I've heard that about them. So far, it's doing well, but I think I may just order new lights today. I was looking at a dual T5 HO which would be 2x54w, but I think I may just cough up the dough and go for the quad T5 HO 4x54w to be safe. Would the 4x54w be enough? It would be 2x 10k and 2x actinic.
