re: LED GROW TEST. 126W hydro grow led VS. 180W

lol. honstly i dont let anyone tell me what to do or what i can say on my threads unless its a MOD. i feel either company shouldnt care what i say about future test because no one has one this test yet. No need to jump the gun. given this is my first grow with the 126w and i dont know what it can do? but this is sertinly not my first grow with the 180w. and i do know what it is able to do. so i will be dame if i get told what i should say by a company that hasnt won anything in my test yet.

You keep it real and I like that. Your Journal and that's that.

How can you argue about a future grow?

cant argue about a grow that hasent even been won by anyone yet.lol.

this grow isnt over untill it hits my scale with pics

re: LED GROW TEST. 126W hydro grow led VS. 180W

anyways heres the companys name i am going to test out Grow Led Hydro i know its funny both companys have the same name but backwards. they use 9 spectrums and use 3w leds instead of 1w like PS & HGL.

this is going to be a weird test since evey companys claims that the 3w led arnt better then the 3 one watts leds. but this company claims the 3w is the way to go.

I'll make my comment and then turn the thread back to you Irish

9 spectra, yet red, orange, yellow, green, blue, indigo, and violet are what we are taught in school, and that's only 7. They state they don't use green, so where are the extra 3 spectra? And why would you want 9 spectra anyways? Doesn't that kind of get away from pinpoint accuracy that makes LED's so viable? 9-band is probably what they mean to say, but even then my previous comment still stands.

Since you decided to list the company, this means I get to dissect them SCIENTIFICALLY, and realistically online. This has nothing to do with opinion, and by now Irish you should know a thing or two about claims lol.

So I'll start with the 3W LED argument. I don't need to "claim" anything, since I always back up my statements on this subject with data. I've posted this many times before, but here it goes again (feel free to call Cree or Luxeon to verify my statements):

1W LED's are the most efficient light sources when it comes to lumens per watt. 1W LED's have the same amount of "light energy" as a 3W, meaning that there is no difference between the two on how far they can carry light energy (penetrate). Now here come the facts:

Sent by Bernie Eshel at Cree:

"Hi Cammie
It was nice speaking with you on the phone earlier. Below are some ideas on the costs for the more cost effective LED solutions from Cree.

XRE RED 40 lumens MIN

All ratings are at 350mA
700mA you can multiply by 1.72

B"

1W: ::: Edison Opto - Products :::

3W: ::: Edison Opto - Products :::

Now, look at the first LED on each link: 620nm~630nm. For 1W, your output is 45lm at 350mA. For 3W, your output is 80lm at 700mA. Now, I trust Cree to tell me the correct multiplier, so let's take our 1W and ramp it up to 700mA. 45lm x 1.72 = 77.4lm. So, even if we leave the 1W LED's at 350mA, 3 of them still come out to 135 lumens, which is 41% more output than the single 3W at 80. So do you want to trust claims or data?

MOVING ON: Coverage Area

This company claims that they use 60 degree LED's (hmm, wonder where that came from lol). They also use the same casings as I do: 126W and 318W, they simply load 300W into the 126W panel and 600W into the 318W panel. Irish, you've already stated elsewhere (and maybe here) that our unit is dead on with the 2' x 3' coverage area listed for our 126W. That's 2' from the 12.5" section, and 3' from the 19.5" section. Keep that in mind for what's coming up.

The company you referred to lists a 6' x 8' coverage area for their 300W light, with 6' x 4' for "core saturation" (meaning that bright spot from the light). Our light using the exact same casing, and 60 degree LED's has a "core saturation" area of 18" x 30", so how in the world can you create a light with literally 3x the coverage area, when you have the same space limitations and angle limitations as us? It's not possible. The company proves this by contradicting themselves on their own page. When you look at their 600W light, it states the core saturation area as 6' x 8'... So how is it that the core saturation area just expanded another 2 feet width-wise, when the 600W and 300W casings are the exact same width? Scientifically their ratings are false.

MOVING ON: Spectrum

Like I covered above, if using 9 spectra without the color green (which is scientifically impossible) then you're operating the unit like a HID or MH, instead of pinpointing the light wavelengths. We know plants absorb blue and red light most efficiently. We also know that orange has little to no benefit on plant development (in my testing it actually caused issues with my plants like leaf curling, dying, etc... when placed too close). This company refuses (like so many others) to post the nm's they use in their product, they just want to you trust them on it Here is what they do give you though (which also disproves the whole 9 spectrum thing) on their site:

When I saw this graph (with 6 points, not 9), it reminded me of another company I came across a while ago: Growitled.com - LED Grow Lights Red, Blue Tri-Band Spectrum design. Newest technology available. , as they use very similar specs. The specs they list are 730nm, 660nm, 630nm, 612nm, 462nm, and 420nm. Even without these specs (just by looking at their chart) you can tell they use a 660nm, 620-630nm (too close to orange to be 640), 612nm, 420nm, ~440nm, and 460-470nm, which is still only 6 points and 4 spectra (violet, blue, orange, red). So, where are the 3 that are missing?

FINAL POINT:

So in the end, claims are simply claims. I don't need to test against their light to know where it stands scientifically, as I've already pointed the information out. So anyone can make a claim, but how many people do you see out there like me backing it up every chance they get?

re: LED GROW TEST. 126W hydro grow led VS. 180W

wow you take that stuff to a whole new level.lol. is it posabil that they get more foot print buy using 3w leds because their briter? half of that $hit you say about nm i dont understand since i belive no one knows the exact nm MJ wants or their would be some crazy plants indoors that we get out doors. am i wrong? do you know the exact nm MJ using or are their some missing. also on the foot print dosent it work like this on ur light 2x3 so that means 1.5"x2 on one side and 1" on the other side x2 witch = a 2x3 area right always wonder how they mesure that stuff. i use to think it was 2' on both sides and 3' on the others.

anyways thanks for putting 10 pages of info about the company i am going to test on my thread.
you are somthing els, i just hope all this work you do on riping apart other companys you put into this light in my room. i can see that every thing in ur house must be led.lol.

but for real i am too dumb to read all of that you posted i start driffting off looking at my hand and keyboard thinking what i wanted to eat. good old weed

Buhhh there ya go Cam, Nice work on the "mini spec sheet" on LED, musta took you a while to make, with the pictures n Nat!
At least your getting an arguable response LOL!!!!!

Irisboy, I like the test I am down to see what happens, not that I don't have my favs! I wish I had a journal of my first led grow to look back on!

Nope, 3W LED's don't emit a wider angle if they use the same angle silly. The spread is the same. If their board was twice as wide as mine, I could see it being possible...

As per the exact nm's that MJ uses, the specs I post (439nm, 469nm, 642nm, and 667nm) have only been validated by other growers online, never debated or argued. They are the exact points at which Chlorophyll converts light into plant energy most efficiently. Carotenoids use 439nm and 483nm. There are other tiny accessory harvesting pigments to carotenoids that account for maybe 1-5% of photosynthesis, but these get hit with the white from our product as they tend to fall in the green/yellow/orange range. Oddly enough plants do absorb green to some extent, although my research regarding that is on my other computer (in Cali right now).

Our unit is 19 x 12.5", the footprint is 2' x 3' (box). So the light extends about 6-8" in each direction from the actual unit itself.

ANYHOW, Let's get back to your grow ;)

thank you for that info. you ever plan on using UV in ur lights to help resin? so ive read it dose?
i can see leds is ur life and u study the hell out of them so if i ever have a question all besure to ask you.

thanks!

ps. i am not realy a prick its a medical essiue called a$$hole sindrum, my girlfriend hates this medical issiue i have to, she will probley leave me and take everything too including my led lights and plants.lol.

thanks for the help on the leds

Wow, your journal has turned into a mass of information. In the end not of that information is going to matter. The proof is in the pudding and your journal is going to show what works best. So keep up the good work and will be watching for sure.



Great journal, great job..

re: LED GROW TEST. 126W hydro grow led VS. 180W

hey irishboy wow its getting intense in here that's cool to see things get sorted out. from what little i have read about leds it seems that the flowering stage is the tell all about performance. i glad there are actually affordable leds that seem viable to the average grower i think back a couple of years to when people laughed at how they performed especially in 12/12 and how anything worth while was like 2grand.
so how are the plants doing any pics on deck?

btw i looked up those airpots that you and andy posted they look sweet im thinking about getting some for my regular garden thanx for the info guys

On a side note. Hydrogrow, I think your are doing you and your company a disservice coming out so aggressive in this journal. This guys just doing a test and in the end it does not make too much of if difference what you say. He doing a test and if yours is best it will come out on top. Its a simple as that.

No offense it just a thought.

I know we've been over this before but this is a good time to clear it up.

Did you say within that 2' x 3' section had a sweet spot?

i agree 100% with you. we can talk all we want and make claims but nothinging mattes untill those plants are pulled and put on a scale. its all about the buds.

ya it was getting intense in here but alot of that was my smart a$$.lol and alot was just joking around talking $hit. but i agree with you the flowering stage is where you can sperate the led lights from each other and find out witch ones for real. i cant wait to see what happens.

i wanted to wait on the pics untill sat so you guys could see a big diff since last time.

re: LED GROW TEST. 126W hydro grow led VS. 180W

and to all that are watching this thread, thanks! you guy's rock. you all have treated me with alot of respect even through i grow with leds. please dont let this little set back last night change ur minds.

me and Led girl have always gone at it and have had our differnces since i first started posting on the fourms. some of you that have been following my old led growes with pro source know this. its just how it is we both have strong opions about differnt things and dont get along alot of times.

this is the main reason i did this test is to see if all this talk about how her light was the best and pro source [wasn't] this and that. nobody at the time knew who to buy from, then all the led growers started spliting up and taking side between the two companys, somtimes it was a mad house. so i thought about it and said fu$k it! both companys want to talk a big game? then lets do it, put up or shut up. so i decided to find out first hand with my own eyes.

put now we will find out the truth, and i will know where to send my money for more lights if they work at all or els ill just fire up the 1000w hps and deal with all of that heat.

This is a great journal and it has a lot of information on here that is very helpful. I must disagree with your comment on Cammie doing her company a disservice by posting all of that info. Because this is after all a journal to compare these LED's and find out which one is the champ and which one is the chump. Anyone seriously researching LEDs to purchase is looking for data and thats what she provided.


Irish

Have you noticed that the 180w stresses your plants at all if they are less then 6 inches from the tops of your plants? The reason I ask is because I have 2 of their 90w models and I think I have heat stress on the tops of my plants. I let them get about 5-6 inches from the tops and maybe I shouldnt have.

Before I ordered my LED's I did a lot of research and came across the Spectra brand LEDs. I was pretty impressed with the claims so I contacted them and started asking questions about their lights. They wouldnt tell me which LED's they use or the exact wavelengths of their LEDs which made them start to sound like a snake oil salesmen (aka most LED vendors)... when I asked about the warranty (30 days) I took them out of my favs and didnt bother to find out more. I couldn't see spending 2000 on lights that only comes with a 30 day warranty. If they are willing to give you a free light to test against other LED's then you must be talking to someone with some clout. I would suggest to them that they should warranty their work for at least a year. I might have purchased their lights instead. They were one of the first LED vendors I found and I hadn't realized how flaky most LED vendors were yet.

General rule is if a company has a warranty <1yr = they have no faith in their product or it is malfunction prone

1-3 years = good product, should last ya a while but extensive durability under everyday use havent been clinically proven.

5-10 years ... this company thinks and believes their product is the sh!t, and if one happens to trip up they have faith their second unit wont

There is a sweet spot MeanBean. I am not sure exactly what it is, but the unit does a good job at covering a 19x12.5 area, which the size of the unit itself. Not speaking for Cammie, but that would be my guess as to the sweet spot. Give or take.
