Led layout

[Balz3352]

Got the full spectrum rapid led kit for my biocube. Any suggestions on the layout of the leds? Heatsink is predrilled. I'm attaching a picture of the predrilled spots and leds and amount.

1 red
1 green
4 uv
8 cool white
10 royal blue

Thanks ahead of time!

I'm also putting 2 moonlights (royal blue) in between row 2 and three in between columns 2-3 and 4-5

Ive never built an led, so not sure on the layout, but this article might be of some use to you in figuring out the config you want

I've read that and was looking for it again.. Thanks. Guess no one has input on layout... How about which strand to run the red, green, and uv... Should these be on whites or blues... I've heard red and green should be on the blue and the uvs on the white? What do you guys think?

 

[sethsolomon]

I personally would suggest ditch the red and 1 cool white and put 2 warm white LED's

Red LED's add too much red spectrum for the tank. And a note on rapid LED's UV led's, they are not true uv they are a violet 400 nm spectrum. UV is 399nm and lower. I do recommend putting 2 true UV led's in the fixture but you will have to order them separately. I would also swap 2-4 of the royal blues for regular blues.

 

[Balz3352]

Alright I just ordered 2 regular blue and 2 warm white leds from them... I'll ditch the red... Do you have a place that sells true uv leds you suggest?

Which strand would you run the now green and uvs on

Here are some links to true UV LED's.

Do you suggest a certain spectrum or just sub 400
one of those links is 380-385...another 365-370..the last 390-405 does it matter?

 

[sethsolomon]

I personally would just pick 2. and replace 2 of the violets with 2 of your choice. I am not sure of of the different spectrums of UV.

 

[Balz3352]

Any suggestion on running the uvs on blue or white... Same question with the green

 

[sethsolomon]

what current are you running on each driver?

 

[Balz3352]

I don't know how do I find that out. They are the eln-60-48d drivers

 

[Balz3352]

Sorry for all the questions.. I really appreciate this!

 

[sethsolomon]

you manually set them on those drivers.

 

[sethsolomon]

which ever you have the uv's and green on you will have to underdrive them.

 

[Balz3352]

Ok I have 2 drivers. One primarily for blues and one primarily for white should I put them on the primarily white strand

 

[sethsolomon]

Yah I would use them in the white strand and under drive the whites. 700mA should do the trick

 

[Balz3352]

Sweet thanks a bunch!! You have been awesome!

If you have any LED questions at all let me know. I have done a few LED builds now.

I agree. Keep in mind that you need to set your driver's to the lowest amp rated led on the string. For example, you can push royal blue's (xpe) to 1000mA, but if you put a uv on your blue string that can only handle 750mA, then 750mA is as high as you can run that string.
