Well I am new to the LED's so all incite is welcome. They are about a foot above water level and I get good spread at that height. I took well over a month to bring the lighting up that high, and house sps only under that lighting right now. Most of them are shallow water specimens, and so far seem to do well under the high lights. But yeah I have heard that they can be incredibly strong even if they don't seem to be as bright as halides.
