I had Marineland totally replace my 72" Pro Series light after a ton of issues like their tech dropping my first replacement in the tank and a large blue flame shoot out after he left.
He came back with a brand new box that said new or updated system on it and replcae my light with a total new light.
Well Marineland also agreed to send my 4 Units of the 24"-36" Reef Ready LEDs.
I just added them to my tank along with the Pro Lights that are already on it. They are on a time that goes on and off with my MH. Well the MH is on the Pro Series built in timer but I just set them for the same time.
As long as any corals you have that need strong lighting are within 12" of the LEDs they are just fine. Once you get beyond that down to 24" any Low Light corals will be ok still but after that it is just visual to our eyes.
I am very happy with the extra light I am getting and if you turn them off, what I used to think was a lot now looks far less bright. I basically supplement with them and they do a fine job. I mean who has all their corals at the bottom anyway and anything I do the MH get.
That is another thing. I have the cheap Marineland Bulbs and they are 150x3 MH and I have corals at 27" that are growing very well. EVEN AT 150watts corals that are sitting within 18" are getting plenty of light. I can put any coral in there. I would rather have 250Watts each but they work great.
Ok about the LED's I have this pic here and you can see them on top. FREE LED's for me. $1000 at the store.
