Led lighting questions

I have two 48" current orbit led setups 96x.5w led on each which gives me 96 total watts on my 150 gallon tank. Tank demensions are 48x24x30. I want to get into more sps corals. Right now i have a couple of sps growing about 10" from the top but want to expand. will the two lights I have be suffice or should I purchase a 3rd one? Thanks in advance
