diy LED Lumina 5.2 Purchase help.

Barely crawling and trying to run.. Just a joke.
Just get a Storm or storm X Later you can reprogram them to your hearts desire..

Thia will come easier to me than you might think. Ive been in car audio 15 years. wiring will be a breeze for me. im already half 1 through the first arduino project. would be done if I had 5 more 220ohm resistors for all seeing eye.

its just in mobile electronics never really needed to know any other voltage other than 12. no reading amerage other than of relays. really no need to even read ohms law. so yes it might take a second to understand the jargon

how fitting it was that I was the one hundred and first reply

It is not the hardware but the software part that is.. err.. taxing..

Hate to bump an older thread but it's relevant to a question I have. What power supply specs would I need for running two lumia 5.2s in series and one more on its own to just use two sets of 5 ldd drivers?

Layout:
Channel 1 - 3 Hyper Violet and 2 CREE XT-E Royal Blue (Actinic channel) (18v @ 700mA)
Channel 2 - Royal Blue (base blue spectrum) (16.5V @ 1500mA)
Channel 3 - 3 XT-E Netural White and 2 XT-E Warm White (base white color) (16.5V @ 1500mA)
Channel 4 - Turquoise / CREE XPE2 Blue (enhanced color spectrum) (17.2V @ 700mA)
Channel 5 - 3 Hyper Violet (430nm) and 2 True Violet (410nm) (Violet channel) (18v @ 700mA) *as of June 1st 2014

Assuming you are going to use LDD-h's so max current/driver is 1000mA,

4100mA per set of 5..
8200mA for 2 sets.
Figure 9-10A

Then add the voltages in the series 2 to get max V needed..
18x 2 = 36V.. Add Driver differential of 3V and round up.. 39V = 48V

48V 10 A

You're recommending a 480w power supply? Uh, what? Each Lumia 5.2 is about 70w maximum, times three is 210w. Give 20% extra wattage, and you get 252w, so a 250w supply is fine.

Yea, doing the real calculations is much better. I just added the Ldd output
though each will have a much lower real wattage..Like you stated:

135W for the 2 in series
68W for the one

I'd give 25% headroom so 300W (getting closer to 450.. )

6A works fine...
Or this:

10a Gives lots of room for expansion..

i JUST finisehed my lumia 5.2 build.....

here is my build on our local club forums --- http://atlantareefclub.org/forums/showthread.php?t=105242

I went with 180w for each pair of Lumias... that should be more than sufficent. If I want to add more lumias, I will just buy more...not a big deal

for the $100 for the 10A ps you could go from 3 to 1 power supply...

I've got 6 Lumia so I didn't have much choice. 180w was better

Awesome thanks for all the quick replies. I was already planning on the meanwell nes-350-48 so I'm probably going this route just glad to be reaffirmed in my choices.

 

[Tacostrk]

Also I'm planning on supplementing with two 36 in t5s on my 40g breeder. Should I bother going with the let micro dimmable fixtures or just standard ballasts? I will be using the o2 surplus boards with bluefish mini.

I have same boards...they are freggin sweet. That board alone makes the build easy and super clean. I don't know why he doesn't distribute them through the led dealers
