You won't believe the options you have. In fact, lighting is one area that I have trouble keeping up with..........sorry about ending a sentence with a preposition.........!
You need to measure the allowable distance between the ceiling and the floor "and" the floor joists "and" all the other stuff that is under your house. You then need to buy fixtures that will not interfere with those measurements (altho there are surface mounted fixtures that can be attached to the underside of the ceiling if you have a high ceiling). Then, if you are fortunate enough to live in a "metropolitan" area with a great lighting supply house, go there and enjoy. You can create an amazing number of environments with lighting. There are tons of fixtures that utilize all types of light sources. At the supply houses, they usually have the light set up so you can see how it looks. Just depends on what you want and the budget.
If you live close to a lighting center, I highly recommend that you go look.
