The Black Light Blue is a Black Light rendering at 400nm, just under the actinics true coloration range of 420-460nm. And yes they are ok to use in a FOWLR, fish only with live rock tank. But not enough light for corals. Not by a long shot. You want to think about at least the 260-300watt range for corals.
