Small Led light

[fragginglife]

So I'm looking for a small Led light for a 4 gallon cube i want to set up. Anyone have experience with lighting a tank this small to support sps? I don't necessarily need it to be cheep if a nicer light really will be better but would prefer not to pay more if there is no need. In other words I Don't want to pay a bunch extra for a few cool features to play around with. Also, yes I know sps in a tank this small will be challenging. This is one of the reasons I'm willing to dish out some dough if a nicer light is needed.
