I believe these are the ones I used, but you may want to double check the pin spacing:

Thanks for looking,
I got a Jebo375R(47gal), an older generation of curved aquarium.
It's much taller than the regular 40b( 6" more?)counter-front.
And the reason i put the Red, Turquoise and blue into one is LEDGP recommended a 1:1:1 ratio, i feel that in the beginning i can just wire in bundles, and as time goes on, i can add more if needed.
It would be easy to add extra 700H with the IC sockets, so if in the future i want to separate the channel.
All this planning is from speculation on the color temp, and the amount of re-florescence that rebounds. I saw a build with similar ratios, and uses all the led I've planned.
Here is his build over a FW for the time being until he set up the salt pumps.

6 LDD Board
6 LDD Board
Hi guys,
Finally have managed to read this entire thread!
I was wondering if it's possible for someone to design a 6 LDD version of the boards? This is because I have 6 channels worth of LDDS for a Makersled nano fixture (163mm wide) and would like to hide the LDD's in the fixture. So that I only need to run a power cable into it.
Is this possible?
Cheers!

I've already posted a 3 channel version on page #23 of this thread http://reefcentral.com/forums/showpost.php?p=21090882&postcount=555. You'd only need two of them for your application. I've got extras, as I'm sure that a few others on this Forum do too, so just ask- if you want some.
please see pictures from this post

Please PM if interested, I have extra unsoldered board.

Do those require an external PS like LDD? Awesome PCB bw.
P.S the main thing im concerned about my build above is the Power supply good for my build? What kinda of ratios are we looking for in the PS?
I read that as long as the V is more, than it'll work, heard the same for Amps too.... but ive found PS with the same Volt and more than enough Amp but the power rating is only 100 watts.... now that might be just me, seems to i dont have any EE knowledge, but why use a 300+watts PS when a 100watts one work??

this is awesome!
looks like 8 channels of dimming, can we have more info on this?
cost of full assembly?
parts list?
are you offering it open source?
are you willing to build any for people?
possible to design an ldd version as this one looks to cost about $200 for the controller and drivers.
this thread rocks!
cost of full assembly? $200-250
parts list? SMD0605 resistors 10K, Recom LED drivers, Mega+TFT screen
are you willing to build any for people? no, if you know how to use soldering iron - everything else is very simple. I have extra PCB just because it is chipper to order a few then only one.
Any software can be used to run it, I saw several open source arduino controllers.
It is dimmable
All connectors from Mega are duplicated on the board so any other extension slot can be connected if needed.
For my project was needed only LED drivers, so far do not want anything else from the LED fixture.
Cheers for the 3x link. I have my ldds on order so these boards will be great. Luckily as I work at a University I have a place where I can get boards fabbed at cost.
I also received this from Meanwell to a question I had about the supplies:
In the case of the ldd-1000h for a 48V supply, where 3.5 is the forward voltage, the approximate current consumption will be calculated as such:
48V * I * 97% = 3.5V * number of LEDS * 1000mA
So in the case of two leds (efficiency will be a little lower), current draw is 150mA

OSAMA-
Here's the single sided version of my 4up LDD PcB. You should be able to open it with the EAGLE program, print it to scale, and etch it by hand.
Good luck
Thank you very, very much
