I agree. But keep in mind that, compared to a RB/CW fixture, blue and cyan ARE color LEDs. One thing that I've found helpful is to count all emitters under 500nm as blue and all color LEDs above 500nm as whites when working out a ratio of royal blue to white. I think a common mistake is to start with a set RB:W ratio, add x violets and y blues and then wonder why the final result is a fixture that is bluer than expected. Orange and red LEDs will indeed add warmth and balance the cool colors, that's why I add them to the white side of the ratio.
Holy Sunburn Batman....
Toss us a Pic of your tank using only LEDs that you recommend....
Orange and Red LEDs are suspects in Nuisance Algae...
Orange and Red are rendered to a low state of usefulness below 10 meters...
450-460nm has been proven to to grow coral...
Yes 420-430 is better but look at it this way...Just thinking out of the box....
Coral Photosynthesis is 100% efficiency at 420-430nm.... Available LEDs in this range are about 25% Efficient at given current compared to the latest generation of Cree and Luxion Royal Blue.
Coral Photosynthesis is about 70% Efficiency at 450nm...Which is better??? Provides more bang for the buck???
The final question is what grows best, looks best and is more efficient than current MH T5 Combinations...
Please toss us a pic of your tank...I'm a big tank guy and here is my pic of one of my tanks under LEDs w Cloud Movement 570 Cloud Movement.mpg - YouTube
And yes I was able to score a Red Carpet!!!
Months later and after a very bad encounter with with a MP-60 She is now much larger under our RB/W Mix of LEDs and is now hosting a bunch of Juvenal Black and White Clowns....Thank God my wife is not like that
