Well, hope you're not replacing with odyssey bulbs... without new (different brand) ballast, you won't be getting the best out of your bulbs...that being said what color from white to 'blue' are you looking for ? If you've seen a tank you liked, you should ask what bulbs are on it.

I'm no expert on bulb/ballast combos...hopefully someone who is, (&/or a vendor), will chime in. Certain bulbs burn better with certain ballast. 20K will be the bluest color. Info on tank dimensions, and type corals held, will help with the advice.
