I like my AI gen 1 mainly because of no heat and no need to change bulbs. I dont frag to sell and am not into the latest named coral fad so what ever final color colony my frag ends up being is fine with me. Thats not to say LEDs dont grow colorful coral, Ive been giving away lots of trimmed pieces. I havent used supp T5 in years and will never go back to shimmerless, endless bulb change tank slave. My all time favorites are 400W MH 20k but even changing out 3 bulbs per year was a pain. I have a set of Radion G2s but am too lazy to install /acclimate to them too.
