An Vertex Illumina 200 or 260 (LED) will provide enough light to grow whatever species of coral you like, and you should never need to upgrade it unless you change lengths of tanks. You can control it in essentially any manner you like. Be mindful water quality is also important for coral growth, but you gotta have adequate lighting at the same time. cheers.
