Looking for diy led ideas for adding more sprectrum

[dazoc]

Been running a rapid led diy kit for my tank for the last 3-4 years. Right now I have a 6’ wide, 30” wide with 7 rails. I have 2:1 ratio of royal blues to neutral white 110 to 55 chips. The fixture is 16” off of the water. They are ran with a storm controller. Channel one white 52 power of 255, channel 2 168 of 255.
I have a par meter that I am going to do some par reading this weekend. But I still want to try to add some more spectrum. Rapid has suggested the following.
24 violet 410-420 nm
24 hyper violet 420-430
4 720-740 red
4 620-630 red
8 green 520-53
Are they off base? I would like to put together an order this month.
Is this way off base? Is there a better way to do this, are my number of leds off? Better way to switch this up? All insight, and suggestions appreciated.

Thanks,
Eli

Never seen these lights, interesting. Sorry I can not provide any help!

What are your goals?
More "PAR"?
Different overall tone?
Favoring a "color"?
Are you going to replace some bars or just add?

In a general sense their suggestion is just fine to add to what you have missing or have lower amounts, though depends on the neutral whites spectrum.


Violets/IR fine additions.

In a very GENERAL sense your orig config after adding the above lacks reg. blue and cyan component.
Note I'm ignoring the green or reg. red, both of which you have plenty w/ the neutral whites.

Considering your are already dimming both of your current channels, you already feel you are sort of "par-ed" out?
Effectively running 11 Whites and 72.5 RB's..

"IF" you added 24 each of violet, h-violet, reg blue,cyan and run those at "full" (orig array run dimmed as you stated) , you broaden your blue "patch"..

Consider this a GENERAL improvement in spectrum and a rough estimate...

Orig "look" w/ dimming factor applied.

First, thank you for the reply,

I guess my overall goal would be to provide a more useful light for coral, with adding some more pop. Bring it closer to the rapid aurora 2 puck kit I have over my sump. To me that look is more visually appealing.
I would honestly just add to my existing rails and separate lights and run them with new drivers and add them to new channels.
I am open to your suggestion for what to add to achieve my loose set of goals?

What the rapid puck rough est look is.. White dimmed 50%, all others 100%

cyan/green are interchangeable for the most part

The best color you can add for pop in softies and lps is 460-470nm blue, which unfortunately doesnt exist in American LEDs unless you buy a full reel from the factory.

Violets also make your tank look darker because your eyes arent sensitive to these wavelengths but they deliver as much PAR as regular blue LEDs. Theres no evidence that wavelengths between 400-450 are better/worse for growing coral. I have stacks of 50watt 395nm LEDs and they arent over my reef tank. I save them for glo bowl at bowling alleys.

I was the one who started the whole neutral white vs cool white LED thing. The problem with neutrals is the already have significant amounts of green and orange/red, but you cant control it. Cool white plus warm whites or reds on discrete channels gives you a lot more flexibility.

Actually you could combine w/ proper selection..
"Shopping" CREE bins on stars may be a bit more difficult.
The trend is lower nm blues is better.. right or wrong.
