Ok this is going to be a ramble , probly fragmented and misspelled so if your in a hurry scroll down..... I did some gardening last year and dived in the led tech without any knowledge really. I ran 4 x Mars 300s in a 39"x39".( they were cheap) It did what it needed to but my plants were stretchy, thin leafed, and I had to stake every single stem, the plants fell over from watering until week 4, not to mention dealing with heat issues as those bitches ran hot and they are red , white and blue lights only. Mission completed but definitely left me feeling I got 30 -40% potential. Lesson learned. Racked my brain for weeks on end whether to go Cobb, q boards, cmh ( all good options) or what next round. Talked to a bud out west he told me about an led he loves. It's an Agroled, Its Chinese made but he swears it's better than Kind LEDs. I'm like yeah.. ok bro. I can't find shit on the net about these lights except some hydro stores carry them and they are not cheap. I go to a store and check one out. Ok..this thing is built like a tank and makes Mars look like alpo cans, seriously. 8 fans, huge heat sinks and runs quiet and puts out zero heat. So I spend the capitol and pick one up the 576 full spectrum which runs 330 from the wall.. Now... my plants have thick stems, the leaves are huge and thick, tight node spacing and my tent hovers at 77 degrees no matter what.. it's like night and day.. I am not a rep for these guys but what a difference a quality light makes over those cheap imports. They get it done but you will be left with a sub par result. Ramble over.

Say no more, I get the picture...

You can go with 4 citizen 1212 and run them around 50w and that would cover that area pretty nicely. Cobkits.com has a good selection of citizen Cobs or you could bump it up to the 1818s if you wanted more light and dim them down. Most people aim for around 30-40w per sq ft. They also have some prebuilt cob lights there. But I'd you want to save some money you could definitely make your own just buy the light,holder, and heatsink and a driver to run them all.
If you have any questions picking a driver or which cob there are plenty of people to help.

Also the Vero 29s are a really nice COB and you can run them about 100w each. You can find them at https://www.digikey.com/product-detail/en/bridgelux/BXRC-30G10K0-C-73-SE/976-1584-ND/6557086

There should be more people like you in the world... It's sad that there aren't... Thanks dude for the help,it will come back to you!!!

You got ripped off hard bud

Considering my results, I disagree. You have used them before? I would definitely like to see pics of your results and specifications why I got ripped off. Thanks in advance.
Because you can buy a much more efficient light than that thing for the same price. AKA one that outputs a lot more light using the same power for the same price. 130 lumens/w for 5000k 70cri is bad. They dont even want to list the umol/joule output for that light because they know it sucks.


You're missing the entire point of this thread. ANY light can grow weed, and I agree that light is better than marshydro, but hardly so. I've personally grown rock hard buds, tight internode plants, with thick beefy leaves/stems under marshydro. Yet I would never recommend buying one.

Man ...I love all you guys throwing your input around as gospel. Saying its impossible is the same as calling me a liar. DO YOU OWN A AGROLED 576? My guess is no ,but due to your infinite knowledge you can correct me. This light runs at 60% and due to the cooling system its puts out no heat . It is barely warm after running 18 hours straight. I have one...I use one.. I know wtf I'm talking about . If you put your hands on the lights themselves the feel warm but not enough to put off and real heat threat to my tent.

My point of my post was to agree that Mars hydro sucks and there is better options out there. I gave my light as an example of something better. Is it the best, probly not but it works for me and that's all that matters.

So let's break it down, unless you owned one or had experience with this light, your talking out of your ass and my debate with you is over.

im not calling you a liar, just uninformed. What i say isnt "gospel" but it is accepted as fact

if there was a light that put out zero heat on the market every single other light manufacturer on the market would be out of business

the top top lights on the market are pushing 60% system efficiency. take some time to understand SPDs and efficacy you'll be better for it

https://www.dial.de/en/blog/article/efficiency-of-ledsthe-highest-luminous-efficacy-of-a-white-led/

This light runs at 60% and due to the cooling system its puts out no heat
so where does the other 40% go?

in any case if youre talking about this light im not sure where you got that it is "60% efficient" as they provide no usable photometric specs whatsoever

https://www.amazon.com/AgroLED-576-Dio-Watt-Full-Spectrum/dp/B076DHSF6Z

if i was taking a guess id say that would be lucky to push 45% efficacy but thats just a stab in the dark. 9 out of 10 times when manufacturers dont provide any specs its for a reason... because they are underwhelming.

I absolutely would not spend a dime on any fixture in 2018 that didnt either have:
a)an actual measure of photometric output in PPF
b) a simple design i can calculate myself to estimate efficiency (where manufacturer discloses EXACTLY what drivers/chips/currents they are using so i can go to manufacturer's datasheets and estimate efficiency myself)

Lmao..thank you, that statement wraps up. You just made my day champ. You sell Cobb kits = certified genius! Come by my place I show you all the proof you need. Now politely fuck off.

"Come by my place I show you all the proof you need."

a light growing healthy plants is no measure of efficacy whatsoever

not trying to be argumentative, what i speak is not my opinion and i am not talking down to you... it is the commonly accepted knowledge by which lights are measured

in fact i can prove that your light in fact does not create "zero heat". just wrap it in a blanket or duct tape all the vent holes shut. if it creates "zero heat" it should continue to operate indefinitely, right? as there is no heat to remove...

Sorry but Cobkits is absolutely correct. When you said your light puts out "zero heat", that is utter BS. It does indeed put out heat, it simply puts out LESS of it that the mars crap you had before. The fans spread that heat in a manner that makes it manageable. Thats all.

Then why does it need as much cooling as you say it does? All it means is the cooling in the fitting is more efficient but that energy is still going somewhere.

Tell you what, disconnect the fans and see what happens, then you'll see what is being pointed out to you.

And, sorry, but half a grand for that thing?

Like I stated, my room stays at 77 degrees, let's put it this way. The light itself is cool to the touch, the less throw off enough heat to keep the room at 77. Yes if you want to say leds throw off heat, yes they do, so does mine but this units does a great job of heat disappation and keep my room at nice level. So if you want to get technical it produces heat but way less heat than other units out there and I consider it very acceptable. Defending the light against people who have never used it and say it sucks is just as ignorant.
