On my biocube is use 22 LEDs (granted many of them are 3-up stars) packed into a tight rectangular array similar in shape to a metal halide reflector. Works well.

I would also recommend adding some ocean coral white and true violet LEDs to that mix there. For me they took me LEDs from meh to awesome.

Thanks for the input, so are "ocean coral white" the 3-up kind? My "UV" are Violet UV 3W, I guess that varies from True Violet?

Thanks again
