Cob style new lights? are they any good?

[Technique]

Can anyone tell me if these are any good?

http://www.aliexpress.com/item-img/...row-tent-grow-box-led-lights/1308397790.html#

they seem to be hgl sol and quantum helios but cheaper and much closer to me to ship.

 

[Technique]

or is this old tech and the bigger 3w single leds are better?

I believe verdantgreen is using a cob light but from a different company.

But the ones you show, works ok.

-there actually "newer tech"

-3 watt doesn't mean anything, as the cobbs are bunch of small watt led



-any good? no one can say, as there so new to market. I have one running flower, will tell you in 2 months.. haha


some positives are, cheaper production costs. no loss from lens

some negatives, chips get hot ( lumen loss ) , and spread might be an issue




can't say, as chips can vary so greatly.. kinda odd the link you show, the light has different chips from the top and bottom... honestly I would just buy a HGL, there cheaper then the X2 line, and have a actual warranty. whatever you do though, have fun. PS, you could build one for very very cheap....

No one can say?
Those leds work! I CAN say it....is the same tech of hgl sol, much more cheaper. (Do a little research, they are lots of success test even when they are new tech).
I have that led and they work.

^ if you have completed a set, please by all means post pics or experiences..

LED's need to be taken on an individual basis:

-color spectrum
-light spread / penetration / saturation
-heat management
-bin
-ratio of color/s



also no panel could ever be compared against each other, in it's truest sense.. but even then, all the above and more would make it impossible to say. Everything is theory until proven, and I have not see bud set from anyone using these..

do they grow.. yes.. but how well is the real question

 

[Technique]

Sweet thanks guys.

I havent been growing or keeping up with anything led for a long time, i think since the whole "led girl" shit on here and wasnt sure if the cob was actually newer tech or old.

since led tech seems to move so rapidly forward, who can keep up??

for 300 or so a piece i am keen to have a gamble, since they are identical. to the sol and helios, since both them units are made in china.

You must know a lot of people to state...no one can say.
Also if you haven't see it does mean that it doen't exist?
Everyone post on internet?

Sorry not time to post for you. All i can say is THEY WORK I have seen it. And if you check my post you will see one cob test that use same Everything but the cup reflection & the big lens. I use to be a led hater until I saw cob leds in action.

I reapeat do a research (outside this forum) ...SUN of HGL have very "similar" specs and they work, i know this as a fact...same manufacturer. (Do not think HGL is very happy for this tho). All i have is my experience so far, if you want proves, you just have to wait, they will come sooner or later.

is good to be skeptical when led grow comes arround tho. Me? 10 + year growing, 3 year of waisting time and money with leds...HID fan, until I saw COB led in action, I am changing all my setup from HID to COB Leds.

people on the internet want proof, not fantasy. no pic, no proof.

if you have, seen it with someone else. please tell us, gram to watt, what strain, what setup, what nutes, additives, how long growing...

also I'm not a LED hater.. far from it, if you've been around in here long enough, you would know I've built my own, and probably owned more LED's then most have. starting with the UFO's..



also, you might not know, but I have many many led in use, used many many LED.. to know, some are shit, some are not. these use new led's with new style of delivery, so call me skeptical, but I've been around LED long enough to know, it only works once you've tried it out, and your impressed. any led can grow, but not all can deliver the weight people are wanting.. there is still work to be done with LED ranging from color spectrum to layout to heat management....

 

[Oregonism]

I know this from looking around, COB's are drawing people in for their pricing and efficiency.

I don't have the experience, but I have decided that my winter project is going to be DIY Cob bars for vertical and top mount.

A TON of info lies in the Reef/Coral forums and thats where I have been reading for the last few weeks, following along. This is one of the main information bodies of Multichip LED lights and their interaction with living tissue, quite a different world on 1 hand and not quite that different at all, on another.

If you have patience seek that out, both DIY and commercial lights are used.


Personally, I would even go with the LUMIA right now, 5 channel 100w Chip, but it screams novelty Heated paperweight in 6 months.

[chileno1978]

Hey, just check the links, that's all
Also research, check what manufacturers make cob grow light (all from china, there is 2 or 3 only) and what companies sell it retail (like hgl) ... Do the math and check the specs.
Good you want proof but like the rolling stones song, you can't always get what you want... patience. Like I said, I was a led hater, only cob change my mind.

also, you might not know, but I have many many led in use, used many many LED.. to know, some are shit, some are not. these use *new led's with new style of delivery, so call me skeptical, but I've been around LED long enough to know, it only works once you've tried it out, and your impressed. any led can grow, but not all can deliver the weight people are wanting.. there is still work to be done with LED ranging from color spectrum to layout to heat management....

That was me just a couple of months ago, totally get it. (Arround 20 panels in the trash from last 3 years, love hid results no led can match it until cob)

2 already here using cobs (that I know of). Mine (signature) and https://www.icmag.com/ic/showthread.php?t=267243 both are cobs.
I have not finish mine, but with 30 days of flo I can say that so far is same or better than HID

I will have to say that your a great LED member, I look forward to many discussions with ya and I love your input "smart dude", however there is no manufacture that makes HGL products other that the HGL factory. And they do not make any other companies products.

I can name about 15 companies in china right now that all claim to make Hydro Grow LED lights. Why? casue they know hgl is the best. Noby wants a knock off pro-source light...Some may even make cheap knock off's just like most of china does. "like 95% of them" How many copies of the Hydro Grow extreme series have you seen to this day? about 50 or so???

With The SOL line you will notice no-one else has a square reflector. That is because through our research and development we found that a square reflector is much better at providing an even footprint in a square area. So why are none of the copy cats using a square reflector?

Because its patented this time around. Now all they can do is pump the unit full of cheap leds like normal "which will be easier to hide in a integrated chip" Slap a round reflector on it "no-one will patented a round reflector because this method is not too good"

Just turn to Leds for my test... I am quite new and donno much about it. (use to be a led hater 2 month ago)

So you work for HGL, get it. Guess the "smart dude" is you then...I am just a simple home medical grower (bit of an ass sometimes )
You have your own factory? where in China? interesting... I will have it too if the original manufacturer went direct retail.
I might have my info wrong tho. No doubt about it but (the mith grows). So you can say with absolute confidence that Shenzhen Houyi Lighting Co. has never manufacture any led for HGL? (just asking, really)

Why no one use a Square Reflector? easy one! is the only thing on the pannels that HGL can patent, would be nice tho to see a side by side square & round cup reflector. But I really do not think that will make the difference a real big one (IMO). Guess only time will tell.

That been said, I think HGL leds are AWSOME (but a bit expensive, been following them since Penetrators). Would love to have one to test it against the round cup.
So far I am very very happy with the ~US$250 300W cob led that I am testing.

 

[Loollo]

I'm testing cob chips. 50w 630nm for red and 10w 460nm for blue. I must wait 2 months to yield but till now the growth it's good !

Yes at one time they did make our x1 light. Promised us the world just like they do on there website, They continually would try to use cheaper parts even after repeated complaints. We bought our own factory after that and things have been so much better!

So yes they are 1 of many whom make a knock off light of the X1, they even took our label and try selling X3 knock offs which do not exist. Actually had a customer buy one of these thinking it was a hydro grow light, some guy in a hydro shop sold it to him. He had an issue and we sent him parts, they did not match. We asked to see the unit it was a straight knockoff with every single corner cut possible...

When dealing with 99% of china know that once they have a international consumers money they will disappear, there is simply nothing you can do even if you can prove every aspect of fraud they commit.

Why no one use a Square Reflector? easy one! is the only thing on the panels that HGL can patent, would be nice tho to see a side by side square & round cup reflector. But I really do not think that will make the difference a real big one (IMO). Guess only time will tell.

Well Your pretty close there. See the Square reflector is the only thing worth patenting. when trying to achieve a square even footprint like most grow areas, a square reflector does much much better at distributing the light. All those rounded reflectors will have a bunch of round hotspots and will be missing light in the corners between the chips.

We do not have to worry about people copying our diodes mainly because they cannot resist being cheap lol. That goes right along with just about every other element of our light to. 99% of these companies are using off the shelf spectrums and parts, no way would they opt to design a copper core heat sink or anything like that!

The drop in quality is also enough to beat the 10% different law in china, yea its different alright'

That been said, I think HGL leds are AWSOME (but a bit expensive, been following them since Penetrators). Would love to have one to test it against the round cup.
So far I am very very happy with the ~US$250 300W cob led that I am testing.

I Think if I found some people willing to try out the SOL light I could get a few out there'

 

[chileno1978]

Thanks for the info, really helpfull.
If you want a tester I am available respects meanbean!
I have the big lens cob & the round cup reflector cob...love to have the square one....send me one and i promise a side by side

 

[WeedIsGod]

Would get one like this:

No glass lens = greater efficiency.

Square reflectors could be cool.

 

[chileno1978]

Have them, not test yet tho

 

[Neekz]

Lol "off the shelf spectrum"... Umm I know for a fact those "Copper core" heat-sink's are off-the-shelf from PC CPU cooling supply companiesc(Not even the same thickness as most CPU counterparts...)... Not much more R&D than getting them to make surface area larger/flatter, and even "your" supplier has a hard time doing that (Other member's have reported repeated "light drive" failure's due to the sink surface being flawed and warped.). He modified it himself and improved longevity with a little effort. For a $2-300 mark-up, yall can't polish up the corners a bit, jeesh?...

I honestly don't see much difference in part's quality in between "your" 336X-PRO and product's by say Cidly or Bysen, beside's the latter being seemingly better finish and easier modularity. Heck even my china veg panel looks on par and uses a better sink than what I have seen in HGL's offering's...

HGL

The unit I got from China uses a square finned aluminum sink nearly the size of the entire housing kinda like this, only 300mmx300mm.

I guess you can be proud of getting your guys logo on everything lol, since you managed to have them even etch it on the sink's that aren't surfaced properly...
