I'm going through a similar debate, trying to get it right between my LEDs before and my ATI T5s intensity now. I killed a bunch of nice corals after being away from LEDs and cranking them up. Now I'm very paranoid
But since switching to T5s a couple months ago corals are settling down and getting colors back
Not saying I won't ever do LEDs again, very tempting... [emoji57]
But I've been through most of them except Radion. I've done LED hybrids and just LEDs and I keep coming back to T5s.
I have a couple of 48" Reef Breeders LED Royal Blue strips to compliment a 48" ATI sunpower fixture and it seems night and day to the corals as my last LED fixture.
