It depends what kind of money you have. Metal halide is the best, and most expensive. Most people agree that VHO and T5 are second best, but they can be nearly as expensive as halides. The most inexpensive option you can go for (and still keep coral) is compact fluorescent.
The Jebo fixture you describe will give you a nice amount of wattage for the price. The problem is that Jebo has a reputation for shoddy equipment. Just as importantly, they have a reputation for selling their units with cheap bulbs. It becomes a situation where the fixture is decent, but the bulbs are no good. And at $25 a pop, replacing the bulbs ain't cheap.
Personally, I think lighting is something you can afford to delay spending big money on at first. (A nice protein skimmer is much more important.) If compact fluorescent is your budget, I would look at 48" units from Coralife and Orbit USA. Both are better brands than Jebo, and worth the extra money.
Compact fluorescent will allow you to keep some corals. If you find you like it, you can upgrade.
Putting metal halides over a 48" tank is going to cost you at least $450, probably more.
