DIY metal halide question

[whaase]

I've bought some 250w, 10000k MH bulbs from Sunaquatics, I was going to buy these ballasts from Brite-Lite:

But then I read this.

So my question is, will the ballasts from Brite-Lite work with these bulbs? And why would color temp make a difference to a ballast?
