I prefer fluorescent myself. I am using T-8 N.O. fixtures on my plant propagation/ grow out tanks and have excellent plant growth, and color. I use 2 triple tube lights 150 watts over 40 breeder tanks. It throws a ton of light into the tanks. The PAR is well over 100. I have Alt. Reinekii that is completely red. Even the tops of the leaves are red. I also use T-5 HO
lights on my display tanks with excellent results.
I understand that LED
are becoming the rage for tank lighting now. I have never used them, so can't comment on them.
