Well, even most halides make a good deal of UV-A (DE and SE).... if you stare at them long enough they can cause eye problems. Im just saying, I dont think we have to get too worries about providing enough of certain spectrums to corals with skylights... theres plenty enough to go around of just about every spectrum so who cares if the glass blocks 10% or something...
