If you are going to do a REAL S.A. tank, you will need almost saltwater level lighting.
The reason is that you may want to actually SEE your fish. S.A. water is very dark, tea colored, because the water is saturated with tanins (an acid released from driftwood in the water and rotting leaves)
You actually SHOULD do this, most people complain about how finicky angels, discus, and other S.A. cichlids are (including Oscars with things like HITH) The reason is because these fish have very little ummune systems, because they don't need one in their natural enviroment, the tanins kill off almost all bacteria and fungus in the water, so the fish don't actually have to fight off any of these things.
I had a S.A. tank, it nis still set up the same, but stocking is from around the world now. The water gets very dark and with teh stock ligthing, I could barely see my fish, I now run 2 4' T5 lights and is barely did the trick. This is another reason that the S.A. fish tend to have such bright and flashy colors, because otherwise they are utterly invisible in the water, which does not hlep out much in mating.
(Sorry, I am not tryin to sound like an insufferable no-it-all, just pointing out that Discus and Angels are not as finicky as some people say, just as long as the tank is set up how their natural enviro is, which, is what you are asking about is lighting for that enviro.)
