Kessil a360x has been proven by BRS to have the best spectrum for coral growth. Its also the closest spectrum to T5s. I have 4 over my 48 inch tank and get plenty of PAR aswell. Also the shimmer is unmatched by any other light. But tbh almost any LED nowadays will grow corals fine. The new G5s have good spread too. Will take pictures once i get home since my sister is taking care of the tank for me today lol
