Depends on what you are buying (for wat watt fixture).
If your fixture takes square pin, i'd look into the sunpaq bulbs. They come with dual day (6500 and 10k) and dual actintic (420 and 470 nm).
Get one of each of those. If not, then yes, the 10k and actintic would work. You could also settle for 2 50/50 (half 10k half actintic) bulbs.
Hope this helps.
