LED panel help please

NinjaCorey here, stopping by to get some help. So if you’re good with electronics (wiring and configuration). I have a small stealth grow and had a small HPS light in it. I had to take it out due to heating problems. So I decided to make me a custom LED light panel. I was wondering if my list sounds right and if my panel will work. So just let me know.

I am planning on using LEDENGIN LZ1 5w series. The colors I will be using is Warm White (3100k), Blue (465nm), Red (625nm), Deep Red (660nm), Far Red (725nm – 745nm).


LEDs:
Red: 2.5v, 625nm, 1A, 5w

Deep Red: 2.9v, 660nm, 1A, 5w

Far Red: 2.6v, 725-745nm, 1A, 5w

Blue: 3.6v, 465nm, 1A, 5w

Warm White: 3.6v, 3100k, 1A, 5w

Resistors:
Red: 2.2 ohms 5w

Deep Red: 1 ohm 3w

Far Red: 1.8 ohms 3w

Blue/White: 1.2 ohms 3w

Power Supply: 12v 90w 7.5A

Does this sound right? Did I miss anything? Should I change anything?
I plan on making the panel, find something to encase it in and add 2 intake and 1 exhaust fan.

I plan on using 8 x Red, 4 x Far Red, 4 x Deep Red, 4 x White, 5 x Blue
So I have a 3.2:1 Red to Blue ratio. Good enough?

The panel design is as follow.

R = Red
D = Deep Red
F = Far Red
W = Warm White
B = Blue


RFWFR
RBDBR
WDBDW
RBDBR
RFWFR


Any other designs are welcome. I don’t know if this design will work. And I don’t know where to place resistors. So help on a design that will work with resistors would help.
Need more info just let me know.

Thank you – Ninja Corey

Sounds like your on the right path. I believe the leds can be daisy chained together, but I'm not sure how many max per strip with one resistor per strip. It gets technical, and i have never studied electricity beyond basic automotive applications and rudimentary home wiring.

Click to expand...

yes it is. also the resistors i have listed are for the same LED like the red resistor is for all red and blue for all blue..etc

my series are going down. so 1st serie is RRWRR and 2nd is FBDBF.. etc
i get a total of 13.6v drop and each diode has 1A forward current for the 1st. 1A = 1000mA. safe to run at 900mA. with 13.6v drop divide by 5 for 2.72v.

so... 20v line with 2.72v per diode at 900mA i get a resistor of 7.2ohm 5.8w ? sound about right? did i go about it the right way?

bump???????????

going to need a big heat-sink

I wouldn't bother with the far red. I'm not familiar with those diodes, do they come with optics?

I don't know anything about electricity so I can't help with that.

But as far as the far red spectrum, it is in fact a good thing. It's called the Emerson Enhancement Effect. The far red spectrum by itself is useless, however, when infrared light above 700nm is combined with red light below 700nm, the combination actually increases photosynthesis. Just be aware that light above a certain nm is not visible to the human eye so if you use them they may appear to be off or not working, when in fact they are.

I can't remember the exact specs but you can search on Emerson Effect and find out.

If your thinkin about only using leds for the entire grow your gonna get crap flowers, using a low watt high intensity light is a must!!! combine the two and you should get get results...

LED's grow better plants. Check my journal in my sig. Anyone who talks trash should try growing a plant first.



Far Red and White are a waste IMO. I have had great success with dual-spectrums. Just switched to a 660nm all red ufo.

looks quality but wheres the bulk??

looks like most of yoiur room is stems stretching to the light!!

characteristic of a pure Sativa. Tons of colas. Branches can't support the weight.

taken a week ago:

"for clorophile A you need 400-430nm of blue and 650-670 nm of red. for clorophile B you need 420-470 nm of blue and 620-650 nm of red.
peak absorbtions are at A: 425 and 660 nm, and at B: 450 and 630."

this is the led unit i will be using 1 Custom 120W LED Light with R,B,W,UV 6/1/1/1 ratio(1:1 ratio of the 660s and 630s)

good luck also some units have ir inthem im not sure what this does you may want to check it out tho

i like seeing people having success with leds the technology is coming along way, good on ya mate. saving the enviroment one step at a time..
