I have 2 Orbit marine pro and 4 T5 bulbs. I can grow/keep alive most SPS but the growth is painfully slow. In a year have gotten good encrusting, but very little vertical growth even with the light 10 inches away. My parameters are constant with dosing pumps and routine testing.
I have lost one LED row on he newest orbit but didn't bother getting it replaced as I'm lazy and want something different in the near future. The light has very narrow coverage as said above. I would not get these if you are looking to grow higher light corals.
