LED grow lights... input please.

[physicsnole]

Thank you sooo much:thumbsup: that is awesome. thats just what i needed. could you take a picture of the writing on the capacitor the big round black thing on the bottom left. im just want to assure to myself that what i am doing will work and im not gonna waste alot of money. thanks you thank you thank you:thumbsup::hippy::rastasmoke:

Hey Opie;

Whites work just fine?
Wish I had talked to you a year ago. Could have saved a little money and a lot of time.

Whites have come a long way baby, a very good example is the Cree XR-c warm white.
On paper it has good specs; 2,600-3,700 degree K. In it's spectral output it has a spike at abt. 440-450nm (output of die) and second larger curve (phospher reaction) that does go up 630-640nm.

Many LED's in the warm white, spike at 375-425 and have a reaction curve that stops short of red. Makes it's white enrgy in the orange-amber-green. No usable blue very little usable red. Yet it is a "warm white". They can even have Kelvin numbers that look good.

Even with the cree's, I want to see a independent spectral graph of them before I invest in trying them. Fell in that hole once.

Hope you can understand what I was trying to say, sometimes this is all too much for an old man.

Much as I don't like those sites, here they are.... gotta like being a noob..
Pictures of Procyon 100 innards

Hope you don't mind me posting this in your thread SnS...

On one of the pics of the board (#1 I think) put a tag on the thing I broke. Pic was taken before it got broken so if anyone has ideas on what i can do to fix it that would be good. It is the thing with two wires attached to it.

Thanks a bunch for those photos. I know it takes a little time and effort to publish those. Sorry I don't know what the broken thing is. Is it the little black thing with 2 black wires? Can you get a close up or tell us what the lettering on it says? Glad the light still works though.

[Opie Yutts]

I certainly understand.

Check out this white about 1/3 down the page, CCS100A. It has a spike in blue and red, almost exactly where peak chlorophyll activity is. Looks like 465 ad 645. I'd like to see someone explain why this white is not good for growing plants. If I could only choose one LED to grow with, this might be it. http://www.bocaflasher.com/pdf/photo...2006-05-22.pdf

Great buds SnS!!! Makes my mouth water looking at it.

Please let me know if I should make a new thread.

However, info for the capacitor is as follows (my camera didn't take good closeups, not even good enough to read).
White stripe down the middle with 2 black rectangles in it
Left hand side of strip, top to bottom with light upside down
450V
220uf (funny looking u or upside down h)
722006 (M)


450V
220uf (funny looking u or upside down h)

Right hand side of strip, top to bottom with light upside down
HC
M CE (M is bolded and in a single line box with rounded corners)
+105 C

M CE (M is bolded and in a single line box with rounded corners)


Regarding the thing I broke.
Hard to say really (think need a magnifying glass which don't have) but best guess:
3 lines
F1l t1
70-0 C
D6 (not sure if 5,6, or 8. kinda looks like 6)

There was also powder in the hole when i took screw out and also looks to be some type of metal strip embedded in that plastic.

I sense I may not be around much longer to say this, so I might as well get it over with:

Why not try to find a volume discount on one type of white LED and see if you can build a stronger white light for the same price as all the fiddly 10-different-wavelength plans? So what if it's a few watts hungrier than the others for the same effect?

I wouldn't mind experimenting with all white LEDs in the future.. (like perhaps one all-white grow vs. a multi-color fixture of the same cost to build) I just won't be posting about it on this forum, most likely. Too much bitch-fighting around here. (not specifically in this thread) If you have any other good places to discuss new LED options, hopefully I'll see you there when the time comes.

Used to be on a forum for some seed bank, that got rolled over into some other larger forum eventually. I don't remember it being quite so bitchy as it is around here.. but hey, it's been years. Anyway, good luck with the LEDs. Rated a bunch of these threads up for ya while I could.

Opie,

I took one look at that ccs100a, and the (LED) light bulb went on over my head.
That is a RGB based white....it has no phosphar coating. Three dies (red,green,blue) produce the spikes w/ corresponding curve. This would be far superior to hitting 'specific' light wave length.
I see no reson why this one should not work.

When I get a chance latter I hope to look further at the rest of the specs for that ccs100a.

Thanks for engaging me in thinking about this.
Ideas are starting to flow in my mind...gotta slow it down and vape a bowl.

Yo BlueBong;

I really hope you don't leave. I'm new here too, and have been feeling my way around; been readin' more then postin' and have mixed feelings but have hope for the exchange of knowledge.

I was active on an other MJ site, in LED discussions for a few months. Problem was too much of the crap "China" panel questions and such. It seemed everyday more and more people where asking about so-called "LED grow lights" that where shit or someone was humping and spamming some crap porduct. There wound up being more mis-infomation then usable dialogue.

Funny when someone talks about the "perfect" LED light, it really should be a white light. And it should be full spectrum white light....evrything the sun has to offer. But part of the economy of use with LED is the ability to tailor WL nm. Actually the white LED Opie just referenced contains a spectral graph that really shows one LED putting out two nice red/blue spikes. Or check out LedEngin 10w LED in both RGB and RAGB.

Maybe we should start another thread?
Have you done any LED experiments so far Blue?

[BlueBong]

I haven't messed with LEDs yet, beyond trivial use. The only LEDs I have laying around pre-date the availability of 1w and above LEDs. Totally useless to the discussion, in other words.. just some random Radio Shack junk.. although I can make some nifty "eyes" with two reds and an old watch battery..

If I do a normal grow using LEDs, I'm thinking about 1 Procyon with a pair of 2-lamp 2x- or 4x-overdriven T12 P&A 4-footers in a slightly larger than 4'x4' space.

I have no money to spare right now and I'm bone dry here, (and in a lot of pain) so anything I do will be the next time I get some spare cash. I thought about making 2' and 4' fixtures (similar in dimension to the typical simple boxy T12/T8 1-light or 2-light fixtures of the same length) out of the best white LEDs I could get my hands on once I have the money.. but that may be some time off yet. Still have work to do to my car, my truck, and my house.. but in time, I'll do the white LED experiment.

I want to say the place I used to visit was Heaven's Stairway.. and I think there was an old forum there before it got folded into overgrow.. but I haven't kept up on "weed society" since those days, so I have no idea what the name of the place really was. I could be completely and embarrassingly wrong on that one. It's irrelevant, anyway. Been years now.

I came here thinking it would be nicer to deal with only people who smoke, since some of the other places I've discussed weed on were full of "DARE kiddies" and "DARE 20-somethings" who just had to tell us every day about how we're all bad people and should go to jail.. but it seems like every other day some argument is breaking out in SnStealth's thread, for example.

I think I'm annoyed because, while I admit I have some pretty toxic views on the human race, I was kinda hoping a forum full of fellow stoners would go some way towards quelling my growing rage against the species.. I didn't think coming here would help reinforce those toxic views. (there seem to be some decent people here, they're just drowned out by all the shouty angry ones)

Anyway, I'll keep an eye on what's available in white LEDs and spend some of my idle time on fleshing out the idea a bit. Not just design, but how to test different setups at the same time.

[veggii]

hey melskid-
is there anyway you can take apart your procyon and take pictures of the circuitry? ive been dying to see it. im just trying to get an idea how the procyon has its power management hooked up.:rastasmoke:

:wtf:
