Yes, I am familiar with them. Solaroasis was the company who did all the research behind those lights, and if my memory serves me correctly, they are the ones NASA tried out in space. The original design used 660nm, 612nm, and 465nm, with 15 degree and 30 degree, extremely low wattage (like 1/10th watt?) LED's, and produced some of the worst results of any LED grow light on the market, at the highest cost per watt (results at www.Greenpinelane.com). I don't know what development they've done since then, but they still use low wattage LED's, which don't have the power to grow/bloom our plants at an effective rate. The last time I spoke to LED-Grow-Master, I was told that their bars are not stand-alone lighting, that they are supplemental lighting, and you still need to use HID. Again, I don't know if this has changed since then, but I do see that you have supplemental lighting, which is probably supplying you with the majority of your growth.
If I can offer you 1 major piece of advice, since you already have the lights, use them at 3" above your plants. I know you're not going to get a ton of spread from them at that distance, but those low wattage LED's have very little light energy. Using them so high (even though the MFR tells you to do so), they're unable to penetrate your plants, which is vital for growth. Anyhow, best of luck!

Its a very confusing world out there when it comes to LED grow lights... I loved the idea so much that a friend and I built our own over 2 years ago...then another friend got themselves involved in solar oasis and I brought 3 over the last 2 years ... I know its a gamble with such a young technology but some people have to take it or nothing would be developed.... still I'm glad I own them even though they are not super effective....I guess that's why I'm using them for the mothers... they are healthy but the growth is not vigorous,, I would rather keep the growth slow on the mothers so I don't run out of space for them (so it does kind of suit me)... but I would LOVE to run them in my flower room and get great results... I will save up and get some of yours if they will perform well... running the system so cool would be heaven in the summer... :^)

2 years ago is about when I talked to LGM. I haven't seen many design changes from them since, but most companies stick with their designs. You're absolutely right though, that without companies like them, and people like you, LED's would never be where they are getting to now. Someone had to do the research and make the first products, and someone else had to buy them, which leads to furthering development. Then more companies get involved, selling their own products, and once the market is flooded, it gets confusing lol.
Anyhow, those lights would be good for mothers. A friend of mine has a similar idea with her mother, and keeps it fairly far away from her 120W. I would still move the light closer though, so that they absorb as much of that light as possible. The probably won't grow much faster, but plants really like the tailored light.

Maybe I'm too old, or too big of a square, but I'm not exactly sure what that even means.
EDIT: I looked it up (I'm such a google nerd) and apparently it is a good thing:

looking good ledgirl.
Im not a big fan of leds, cas in my opinion-they cost too much, and gives pretty much same results as using cfl-s.
Someone should do a grow using leds, and clfs, and then share the data what came out of that experiment.
Anyway, good luck and keep up the splendid work....

nice job on the grow. i'm not a big fan of LEDs. only 12,000 lumens output? for a 1000 dollar piece of equipment. not impressed. nice thread though

If we were using a 120 degree LED, it would work very similarly to a CFL. Since we are using a 60 degree, the results we're having are more comparable to HID lighting, which is why we have sent 954W (3, 318W units) to Ed Rosenthal for testing against a 1000W HPS.
LED's are still new, and good quality ones are expensive, so the cost will probably be high for another year or two, until a lot of the market switches to them. It is one of the hold-backs, but after initial cost, you save money on bulbs, ballasts, and electric (not to mention any plants that were lost or damaged due to heat stress).
Anyhow, one person who I spoke to recently is interested in a 3-way comparison test using a 126W vs a 400W HPS and 400W CFL. I think it will make for an interesting comparison, but the Pro results will come from Ed.
I hope you stick around to watch them!

LED's aren't like HID, the lumens are completely different. A HID emits nearly all wavelengths of light, meaning that it only creates about 10-15% that's available for photosynthesis. So if you have a 80,000 lumen, 1000W Metal Halide, you only have about 8,000 - 12,000 lumens of usable light, the rest is reflected or unused by the plant. With LED's, you use the exact wavelengths of light that plants require for photosynthesis, meaning 85% - 100% usable light. Also, a 1000W MH, has a low life span, meaning that the lumens are going to drop rather quickly, unless you change it every 6-12 months. HPS don't fade as fast, but you still need to replace them once a year. LED retains 70% of it's initial output after 50,000 hours (6 straight years) of solid use. LED's certainly have a higher initial cost, but as I've pointed out a few times already, they pay for themselves quickly over time.
Anyhow, thanks for the compliment

So I added in the additional 756W of LED into my room tonight, and finally got rid of my last 1000W. The room now has 1512W of LED. One tray is full, the other is going to be filled soon. Anyhow, I figured I'd show you guys what this kind of setup looks like. I wish the pictures could display to you what I see with my eyes, but the color of light makes it difficult to get good shots. To put it simply, the pictures don't do them near the justice they deserve. Anyhow, check em out! I'm going to load another Volcano bag.

yeah , it means i agree with you
led's, NOW are not comparable to hps
i have witnessed many grows using leds and, i dont think that leds will every be on the level as hps lights,,, now saying that leds do have a purpose..... in the long run ,over, lets say 10 years led will produce maybe = to that, if not more then hps , but only after you factor in setup running cost - hps ( cooling fans, a/c units , outtake, intake, hoods , chiller's and all there parts ,pumps, ballast, the bulb itself and many more items) over ten years you would replace these item atlest 4 times, some of them way more then that. the replacement of these items will take away from your grow
- led's they will just run, run run and run prolly past the ten year
the major issue that i see with leds are they are at best campareable to CFLs,
what i saying is, what you can do with LEDs I'v seen done way better with CFLs. if CFL companys make a remote ballast CFL this would kill leds
but neither CFLs or LEDs are ready for commercial grows, and will never be ready for it
when it comes to big buds and 25 + plants its about penetration even if you just take a few plants 600w of hps is not = to 600w of led or cfl- now if your trying to grow a 1/2 lb or so then yeah led is King of the personal stash- but even then CFLs would serve you better. cfl are cheaper and can be found everywhere- now saying that let me pose a what if ; if cfl and led where the same price ( ofcourse the same watts) which would i say use and why--- leds all day long why because cfl still have to be replaced and produce way more heat then led--- now say that , let me pose another what if ; let say you could buy leds and hps for the same price ( ofcourse the same watts) which would i say and why--- well if were talking the same 1/2lb or so personal stash from earlyer then yeah i would have to say leds when it come to personal stash it the motion in the ocean that counts, but when it comes to large grow ops i have to go with HPS. size matters (right ladies) that folige needs good deep penetration
but after saying all of this- one last what if for you ; let say money wasn't a problem, you had like 250 million $, and growing weed was legal everywhere and a power bill was no issue and you could accomendate any type of setup any size what light would you use imgoing with HPS ALLDAY

So what happens when LED's lose their life or burn out? Do you just switch them to another purpose (side lighting, mothers) since it doesn't look like the LED's themselves are replaceable?
Something you might want to look at is you're shooting with a SLR or dSLR is manually setting the white balance. I have a custom white balance wet on my Canon for when I take shots of my plants under the flower lighting.
Those are some pretty bold statements and I think you're being overly pessimistic. Not that I can blame you considering all the LED hype we've seen the last five years but I can think two things however that are different.
1. I'm trying, and failing, to remember a time that a manufacturer has had someone like Rosenthal independently testing their LED equipment.
2. LED's technology has really changed in the last few year. 5 years ago the idea of a LED backlit notebook wasn't even considered because of the poor color levels.
Even if it never makes sense for large commercial grows, a lighting technology that produces less heat and uses less power than a 400w-1000w HID, with comparable results, will be a huge boon to home/personal grows.

Actually, in the long run LEDs will outperform HID lighting, but it will not today. Reason being PAR(Photosynthetic Active Radiation) of LEDs is very configurable giving 100% usable spectrum and when LEDs are released that do over 150 lumens per watt for their respective wavelengths -HID lighting should not be able to hold a candle to it. 8,000-12,000 usable lumens is a bit of a stretch but her point remains valid a large part of HID Lighting potential energy is lost in heat and tapers off as it reflects.yeah , it means i agree with you

When it comes to lighting for growing there are a couple key components that matter. Power of the light and spectrum. Obviously the more power the more the light is able to reach the plant. We commonly refer to this as lumens, however that is a poor choice. We should use PPFD as a measurement which stands for Photosynthetic Photon Flux density which in its most basic definition refers to the density of photosynthetically USABLE photons of light for the plant or how much light can the plant use to grow. The other key ingredient in lighting for growing is PAR which stands for Photosynthetically Active Radiation this deals with the wavelengths of light at which the plants WILL USE for growing. You know blue lights work well for vegging and red lights work well for flowering well this breaks down into several wavelengths.... I believe it is 420nm 440nm and 460nm for blue lights and we commonly refer to a mixed spectrum of it with a temperature of 6500 kelvin. For Red lights I think it was 600nm-660nm .... this all breaks down even further for CBN's, CBD's and thc usable spectrums.
Like I have stated earlier it is not ready to use on a competitive playing field w/ HID lighting today yet it will still grow buds, but I digress.

First off, there are TONS of different LED lights on the market, so which ones are you speaking of when you say that "they absolutely can't do what HID lighting can do"? The one Red, one Blue lights? The Red/Blue/White lights? The Red/Blue/Orange lights? The 5 band lights with orange? Lights from Theoreme Innovation? Procyon? Lumigrow? Who??? Each MFR uses similar specs, but they're all different. Different nm, different percentages, but most all the same intensity (120 degree lenses).
Unlike those people, these LED lights use 440nm, 470nm, 640nm, 660nm, 3000k white, and 740nm. Marijuana has peak absorption points for photosynthesis at 439nm, 469nm, 642nm, and 667nm, with peak points for carotenoids at 439nm and 483nm. If a light misses any of these points, growth will be decreased. If the light isn't matched to these points (like they used a 450nm blue instead), you won't have the same growth either. Likewise, if a company is using a 120 degree LED, vs a 60 degree LED, the one with 60 degree is going to produce better results, in a far more reasonably rated coverage area.
It's cool, the researcher who will be using 954W of our LED vs a 1000W HPS, will do a good job at showing you that 1000W of LED is more than capable of growing 1.5 - 2 pounds like your 1000W. In fact, we expect his yields to be higher than 4lbs with LED, but only time will tell. Stick around and watch instead of continuing to deny that there is any LED product on the market that con compare to a HID, because you sir, have not used them all.From the sounds of it, you haven't used any personally...
quit trying to sell your product. Its fucking annoying.
