Their 32 watt light that stretches across the top of the rim.
OK yea, I see that one. Ok here is the thing.
From a geometry and marketing point of view your 30" is err "not standard" for most brands.
AI blades come in 30", your Nicrew, and a few other that you would consider cheap.
Second issue is the narrow tank. So "pucks" have an issue being squarish. If you cover the 30 you spill on the 12" side.
Like a 15x15 footprint of light.
Next is what do you really want to grow? High light corals will need high light well obviously.
Now keep in mind that the Nicrew you have if run at 100% can probably hit 70-100 par at your substrate level.
Next what "color" do you like?
Then what control do you want?
How will you mount it?
There is anything from these cheap lights that fit on a rimless tank (x2) or rimmed under 3/4" (check specs)

$739 plus ...
or 2 Radion gen 6's are also in this league.
40-80w if well placed is really all you need to get adequate par for most stuff.
Want the best spectrum.. Pretty open question and I'll let others debate that.
Typical "cheap" led par ..Will help in judging what you need for what you want..
typical recommendations
Higher light corals such as SPS do well in 200-400 PAR, while many LPS corals prefer less light (50-200 PAR). Soft corals usually prefer lower amounts of par (25-125).
