Yes, that would be enough for Soft corals and most
LPS..
The
LED's do have some good benefits, but are almost too much light for softies, and it takes some dedicated acclimation for even
LPS. If not thinking
SPS, then I would suggest the T5's. One thing to consider with T5's though is, bulbs need to be replaced yearly. They change wavelength over time and old bulbs start to help algae growth, not corals. Just something to keep in mind down the road.
Good luck!
