my tank is almost 4 years old at this point. It is a 30" tall 220 gallon SPS System. They are great lights impressed with the quality as all mine are still working just fine.
They are pretty strong lights. I had acros growng on the bare bottom of my system. Would advise starting low and slow increasing intensity over many weeks till you have them where you want them.
