I don't think they do either. I finished registering earlier today and was able to view my order. Status says completed and last shipping time was sometime yesterday so its on the way.

Yeah I chose priority so I should be getting them this week then. I think it was you I saw posting on the driver I chose that's would made me look at it. How big of a heat sink do you think I'd need to run 4x Vero29 at about 2.1A with just passive cooling, a inline exhaust fan, tower fan inside the tent, and a fan sitting outside the tint blowing air inside through the mesh or would it be best to run active cooling with that many watts? When do you think you'll assemble your next build?

MrFlux runs in parallel - you'd want to test vF of each cob to make sure it was the same though.
I dont want to keep postung about vero cobs in cxa thread. I was looking to add some vero 29s to my CXA3070s.
Flower light.
Has two Z450Fs that may get moved to veg. And 6 Z230Fs
Main question I have is do I want to go with the 80 or 90 CRI?
BXRC-30E10K0-L-03
Or
BXRC-30G....
Was thinking E - 80 CRI but not sure.

What ever happened to Flux?
80 CRI seems to be what everyone else agrees on using. The CRI index will be considered obsolete (if not already) in the coming years, as a new system of light measurement will come into place.

Flux is probably growing with his lights instead of talking about them.
Why would cri go away? It's not a measurement for plant growth...it a measure of color rendition/seeability. And it's great at what it is for...
So what is the new thing you speak of?

I've noticed you only like to speak to me on certain grounds, specifically when you don't agree with something I've said.
Your answer to 'Where in the world is Flux' doesn't really answer the question, but merely adds a possibility. Nonetheless, your more than likely right about his whereabouts.
(Yeah) I figured calling it a light measurement rather than a color index would ruffle someone's feathers, I just didn't feel liked editing due to laziness (whoops). I believe there was an article or two that I came across through the forums here on RIU/LED that discussed how CRI will be replaced with some new tool of relativity, in respect to the color of aftermarket lighting. Hell I may have been the one that linked the URL(s).
Anyways, I'll try to find it so I can share the news and enlighten those who may feel unenlightened.

Ok, here a few links that help explain Color Quality Scale (CQS(That which I speak of)):

I have read about cri but not sure how applies for plank growth as a measure used to show how well something will look for human eyesight compared to looking at it under something like sun. But this isnt a meet counter in a grocery so...
I can only get 9 vero 29 3k. Assume I would run at 1400ma. So with the 6 cxa3070 z4 3k at 1400ma thinking i need a bit more so either dif spectrum or some 18s. They have 2700 vero 29s. A single 3500. Or mix in some other spectrums...
Or stick with 3k and get some vero 18s in 80, 90 or 97cri. Trying to fill out 29sqft flower area.
Or I order more 29s and get them when the come in stock...that may be best thing to do.
Thinking 15 total vero 29s with the 6 CXA3070s.

Let me put CRI this way...
CRI is the ability of a lamp/light to show all the colors in the rainbow/PARrange as well/as good as the sun/candles. The sun and candles are 100CRI.
In order for a color to be seen by the eye/CRI scale...it has to be emitted by the lamp. So if it is not emitted...it is not seen...and thus missing from the CRI.
When we look at 80 CRI versions vs 90+CRI...the difference is usually more light even representation in the endes of the spectrum(blue and red) than 80cri. Which would be good...except to do that they don't add more of the ends...they filter/block the middle portion...to lower the ratio so is more even, and each nm is more equal in output...but there is actually not "more" or "added" anything.
Which is why we say go 80cri...the total output trumps the minimal spectral gains.
The problem I see...and apparently CQS does too...is that CRI can be manipulated...2 totally different looking/feeling lights can have the same CRI...but are very different over all spectrally.
To me(and probably many others) CRI alone is worthless...
Only when combined with the spectral distribution chart, CCT, and comparing the same technology(led vs led, floro vs floro, or hps vs hps) does it become a possibly useful tool for a grower.
When it comes to a thread about INFO...then I like to make sure that said info is correct and well based. So if something is not matching up...or just wrong...then I speak up. But no where did I say you were wrong...just asked what you were talking about since at the time you gave no further explanation, elaboration, or links. So I asked...and like you noted, when you say "measurements" like you did, it has a different connotation. So I asked with a little explanation of how I was reading your post. Was that too much?
Spectroradiometers give ~15 CRIs...then average them all to the one you see published. The ones they keep are very similar to the QCS scale/colors...and probably are...i'll find out more. They are basically the CRI of each individual color...vs the spectrum as a whole that is published. Which seems to be what the QCS is from the quick read I did. I will read more when I get home.
You have a tendency to freak out when someone isn't on regularly. I gave a possibility...nothing more nothing less. Did I say that "flux said"?...no...just gave a possibility and a good one at that. What did you want to hear.

I don't troll you if that is what you're insinuating. If you had a grow thread I would comment on how you doing...look at other peoples GROW threads. I alway like to stop in and give props to GROWS. Even if it is a little tiny thing...if it is good for the situation/person I give props...not judge.

Now that I've had my cup of tea and have realized how your comment relates to GG's, I must explain the relevance behind my comment, specifically the one targeting CRI.
As far as I know, one can order COBs in a multitude of choices, with some varying in CCT or CRI. Each of these choices offers different colors for both the human eye and plant to absorb, while the latter is the focus in this subject.
While CCT is our primary target when considering the various COB choices in a given lineup, CRI has been of secondary importance. GG and Avnewb present reasonable points about color to human eye not mattering, as we are trying to illuminate the environment for our plants, whether they be tomatoes, peppers, or the cannabis plant, all the while supplementing their varying spectra needs.
However, there must be some significance to the CRI value of the different COBs on the market and while I don't have a direct answer to why it should be important for the consumer to choose one over another, I have witnessed popular and credible RIU members point out and demonstrate the advantages of using 80 CRI rather than 70 or 90 CRI.
So...
15 vero 29s? Each on some driver under 1400ma so like 50w each makes 750w plus like 350w from cxa3070 so about 1100w total making approx 35/sqft. Like to keep lower so dont burn but @16w/sqft as is I need to add some power before I switch to flower.
Would be something like this (x=vero29, @=cxa3070)
44" wide x 96" long
X X X
@X@
X X X
@X@
X X X
@X@
X X X
Edit
Well I bought 15. Approx 20% off so ~$23 each.
Now to chose driver and heatsink...

I couldn't have explained the relevance of CRI any better. Nicely done.
I'm not entirely familiar with the definition of trolling, as the extents of it are endless, so I will not say that I insinuated but more or less found a correlation with your comments (or lack of).
Your question to me about explaining my point was reasonable.
LOL I 'freaked out' when StarDustSailor went MIA.. well maybe not freaked out but decided to make a thread on it. Maybe a little too much BUT it made for an interesting thread nonetheless (Eraserhead emerging for the first time in my RIU existence and him raging on with some other stranger and the thread getting locked and freed).
OK so I went a little aggro on you today. Not everyone in the world gets along with everyone in the world. One of the relapsing outcomes of this imperfection is that over time we eventually tolerate one another and more forward.
Thanks for reply on that 1 I will be running them in series so shall not have to worry about the vf.
Also what is the recommended watt/sq. Ft with the vero/cxas?
I am upgrading to a cupboard to go stealthier for main grow which is around 35" tall 20" deep 30" wide. I currently have 20x 660nm crees 10x 730nm leds for flower initiators 1x ab bin 3000k and 2x z4s 3000k and was going to add 1x vero 29 3000k and 1x vero 29 4000k would it be overkill running these at 60w a piece or is it just a matter of controlling temps?

I shoot for around 30W per square foot with my Vero 18s, while running them at ~40% efficiency.
Heat may be of concern for you in a ~3' x ~2' x ~3' grow space with all that lighting you listed. Will you have airflow and exhaust for your space?
I have a 4" extractor fan with carbon filter 2x 140mm pc fans for Intake and 4x 120mm fans for air circulation.
