I’ve wanted to implement some macro algae into my sump but haven’t been able to find a light that doesn't cost an arm and a leg (I’m looking at you Kessil). I would plan on doing some more ornamental macros as well because similar to @Tidal Gardens I also think that a refugium could be a place of interest as well with a tank. A high powered sleek light that could really grow some nice macros, for free, would be awesome to have.
like the fact you dont need another outlet the gooseneck is included no need to purchase one also you can bring it down as close to the water as possible no 3d refflectors needed great
