More blues only please

I’m looking for a 400-500nm, 20KK LED lamp. I only want my blues baby, no whites “full spectrum” baggage, just the blues.

My setup will use minimal white light. White & shimmer will come via controlled 160we (blue tuna). Lamps will be sitting over a sps only nano/nano. In this tank I heavily favor coloration over growth. If I want more growth, I’ll add more white light.

I’d be happy with a fixed color lamp but bonus points would certainly be given if there was an option for scheduling changes to; 1) nm within this blue only spectrum, 2) PAR.

Did I just describe a version of the 160we blue tuna on “blue only steroids”?

I do understand ~33% of this lamp already covers the 400-500 nm spectrum. In my mind this leaves 66% of spectrum I don’t want. I wonder what 100% focus within this spectrum might look like. If nothing else i would think it should cost less to produce and simplify design. Does something like this already exist? Have these lessons already been learned?

If it sounds as though the cheese has slid off my cracker or this has already been discussed ad nauseum, I plead that I’m just now back to this obsession after a 20 year hiatus, or maybe it was a respite ? who knows, could have been both . Needless to say, I have some catching up to do.

BTW - what’s the difference between the 3 flavors of reef roids; Regular?, Nano? and Pro?

Geisemen makes a super blue I think that's what it's called. It's practically UV bulbs. You can't even tell that they are on until the corals fluoresce.
