Decided on building LED Fixture

So I've decided to go the DIY route for an LED fixture.



Im pretty much going to follow Jerad's DIY with a few small changes and thought I'd ask opinions, mainly on LED placement.



This is for a 48 x 12.75 x 20 tank



I haven't decided on a heatsink yet except there will be 2, each about 19" long.



Option 1 (Jerad's build with no changes)



Most likely going to use a 36 Ultra Premium LED Kit from rapid LED if I can't source the parts from my shop



Mean Well ELN 60-48P drivers



LED positioning

|B-W-B-W-B-W| |W-B-W-B-W-B|

Driver positioning

|1-1-1-1-1-1|D1-D2-D3|1-1-1-1-1-1|

|2-3-2-3-2-3|D1-D2-D3|3-2-3-2-3-2|

|3-2-3-2-3-2|D1-D2-D3|2-3-2-3-2-3|







Option 2

Pretty much the same only adding in 2 red, 2 green, and 4UV into the mix along with the original 36 from the rapid LED kit.



And this is where I need the advice.....where would I put the extra LEDs and on what drivers would you run them on for best results? I have an Idea but would like to see what the experts think. (mixed reef tank)



I'll also be building an Arduino based controller with LCD Screen...I like it because I can expand it to control other things as well.



Let me know what you think.



I'll also be updating and adding pics to this thread as I progress with the build.
