Lets argue !!!! Metal halides Vs T5s Vs Leds
I've been super happy with my radions. I was also thinking about the whole t5 retro but in the end I didn't need it as you can control the spectrum from your computer and it would be another yearly bulb replacement. I'm going to have to research this 52 fixture though as I need spread in my tank more than anything. The radion 2 is doing good but they are just lacking slightly(maybe four") in between each of the three fixtures I have noticed over time.
