I have many friends that only run radions so that bad stuff you are hearing makes no sense to me.
I have 2 xr 30 gen 4's that I bought for a song for my upgrade. They work very well .
T5 they are set and forget. Ran them for 14 months on my 120
They grow all corals well.
Just changed them out for MH, metal halides,
as they are my prefered light of choice.
Upgrade will be MH and radions.
You could get a black box led. They worked very well on my nano for a year and are pretty inexspensive too.
It can be confusing as their are so many types out their.
2 orphek light bars would be another awesome choice.
