It all depends on what you want to keep? Fish Only or a Reef. If it's for fish only then the lights that come with the tank will be fine. If you want a Reef then you need to decide what type of corals you want to keep. Soft, LPS, SPS, Clams etc.
For soft and some lps corals you can use Power Compacts and if you want to be able to keep everything then MHs are the way to go.
Just realise that you won't be able to keep alot in a 10 gallon tank. The 1"/5 Gallon rule only gives you 2" of adult size fish.
Hope that helps.
