Great advice Walter,
I used the same site to choose my xm10000k bulb and I am totally pleased with the color.
Richer,
I noticed that that link doesn't tell you who the bulb manufacturer is. I would try to find out because even the same k rated bulbs will look different from different manufacturers. Also, I would check out
www.diyreef.com if I were you. I got a 175W Mh "custom retro" with the bulb, reflector, icecap ballast, two vho actinic bulbs , vho ballast, all wired together with all the brackets and endcaps and shipped to my home for $500.00 (CANADIAN!). I think I still have a discount code that you can use too for $10US off. Just my experience.
