OMFG It's for sale and it's cheap!!! I think I'm gonna shit MYSELF!
So, whats shakin' bakin'? :dance: I'm new here. Actually this is my first p:thumbsup:st. I'm thrilled with the prospect of using LED growlights. However none of the ones for sale are quite up to PAR, haha I made a joke, yeah I'm a dork. I know this thread was started with the intent of Turtle420 getting a custom job done. I am thinking custom is the way to go. I'm going to look into getting 2' x 4' panels made with equal parts blue (400-470nm) and red (620-670nm) in 48 4' rows on each panel. I read somewhere about an experiment that was done with pusating light to increase yields... the LED's could be set for two on/off cycles each second during flowering (it would be like 12/12 (equal light/dark) but it would be a 24/7 flicker. Anyone know anything about that?
Turtle what was the cost estimate for your project?
TCreator, nice links. theres some good info in some of them.
Why did this just die?
Bump Bump Bump... what is that. It's just the monster under your bed.
Ferment... Now damnit!
u can just order the bulbs, according to the website you can screw'm into a standard socket.. so I'd suggest u get a couple of those bul bsocket plug things and make ur own fixture, save urself a bunch of money..
their fixtures are lyk 300 n wutnot.. just get the bulbs..
remember.. to start them off use more blue spectrum, thats what they need more during vegetative growth.. put in a little red spectrum to keep the juices flowin..
Is anyone aware if there is any drift in an LED's wavelength (what is the actual light output of an LED rated at say 635nm?) Is it something like 625-645nm in actuality? Just thought I would bring the question up, I will email an LED company and then post the answer up here.
nothin lyk that at all.. its the spectrum of light.. plants do much better with blue spectrum of light during vegetation.. one of the most concentrated areas of wavelength is about 415nm on the spectrum scale.. the 635 is in the red area, that wavelength is strong but it promotes flowering, so its for the flowering stage mostly.. u can use a little of it to promote ur vegetative growth.. when u have the red spectrum on for flowering, use a little blue spectrum, tthis will help the plant continue to grow and mature.. its the wavelength, you're thinking lumens...
lumens are measure of light seen by the human eye... we can't judge a plants growth by a human measuremant.. when plants use the light for photosynthessis, they're absorbing the blue and red wavelengths.. you should be in just a good shape as u'd be if u tried growing with cfls.. cus ur still providing the energy source..
No. I am thinking of the wavelength measurement of nanometers. I will take your example of a 635nm LED. Now this LED is sold as 635nm. Is 635nm it's median wavelegth? Does it for instance product light in the 630nm and 640nm range? I am not in any way refering to the lumen output which is a useless measurement as far as plants are concerned.
oooooh... then yea, it produces light in the 630-640nm range... out of the other parts of the spectrum, the 600s

But yeah, when I contacted the company, the guy gave me the specs for their LEDs... and there's the central nm, and a "range" of wavelengths that the LED also produced... so you're right.
I'll write what happened with the custom setup later...
BTW: LOL!!!!
"Ferment... Now damnit!"
lol lol
This site doesn't list prices for their products and they wont answer price questions by phone on the weekend and no email contact :cursing:

They still seem to have awesome products though. The rigid LED edgelights in 1/2" width with 48 LED per foot looks nice (that one is not on the site but in their brochure.) They have 12/24 LED's per foot on the site still nice.
So far I haven't been able to put together a 2' x 4' panel (on paper) for less than $900. ($1300. without weeks of tedious soldering.) Let's see if these guys can do it for less.
I love this little guy :dance:
oooooh... then yea, it produces light in the 630-640nm range... out of the other parts of the spectrum, the 600s indicate the highest photosynthetic response.. the 635nm LED is RIGHT ON IT!!! so if u throw those bulbs on, u're doin a real good thing..
