MCOB...I want to let you in on a secret...now don't tell "those people", but this is really not the place for snake oil and smoke and mirrors. Most here are going to want a brand name cob, some real spec sheets, and a PAR print. Otherwise a new side vent and a zoomy little video isn't really going to generate much excitement.

Sketchy ... Like to know components used .
Spider web vents are kinda corny.

I already know the specs for the current products + new ones. They don't list them on their site because you can request the ones you want and they can customize it for you (wholesale orders). They don't do so much 1 off selling as their web prices will show.
It is funny to me that you guys think the lights are too good to be true. That just tells me that I'm using the right products and don't need to switch to something else which is fine by me! And yes I realize people on this forum are DIY lovers and not the people they are going after. DIYers know grow lights better than the average person and know they can get them made for a fraction of the cost + know what works better - some of the time.

NO ONE thinks your lights are too good to be true...........have you looked at the grows around here? blow away all those videos you posted.
Again what chips are being used?.......osram/cree/b-lux/ledengin/epiled/epistar/ generic encapsulated leds that PRC pumps out by the thousands a week? TELL US, looking at the price point most of us already know the answer.
125w top bin osram fixture(zelion) goes for $900 btw,lol

LoL, either you have no logic capabilities in your brain, or you are still trying to sell to those lacking logic.
Every single claim that says their light can match or outperform 2x the watts in HPS is and has been a lie to this point. The most efficient LEDs on the planet at this point are just under 1.5x as efficient as HPS. So if you replace 3000w of HPS with 1500w of LED, you will always, 100% of the time, be reducing the amount of light in your room.
Everyone wants to know the chip specs because you could have a 70 lm/w chip or a 100 lm/w chip, or a 160 lm/w chip, or a 180 lm/w chip, or up to about 220 lm/w with the most expensive fancy setup possible. Anything under 150lm/w is a total waste of money as they are less efficient than HPS and cost more.
I would bet money that these LEDs either are less efficient than HPS, or very very close in efficiency. These like 80%+ of LED grow lights are a SCAM/RIPOFF.

Hey MCOB,
If those lights work for you then that's all that matters. I have certainly seen great results from almost every kind of light you can name.
The thing about this particular sub-forum is that these DIY guys know what they are talking about -from their experience with building lights. They know what the best components are and where to get them. Some of them have even started their own companies as a result of answering the call for better, safer, more efficient, etc. lights that would stand out in the ocean of otherwise cheap, low-quality, mass-produced, "blurple" (blue & purple) "custom" spectrum lights. It's kind of an island here that way.
No one is going to care what light you use -as long as you're not here to try and convince people that your light is superior to other lights or that it has advanced technology, etc.
The general advice of this forum is to look for lights that incorporate well-known and tested components -like Cree, Vero, Osram, Meanwell, Ledil -as well as lights that post the outputs and efficiencies. In all honesty, the charts and PPFD values and all that are lost on me, but I think it's a safe bet that if you can get a fixture that is built with the aforementioned components, then it's very likely to be a good light.

They're just another low cost LED grow light. You can buy units just like that on Alibaba for $170 if you buy quantity. Obviously it's not going to be high quality components for that kind of price. I realize you have to try to sell product, just probably not many takers on this forum. I'm sure your stuff is as good as Mars. Just that Mars isn't very good either. Your units could have cheap drivers that don't power the MCOBs reliably. We have no way to know what's in that thing.

There are plenty of these " psuedo COB " lights that are coming out. Mostly hopping on the COB bandwagon - by name only.
Here is another questionable unit SIMILAR to MCOB .....
No description , power draw , led ratings , construction features , etc.
There are 2 types of full spectrum COBS, one that is composed of many different colored LEDs mounted on a COB. BUT have been proven to fail as each diode has different power needs and are all being driven the same. One goes they pretty much stop working
The other is a phosphor coated LED, where all diodes are the same. Even a MARS Light technically can be repaired by a DIY person by replacing the defective diode. 3-5w LEDs are easily available.
This particular RAYSACE light makes big claims with a " no info " video . They claim 15% more productive growth but fail to show how. These cobs are also BLURPLE in color and claim 800 watts !!!!!! Even the " reviews " seem questionable.
I messaged them for a little more spec info but have yet to get any response.
At least people know that even a Mars Light , Apollo , G8 can grow , because you can see actual grow videos .
I wouldnt buy a car claiming to be the fastest without checking out the engine.
Just sayin

There is facebook.com/growthstar and a 550 watt scorpion cob vs 1000 watt hps (same strains) with photos on the www.cobgrowlights.com blog
I use both scorpion and spider right now and the spiders work well. The chips are bridgelux/epistar.
Theres the option for the scorpion with more white light but my plants under the growthstar spider are growing best.
These are the two results of tests I ran in December~ the third one was an option they gave but I didn't go with it. The ones they sell on their website are the cheapest priced units. They have 5 or so tiers on the chip quality and so on for wholesale buyers.
I will say it one last time, if you want a certain chip/spectrum, they will do it if you buy wholesale.
If you have a problem with the grow results photos and videos and/or don't buy in wholesale quantities then we aren't even on the same floor.

I can buy those ones resold by Raysace for less than 1/5 of what Raysace sells for - with better specs. They also have the phosphor coated versions tested and out. I have all the photos specs and everything man...There are plenty of these " psuedo COB " lights that are coming out. Mostly hopping on the COB bandwagon - by name only.

Raysace and the manufacturers both advertise the total not actual draw. Those Raysace guys are just a reselling company that does look like a pump and dump. In fact there are many dozens of different sellers that sell that unit from the same manufacturer. Raysace just does a lot of spec marketing to justify their pricing.
I do know the manufacturers as I once inquired to order 40 units from their USA based warehouse. Growthstar tried to make those lights work last year I think around november-december by improving the specs and running tests but the units they got were bad man. Lots of manufacturer defects even when the Chinese manufacturers claimed the defect rate was nonexistant (salespeople ffs). So Growthstar eventually pulled them off their website and gave the guys that bought them refunds.
Raysace are run by a chinese company that resells the products in the USA with pretty misleading marketing practices. So if you do make a large order and you get a bunch of junk - good luck trying to pursue legal action to get your money back. Don't buy from the raysace company for those lights. You can find the same lights on amazon or ebay under different names for a lot less in a pinch. I'm pretty sure the specs are fake though. Never tried them myself...
Myself, I prefer to deal with a company that doesn't sell their products solely based on the specs alone but emphasizes photos and grow results. I do request specs since I order bigger quantities and they provide it as a result. If specs arent on their site or they won't give them to you because you are just buying 1 unit then who cares don't buy from them lol. There are thousands of other places to go and buy a light or make your own.
Anyone company can bullshit their specs but pictures and results are harder to argue with. DIY is a headache to deal with and quite frankly a waste of my time + not an option for people that care more about getting a good harvest than saving a few bucks and not being able to sleep at night wondering if the DIY units are going to fail.
Anyways, there are probably better lights out there but I'm slow to change. I'd have to be completely blown away by something new to 'see the light' if you will.

Sounds like a better company than many. Growing "bleacher" style was a great idea to get more plants in a small space. You could make lights using Bridgelux V22 COBs. They're only $15 each, good lumen output. People are wary of the mixed MCOBs. They associate them with cheap quality.

Bob, can you share a link to a guide that you recommend for DIY? I'll test one out sometime just for my own entertainment. $15 is nothing compared to the tens of thousands I spend every few months so I'll give it a shot.
And to those who think I'm trying to promote something - not quite. I dont get any kickbacks for posting these things other than learning from you guys about the DIY LED space which I don't spend a lot of time in. Most of my colleagues buy USA made lights for their grows and laugh at me for not doing the same.
Thanks again for the info.

So you admit that you are affiliated in no uncertain terms with manufacturers and yet you are not willing to tag yourself as an advertiser.
Guess what feature available to me from riu I just used on you and your overly text heavy diatribes?
