Ok just so everyone knows I have built a few LED fixtures for over my display tank so I have a solid understanding of the way to build fixtures and how they work. BUT this build is for my scrubber so I am going to need some help My screen is about 10" long and about 8" tall with tons of flow. As of now it is lit with four 23 watt CFL lamps. I feed about 3 cubes a day but that can vary some due to my work schedual.
My plan was to use six 3watt CREE LED's on each side of the screen. (enough?)
I was going to use 3 red and 3 cool white on each side.
My thinking is that the cool white will have enough blue light in them while still providing other parts of the spectrum.
I have read something about blue light "overpowering" other parts of the spectrum causing people to run them at a lower power? What is this all about?
