DIY LED build

[Tom@HaslettMI]

Here is a pic of my LED set up that I was finally able to complete.

The specs are below:

1. 54 LED total 36RB / 18NW Cree, drilled Al heat sink to run wires to connector for easy take down maintenance.
2. Using two 350W computer power supply as constant current power source (verifed no fluctuation in current with meter), each power source is running white and blue seperately.
3. An array of resistors to limit the current to 750mA for each of the white and blue power strips. I increased to even 1000mA but I saw diminishing return on noticable lumen increase. This I hope will balance max viewable lumen output versus extended life of LED. Verified LED junction temp to be 75F max.
4. Using two dimmers to adjust voltage for each of the white and blue strips.

Actually the custom cabinetry which I did myself took longer and required more tedious attention to detail then the LED setup.

I am anxious to install the 50B and see how the color combo works. So far I like the warmth of the 2RB:1NW ratio. May add the coral white that was recommended by LEDGROUPBUY.

I'll try to post more pics but so far I'm limited to only one upload and I am new to forums so don't know much how to navigate around it.

Looks great!

This is my 75 gallon with 2 overdriven T5HOs and 10 3ups (20RB and 10NW).
