I picked up 6 of the Meanwell drivers Dipan had listed so I am looking at a DYI LED for my 90g tank. I was just hoping for some input on the LED Placement and colors.

Here is what I have



Heat sink is 20x7.25 so I'll use two of them unless heat would be an issue I could just go to one 42 inch to cover the entire tank. I would just leave the middle two inches free of LEDs since there is a brace there that would cover the light.

I am using the 1 XP-G to 2 Blue mentioned from the LED Presentation.
I could up the white drivers from 12 to 14 LEDS if I need more light and just change the spacing. (Typing this I will probably do so even though it changes the 2/1 ratio)

For the blues I will use the XP-E LEDs. Should I use all RB or a mix of RB/Blue?

I won’t know about lenses until after the lights are running over the tank to see if I can focus the light better and still maintain a good blend of the colors and coverage. I am expecting that I will be able to add some tighter lenses on the ends to keep more light focused on the tank and then widen them a bit as I move into the middle areas of the tank.

Any other tips or changes you might think of?
