I have two 360we's over my 65 gallon. I have had them since August and I am getting mixed results. i wanted to go from a softie tank to an sps dominet tank. Only a handful of sps have grown like weeds while the other ones bleached out or got stn. The stn has stopped ever since I eliminated rowa from my system and started to feed the tank more. i will give mine a couple more months before looking to invest in mh or another led fixtures.
