Mars-Hydro LED Grow Light Discussion

Confused by your comment about 3watt LED's and hopefully in the future the LED's will be 5watt. The Mars II are supposed to be 5 watt leds? Maybe I'm missing something or you know something I don't?

I totally encourage the development of LED lighting in fact it will in the future be the way to go. I have been working with manufacture's in china on development of the lights for about 4 months. There are still a couple critical areas that need to be addressed that to my knowledge just about every manufacture there misses. Remember when it comes new product designs in china as soon as 1 guy does something they all do it. I have catalogs and pricing from no less then 20 manufacturers in china that are all basically doing the same thing. The fixture casings are different but the technology and applications all mimic each other. The LED chip sets currently available are peaking at 3 watts the lumen to watt ratio is not that of HID and the cost per watt is outrageous. We spent 6800.00 lights with freight on 9 900 watt fixtures to lamp a 10x15 area that was lights only at 50 watts a sq ft vs 1600 cost of 8 HID fixtures and cooling and bulbs 2 per fixture MH and HPS. Like I said I encourage the continued development of LED lighting. There are some issues with wavelength and the uneducated perception that the wavelength can be addressed with a single application in the 460 range the 630 range as this is the focus relative to the PAR. The basic facts being that necessary wavelengths are missing." YES" THESE LED'S WILL SUSTAIN PLANT LIFE! They will grow you a crop. They make your grow room look night club cool. New genetic material must be used every time to avoid the degradation of overall health of the Biota as these lights are missing key wavelengths necessary for permanent sustenance. Clone stock begins to suffer over time if the mother is kept under LED's as well. We ran the whole controlled program. I am certain you will get a harvest out of these lights. I am also certain they will not sustain healthy plant life with out additional spectral exposure for a long period of time. In our experience the first harvest with fresh "germplasm" was the best. I have about 280 PAGES on the Pros and the cons relative to this topic for anyone interested. YES they are the" HYPE" right now I am well aware, We hyped 6500 dollars into the concept to figure out we need to be involved in the design process. In fact I think Sarah's company might have even contacted us regarding manufacturing lights to our specs. I wish everyone the best with there LED grows it is different being around the isolated spectrums. I am anxious to here others experiences and how they work out over time. I am hoping that we will see the 5+ watt LEDs soon and I pray the price comes down on theses so they are affordable for everyone and they become the primary source of lighting for gardeners as there carbon foot print is much much smaller then that of HID's.........Always taking giant steps to leave smaller footprints.

Hi EyeDoolt!

I too was confused my that. The 5W LED's in the Mars II units are draw at 2~2½W, so maybe that's what he ment. Although he said he hopes to see 5+ W LED's in the future, I already saw some DIY guys using 10W+ LED's in their lights with great succes. Am I allowed to post link to threads in other forums? There is this guy named Mr. X that is using (seems to me) DIY light, and he is getting 2.14 grams per watt. Very good result i believe! do a google search on: "grams per watt led" and you will find it to be the first result. :welldone:

These are the specs used in the light:
30 led Cree XP-E red 630nm.
15 led Cree XP-E cool white

- Now I know LG LED Solutions Limited do not use Cree LED's, but it shows that add'ing white will add great results. Even other growers in this thread stated that Area51 is the best LED grow light atm. and it has only deep red and whites as far as I know?

I just need to see some data on those 2500k~3500k and 6500k~7500k whites from LG LED Solution Limited to see in what wavelenght where they peak.

Best Regards

You can see the canopy, the led plants are neck and neck with the hps side,
the first 2 plants in the room get no hps light and the quality, density and trych production are night and day better than hps nugs, I spent just as much as you for my 4 area 51 lights and I have no regrets, I ve grown comercially with hps for over 10 years now and I cant wait to get rid of the last 3 hps in my room. Yes they re are ALOT of fly by night Led companies out there,they are the companies that gave led's a bad name but there are also good led companies out there that can and do test on MMJ.Sara's company isnt legally allowed to test on MMJ in China, its illegal there, so she was smart enough to join a MMJ forum to get us to test them for her. She's sending me 2 Mars II 240 x 5w with the same spectrums as my Area 51 panels to test. I ve been growing CH 9 Jack for over a year under these lights and it is still just as good, just as potent, just as frosty and just as dense as the day I started growing it, from my experience there is no degredation,at least with my panels, my yields are still getting better every round.

Here are the ratios for my 300 x 3w Area 51 lights that use 3w Helexion diodes, they are older models before they started using Cree.
Natural white-100
Red -120
Deep Red -70
IR -10

I never stated that Area 51 lights are the best because ive never tried any other companies but the results I get with them speak for themselves and I havent come across any other growers using them that were unhappy, all I know is the spectrums they use work great:)

Hello Craddady!

Thanks for the answer. Although I am not sure I understand what you exactly meant ^^. I have already talked with Sara via mails and she already gave me a good price for the unit (even if I was to customize it myself) :high-five:
Sara told us that they do not do research on MJ plants. Therefor I am asking for the people's advice of those who have grown with different variants of LED lights (Different types of panels with different ratios on the nM). I saw just earlier that Jon planned to/had already -ordered two units of Mars II with Area51 LED ratio. This is what I am curious about. I want to her more. :hmmm:

Also i may need to add, that this has nothing to do with their Mars II unit not being able to produce some neat buds. I already saw what it can do. It's just that if there is any secrets that to this day has remained secret. Please do enlighten us all! If there is anyway to get the extra bang for the buck, then why not do it I say? :dreamy:

It's getting late. I better get some sleep. I am hoping to get this thread going again and see some answers before i make the purchase.

I chose the Area 51 ratios because I love the results I get with my lights, I'm not educated enough in this subject to try and guess what spectrums might work better and why would I? Area 51 does extensive testing with they're lights on MMJ, just about every member of that company are card carriers including the designer Jeff, I ve been following some guidelines he gave me and I couldnt be happier with the results im getting now. Theres a misconception that if you grow with led's the room has to be warmer,he told me this was wrong and to try running my room at 72-75 degrees datime and 68 degrees nightime, just that alone has made a huge difference in the quality and yields of my grows, defoliation is another one, His best results were with minimal defoliation, indoors your always going to have to remove some leaves but instead of "defoliating" spread the plants out to get light down to the lower branches, ever since I ve tried these 2 changes in my growing style my yields and quality have been getting better and better. I guess my point is theres alot more to it than just getting the spectrums right, room conditions play a huge part as does manipulating the plants,the skill of the grower and the willingness to try different tecniques also plays a part, I had to learn how to grow with them, ive been at it over 2 years now and im still learning little things every round that have positive and sometimes negative affects on my grows.

Hello Jon,

Thanks for your replies. I am sorry if I may have expressed myself in the wrong way, when I said you claimed it to be THE best LED light. What I ment was simple that you vouched for it. :thumb: Would you mind telling me the ratio you are using in the LEDS in your Mars II's with the Epistars Diodes? DO you happend to know where their white diodes peak in wavelenghts? I havent been able to get an answer from Sara on this one. :hmmm:

Goodmorgen everyone! :yahoo:


Hello Output,

I am going to let LG LED Solution do the customization of the light. It's will indeed cost me some extra bucks, but if I get better results i think it will be worth it. (We are not talking a whole bunch of extra to pay) As far as I know, there will be the same 3 years of warranty with my light if I was to get them to customize it. (Please correct me if I am wrong here Sara)

Best Regards

Perfect. That's the way to go from all I understand.

I'm excited to see how they work for you when you get them.
 
jon705 said:
Im sorry bro, I gave Sara the same info I posted here on my lights, she just forwarded the info to her engineers.
my lights are 300 x 3w
100 natural white
120 red
70 deep red
10 IR
Im way to medicated to figure out what the ratio is right now lol

Sara has been pretty busy but im sure she will answer your questions on wavelengths here when she see's it:)
Click to expand...

No worries Jon! I will just talk with Sara as soon as she gets the time. There is no rush. I did the calculation earlier (before i got to medicated myself :lot-o-toke:) If anyone wants to know the ratio it is: NW 33.3%, Red 40%, DR 23.3%, IR 3.3%.

I will make sure to give you guys feedback on the light. Though I think that I will be using close to- if not the same ratio as Jon ordered, and I am possitive that he will get his lights before I do. So you might as well sub' his journal (if he is to make one ofc.)

Hey Jon and Love Doc, I'm about to be putting in a fairly big order from Sara and wondered if you guys think I should custom the spectrums/ratios to those or maybe try and stick with what they have. I'll only be using them for flowering.
 
Curso seems to be loving his light EyeDoolt and its factory specs, im going with the specs I know to work well for me, I dont see the point of green led's for one thing and I think the blue should be replaced with natural white, theres plenty of blue in natural white, ive vegged with my panels they work as good or better than mh imo..actually this is all just my opinion I have nothing other than my results to go on here and im happy with them:)

Hello EyeDooIt,

If I were you I would check out some of the journals made by people that are using lights from LG LED Solutions Limited. I have seen good results with manufacturies' normal ratio on the Mars II units. And their older reflecter unit seems to do alright too, although it does not have as good penetration as the Mars II, it does not have licens either, which gives it a higher lumens output per watt (correct me if I am wrong please). But it seems to me that the new COB units are missing some wavelenghts.

My personal choice lays with the Mars II unit. I just need some sort of chart to show me where those white LEDs peaks in wavelenght before i can make my final decision. :dreamy:

Would that be your old A51 or would that be with the unit your received to test for Sara? (which one was it again?)
I do not believe they use natural whites. It's either warm white (2500k~3500k) or pute white (6500k~7500k).

Best regards

One could buy a «standard» LED panel from Sara and complete the spectrum with some CFLs warm white/cool white?

I'm actually thinking of doing that.
I do have faith in TopLed engineers and looking as other journal, the Mars unit seems to be doing pretty good.

your right lol..its cool white not natural white, my bad:)

Jon would you happend to know the difference between the pure white and the cool white ?
I did a little research and as far as i can tell 6500k~7500k would peak in the blue wavelenghts. I found this info at some other forum. You might wanna check it out:

"there IS a relationship between a colour temperature and the peak wavelength in its spectrum. It's called Wien's law.

Wavelength (nanometers) = 3,000,000 / Col temp (Kelvin).

So at 4,500K, the peak wavelength is 666nm (red) at 6,000K the peak wavelength is 500nm (bluish green) and at 7,500K the peak wavelength is 400nm (deep blue)"



Ok, given 'weins law', and knowing the wavelengths that chlorophyll A and B function at, we can figure out the best color bulb to use

Chlorophyll A: absorption peaks at ~440 nanometers (blue) and ~660 (red)
440 nanometers = 3,000,000 / 6,818K
660 nanometers = 3,000,000 / 4,545K

Chlorophyll B: absortion peaks at ~470 nanometers (blue) and ~640 (red)
470 nanometers = 3,000,000 / 6,382K
640 nanometers = 3,000,000 / 4,687K

Jon I don't believe the Mars II 240x5w that I have has any green LED's in it? Or it something i'm not seeing? I can see what you mean about some more whites though.

Hello EyeDoolt,

You are right. The wavelenghts used in their Mars II units are:

430-440nM purple
450-475nM blue
610nM orange
620-630nM red
650-660nM deep red
720-730nM ir

I do not know if I am allowed to tell you their ratio. But there has been posted some pictures of the light panels where you can calculate their ratio.
