LED options for 180

[lngrhaul]

So I've been reading here and elsewhere about the options for good LED lighting for my standard 180 gallon (6'x2'x2') and would like your opinions on what I think are my top 3 choices.

My budget is low so can't do the Mitra or Vertex options.

Considering the AI, the Radion or the new Kessil a350w.

I am also looking for guidance on how many of each I would need. I think 3 Radions would do it but would 3 of the AI be enough? And with the Kessil's - the specs say 3 would be enough but can we really trust that?

Thanks in advance for any words of wisdom
