LED advice for 20" cube, currently 250w MH

[nerdz]

Hi

Need advice, would this be okay:

3 channels

Driver 1: 12 x XT-E royal blue + 2 XP-E blue
Driver 2: 8 x XM-L Neutral White
Driver 3: 6 x UV + 2 deep red

80 degree optics?

My head is spinning! I saw some combos and layouts on a nano-reef thread, but nothing for a 20" cube...

Whole build should be ~$300. I'm not against manufactured fixture, but not sure. Kessil 350 is nice, but no sunrise/controlling options. AI SOL is nice but not much colour option. bah!??!

Thanks for any advice!

I am not sure that would match the brightness of 250W MH. If you are that kind of person that need to have your LED as bright as MH, it won't be enough, but if you just like the tank to be like 20000K then should be perfect. PAR wise I think it should be fine for any corals
