No schemo needed actually.
It's just LEDs, glued to a heatsink, wired in series, and attached to a commercial led driver for each color.
Keep track of the anodes n' cathodes n' add up the forward voltage drops to size the drivers.
If you can string beads, (and speak solder), you can build a LED array in half a day.

hmm, i may have missed something in the thread, but, i don't recall alohamahalo posting what he actually ended up using, just what he thought about using. ?? unless the below was what was used in the final design and just wasn't mentioned?

4 x deep red:660nm,5w, 2.8v, 1a
2 x far red:740nm, 5w, 2.6v, 1a
1 x blue:440nm, 5w, 3.6v, 1a
2 x power supply:24v, 6.5a
3 x 3023-D-E-1000PmA Wired BuckPuck (one for each color)
weezard, what up man, thanks for the reply. (gonna go all creeper for a minute) but i feels like i've known you for the longest time, because i've lurked around this place since "the perfect LED grow thread" but i've finally built up something like the courage(more like heat is killing me, and i have to do something about it), so after years of on and off research i'm going to build something(and post every now and then also)(hurray for run on sentences). I think if i can diagnose electrical gremlins in many a auto, as well as run new harnesses, i should be able to figure this out(been soldering for years nows).

Yeah, basically, i'm rreealll leery about ordering something from china and hoping i got what was advertised/asked for, as well as having really weird dimensional requirements(not being able to find something commercial to fit).

then not wanting to build a current regulator/diving into how i think that stuff works(because i'd rather buy a buckpuck--which also does neat things for getting rid of extra voltage, and doing so very efficiently, but still finding specifics on that). Buying a bench supply just to build a few small arrays doesn't seem logical.

wow.. went a little overboard on that there post. so, here is where i'm loosing this battle a little bit. lets say 5w LEDengin 660s min Vf=2.48 max Vf=3.44, ok, so thats 1volt ether way, which is a sizable amount with anything more than 3 emitters in a string, without testing each emitter.

Next issue is driver, i've been reading through, and yeah those meanwells, but their current output is way over 1000mA(but 12v is good for a small string). So, ultimately, there is my killer, finding a power supply with the right numbers to fit these LEDs.

Then, ok, buckpucks for current regulation and they come in 1000mA formants, and are(supposedly) good for up to 18w strings, and, in the process are good for cleaving off extra voltage and do so very efficiently(forget the science/electrical theory behind why). right.. so, why haven't i just bought the stuff and built it with that "knowledge" in hand... because. wwayyy to much theory for me to be blowing up $10 emitters.... xD lol

Honestly, bluntly even, i'm just looking for a A goes into B. Unfortunately, i ether have huge wholes in my understanding(aside from smaller but, still very noticeable wholes), and i am unable to find a driver that meets my needs, or i missed something that says they are "smart" and adjust for you(which i'm nearly positive they don't)

yeah..
Wav3F0rm Reviewed by Wav3F0rm on . help with home made led lights aloha, sorry if this has been asked in a different thread but iam a newbee here. im trying to make a small led grow light with 5w ledengin emitters and was curious if anyone knew of any led drivers w/ dimmers(so i could control the spectrum) that would work well with these. iam using 2 deep reds(660nm), 2 reds(630nm), 2 far reds(740nm), and 1 blue(450nm). i was planning on running each band on its own driver and i wanted the far reds to be on its own power source so i can use it on a Rating: 5
