LED grow lights... input please.

[PearlJamFan]

Ok what I have now is 80 Red in series of 5 with 3 660nm and 2 630nm per series, I also have 3 blue per series, then alternate them 400, 432, 400,432. So for each breadbord I have 80 Red with 68ohm resistor per series and 15 blue w/ 68ohm resistor per series . Each breadboard put's out 7.7w of red, and 1.2w of blue.

Here is the power breakdown.

Red per breadboard:
* each 68 ohm resistor dissipates 27.2 mW
* the wizard thinks 1/4W resistors are fine for your application Help
* together, all resistors dissipate 870.4 mW
* together, the diodes dissipate 6880 mW
* total power dissipated by the array is 7750.4 mW
* the array draws current of 640 mA from the source.

Blue per breadboard:
* each 68 ohm resistor dissipates 27.2 mW
* the wizard thinks 1/4W resistors are fine for your application Help
* together, all resistors dissipate 136 mW
* together, the diodes dissipate 1080 mW
* total power dissipated by the array is 1216 mW
* the array draws current of 100 mA from the source.

Total for project:

Red total: 480 red, 288 @ 660nm, 192 @ 632nm
* each 68 ohm resistor dissipates 27.2 mW
* the wizard thinks 1/4W resistors are fine for your application Help
* together, all resistors dissipate 2611.2 mW
* together, the diodes dissipate 20640 mW
* total power dissipated by the array is 23251.2 mW
* the array draws current of 1920 mA from the source.

Blue total: 90 blue, 45 @ 470nm, 45 @ 400nm
* each 68 ohm resistor dissipates 27.2 mW
* the wizard thinks 1/4W resistors are fine for your application Help
* together, all resistors dissipate 816 mW
* together, the diodes dissipate 6480 mW
* total power dissipated by the array is 7296 mW
* the array draws current of 600 mA from the source.

23251.2 mw x 7296mw = 30w of LED power, should be equal to a 250-350w HPS?

PearlJamFan Reviewed by PearlJamFan on 07-06-2006. LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.

take a look

[sheist]

shit looks damn impressive..

here's my input, in after lyk 5 months of silence lol

www.spectrumled.com.. ..flood lights.. 60LED bulbs, screw into a standard light socket..

jus orderd a few reds... 800w CFL, 2kW mh (nOt set up yet) for veg.. the red LEDs for flower...

[sheist]

any updates anybody?? who's doin it?

[Aaron385]

yea LED'ers.. I want to know how its been growin with you pimps that put your fundage on the line for this experiment. I respect you guys for this and I have been doing my part to try new things as well.

oh thank god i found this fourm, ive been studing these lights for some time and they are a very very good investment (also very very expensive) these lights use a avg. of 2watt and are a perfect spectrum of light....

instead if typing all this again, check out the link to my group @ myspace

here is the thread (if youre not logged in this may not work)

if not... then click below and look at the forum post called : L.E.D. lights against HPS and MH (you'd be surprised)

my question is will they get plants to go into fruit (or bud) production and sustain the levels of energy supply required to produce fruit (or buds) to their potential.. Nasa grew lettuce which can be done with the weakest of floros so Im not convinced.. I have found floros just dont even come close to delevering photons at the energy level or intensity (not nm.. we all know they can beat in nm) required to force flower or bud out plants. I may however concider using them for VEG since they definatly seem to have potential there.

So one, to lets say 6 leds
red, orange, blue, green, ir. uv. or any combination there of, will provide enough light for each plant, or is it a whole room.
I have a fert thats in pill form, it weighs 5 pounds each. Its simple to use, just pill in 100 gallons.
If joke goes over you head ,,,stand up.
After 5 months no one has data on what the Grams/watts/month data.

I'm betting the LED's wont produce enough lumens or a varied enough spectrum for the plants to grow. Remember the sun is the best source of light, and going into LED technology is moving very far from the perfect light source.

Noble Idea, but in everything I've learned about growing plants is the light intensity is very important as well as a nicely spread spectrum. It is known the Low Pressure Sodium is a very efficient intense light, but its narrow yellow spectrum makes it as efficient as growing with an incandescent.

I still hope it works, but I have my doubts.

Welp this thread is 10 months old. Lots of input and salestalk being echoed, several people and projects are going - but does anyone have any decent output worth mentioning from these LED experiments?
