LED Schematic

I have a 300g tank and will be putting (4) 18” LED fixtures over it with 66 LEDs.

6 –Violet
6 – Blue
30 – Royal Blue
10 – High Noon
14 Cool White

With the following layout. Comments and help is highly wanted!!

Thanks

Don't depend on the V's to help with PAR, but I do like the mix. I'm not sure if the HN will be too much white/yellow, but very cool. On my 75G, I have 48 total, and I will be adding at least 12-14 more RB's to even it out and be able to take my whites up more than 50%. What are the dims of the 300G? Also, the drivers you are going to use govern how many of each LED you do, so keep that in mind (I'm sure you are).

300g dims are 96" long x 30" tall x 30" deep x 24" wide

At moment going with 28 drivers from Reef LED Lights

Whoa...28 separate drivers?? 2-3 LEDS per driver?? Crazy control, but wow...

No, I will have (4) fixtures with a total of 264 LEDs on 28 drivers or approx 10 per driver.

Hehe...ma bad! I'm reading too fast. I know you're coming from MH's, but that's a ton of light. Dimmable will definitely help. Crazy awesome build

The 6 violet and the 6 blue, are those actually red and green? Or do they contain those spectrums? On my plates, I have (2) reds, and (2) greens, and they actually put out a red and a green color to them. If they emit the red and green color to our eyes, and have no growth value to them, I would cut those down a bit, maybe 3 each, instead of 6? (to add a few more growth output led's like HN, CW, or RB) Otherwise, make sure you can dim them to control the red and green value.

I like the lay-out. My vote is go for it!

Violet is the farthest from the red/green side of the spectrum. Cyan is quite green to the eyes, but Blue is blue. There are specifically Red and Greens, but OP hasn't hinted to using those atm.
