If I ran my COBs at 1050 mA, 7 inches away I'd burn my plants.
LED bulbs for plant growth, which is best?

At the same amperage, yes, in output per chip. Im running an extra chip and another 100 watts on top of your setup for $20 extra though.

Yea, I did contemplate getting that kit.
My current setup is simply for testing. I want to compare these results to my prior experience with HID.
With that in mind, expand-ability was essential. I needed something that would have "room to grow".
The issue is the D and C variants. The lower voltage COBs don't have the same efficiency as the higher voltage COBs. Another reason I went with the more expensive option.
The SE was for plug-n-play. I'll be moving things around and experimenting with different spectrums at different wattages, distances and temperatures.
The kit felt too small and restricted for what I want, but that doesn't mean it is a poor choice at all.
I like that kit, I've been wondering if the heat sink would be enough to slap 3 Cs up there, but I doubt it.

Efficiency is the same. VxA=W. I could be wrong but i believe the difference is in the way the diodes are wired on the chip. The 70v chips just achieve the same output at a lower drive current but on the flip side demand more voltage. The more efficient setups are built using more chips @ lower drive current which is easier to do with 36v chips. Being able to run 2:1 chips per driver over 70/72v chips means you can distribute the intensity better over the canopy.

I know bro, it's like my plants went through light stress in the beginning, then said fuck it and became used to it. I'm pretty sure my yield will be effected by it somewhat, but my buds are rocks so I'm good!

For someone who pretends not to go with bro-science, you sure seem into it.
How are Vero's supposed to be any better than Citizen or Cree COBs. You think tiny spectrum differences really matter that much? That's 100% "bro-science" right there. Or is it the fact that they are cheaper for the same amount of light? Again, not very rational.
In fact hanging a load of smaller Citizen 1212's over you plants is definitely better than a few bigger Vero's. Better light distribution and more diffuse light coming from more light points is proven to be better.

You are that brick headed jackass. You clearly cannot see many people all disagreeing with everything you say. The rest of us have been posting facts and things that work and you are crying like a little bitch refusing to see the truth. I'm done with you. I tried to show you how Rapid was cheaper and your too thick headed to believe you may have been wrong. Then you go and show your knowledge by trash talking citizen cobs. The more you keep posting your B'S the more people see you for the brick headed jackass you are.
I'm done.
Peace out Jackass

At 70W the Vero29C SE will put out more light than the Vero29D SE (same chip as non-SE IIRC) @ 79W. Also, the D variant will need active cooling at that amperage as the C variant can be passively cooled. I am curious to see what they will do @ 1400 mA passively cooled.
I doubt you're yield will be negatively effected unless you have bleached the buds.
I can help you with that.
I have yet to see anyone of you asshats post anything quantitative.
Only slurs and personal insults.
Your posts aren't worth my time.
There are no "tiny" differences between Citizen and Bridgelux, they are vastly different.
Citizen COBs are marketed as entry level because they are entry level.
Ask RapidLED how Citizen compares to Bridgelux as I am positive that you haven't spent enough, or any time for that matter, researching the data sheets.
CREE has better numbers from what I recall, and the price shows it. Although, the increase is marginal.
I am using the Vero29C SE variant, not the weaker D variant. The efficacies are not at all the same.
You haven't posted a single quantitative figure in any of your posts.
Just Bro-Science, I'm not interested in listening to an immature drug addict. Especially, when I know I have spent over a month researching this topic.
With RapidLED the COBs would be $53 each with a smaller heat sink and you have to build it. My time is valuable. With TastyLED I get a bigger heat sink and I just have to wire it up, $60 done. That's worth $7.
The driver with Rapid is more expensive and not as efficient for what I'm doing. It will cost me more upfront and more to run.
RapidLED = $154
TastyLED = $165
$9 difference for a notable increase in performance and I don't have to build them.
Yep, it is cheaper to go with TastLED because I value my time and effort as well as flexibility. Why would I want to buy something I know won't fit my criteria and cause me to do more work, then eventually I will have to source a larger heat sink.. and then...
New players will jump at the chance to build their first array, I get that. After tearing apart cars/trucks/motorcycles for 15 years I'm a bit desensitized.
The only thing I want to do different is a stronger driver, I just don't want to burn anything as I know the Vero29C is intense. I could have sourced another driver but I was pleased with the product, price and customer service TastyLED provides.
Bridgelux > Citizen
End of story.

Three of yours @ 2100 mA would be about 240W, correct?
Two of mine @ 2100 mA would be about 280W.
You see, that's the stuff I looked at. These lights will find new homes over the next 5 years, they will also expand. If I purchased anything else I would have to replace it with these eventually.
Yes, for the extra $20 you are getting 100W more, actively cooled. Take that away as I don't want actively cooled COBs. That's when you will see the biggest difference.

The brigelux website lists the b,c, and d as all having the same efficacy @ 155 lm/w. Yes per chip, they will put out more light at the same drive current but the efficacy dosnt change.At 70W the Vero29C SE will put out more light than the Vero29D SE (same chip as non-SE IIRC) @ 79W. Also, the D variant will need active cooling at that amperage as the C variant can be passively cooled. I am curious to see what they will do @ 1400 mA passively cooled.

Indeed you haven't posted any quantitative data. Just some vague claims about "entry" level lights. You don't even quantify what that is supposed to mean.
If you are talking about spectral distribution differences then such data is completely impossible since actual data on what would be a "better" spectrum does not exist. Let alone that a pinch of red here and a dash of green there is going to make any measurable difference
It's 100% bro-science.
I have seen side by side grow reports and the result was that there was no difference between Cree, Citizen and Bridgelux. It's all pretty much the same light and you can run it at the same efficiency.

Are you really that dense?
Do you not read for comprehension?
You haven't posted a single factual piece of information. You haven't posted a single bit of quantitative data. What you have done is artificially inflate this thread with insults and senseless banter alongside your Bro-Science that no one should buy CREE COBs because Citizen COBs are just as good.
My figures, based on the manufacturers' data sheets, show Citizen to be weaker than Bridgelux and CREE to be marginally better than Bridgelux.
Somehow your Bro-Science says a COB that is half the cost of another one is just as powerful.
Next you'll tell me blurple panels are better than COBs.

*Sigh* @Enigma
Here is a quote from Rapid for 4 vero 29 c's, wires, thermal pads, wago connectors, power cord, dimmer, and wire and screws. If you get them to build you as a kit they discount it a bit and will sell it for 304.5 - 10% bringing it to 275$ shipped anywhere in the US.
Here is my Invoice to prove the kit comes as a discount at 305, Notice shipping had an extra 60$ because I live in Canada. We are discussing shipped in the US so I am leaving the additional international shipping charge out of the scenario.
Lastly here is a build list from Tasty with the exact same components except for the driver. Tasty doesn't carry a 2100ma Driver where Rapid does, so for more money you also get an inferior driver.
So for an almost identical kit
Rapid is 275
Tasty is 360
Rhaz has some great products and awesome kits that come with a fixture, you pay more for a service like this, You do him and his business a disservice by spreading untrue stuff around.
You call me a drug addict? Yet you cant even see logic and truth. I'm tired of your lies so put up or shut up. Here is direct prices from their sites.
You spent a month researching yet you are an idiot talking shit you know nothing about. I wouldn't brag about that. We called you on your BS about citizen chips and now you change your tune to say well Bridgelux is better than citizen instead of citizen is terrible spectrum and weak.
Lastly look how many different people all disagree with you, either 5 or 6 of us are all crazy or your so crazy you don't even know how bad it is. Don't worry the world always needs Ditch diggers, and burger flippers so you will be alright.
Smoke some more weed so you can relax and chill out.
