I agree my coral vendor runs T5’s his colour is amazing. I ran a 8 bulb ATI I got for a steal on my 120 lived it but it was non dimmable and I missed the Radion glow. I should have just sold my Radions and bought a reef bright. I may try that new hybrid fixture BRS was showing however, at this point I’m almost scared to change anything. This tank has been a challenge.
