growth benefits by going up to a 20000k? Any suggestions on bulb brand?
