I replaced my actnics too. They're whiter than the one that came with the unit. And as the title says, I added 150 watt XM 20k bulbs. It's not as blue as I thought, and I am very pleased with the look.
wow..the ballast must really make a huge difference. the 15k XM we have was way bluer than that. it was a 250 watter, but still.....
your tank looks nice, ours looked like straight actinic-

i don't know...bear in mind that the fixture we are using is one of those no-name chinese coralife clones. it could be a crappy ballast...or a real good ballast. i'm thinking crappy ballast.
yes, they are sunlight supply ballasts and lumenarcs..still using chinese bulbs though...12 bucks a piece
plus 440 watts of actinic. the corals look like they would glow in the dark
sig?
