I'm not sure I understand the question. o_O

It means that I presumed Samsung was already using S7 bin chips in some of their builds and was a direct response to the quoted text by Budies that posited soon to be released S7 chips. Is that what you mean?

Does anybody know yet the actual % difference from these and the old comparable CREE's? Im guessing the die increase means we will have to up/down-grade slightly with the past chips to match better for comparison.

As it stands it still looks more favourable to go with Citi's tbh...

CXM22 3000k or 3500k 90CRI best for flowering ?

I’m wondering the same thing. I’ve seen Some guys running the Citizen 3500 with good results but would love to hear from people running the CXM22 3500 and or 3000 90 CRI and how they’re doing.

its not up on cree PCT, and until we actually have bin codes on the new chips we cant really do anything with that anyway. and even then its just a guess on if it is "better"

with cree giving +/- 7% on flux per datasheet its anybodys guess.(though almost all mfrs run more like +/-2% off the production line in my experience)

-7% would basically push it into the next bin so take binning for what its worth

theres not that much difference between that and anybody else running the same colors from another mfr.

ive had great results with 3500k 90 (citis) - rig works well and im not ready to "upgrade" yet but would expect similar results with 3500k 90 whether i put citi, cree, luminus, vero etc in there

prospectively, but its not a sustainable business model at some point, its divergent sets it apart; what is the points on a commodity level that commands a higher price point.

I mean if we wanted like wise performance in a chip, we would all be using AMD CPU's we see what happens there. its not like AMD is a bad product, just as fast, maybe a little more watts but its still a very comparable product. you can save $100's I don't see many people going that way.

so with lighting, we want a lot of light coverage for -less $, whats the trade off? maybe we just haven't had the other chips long enough to start seeing issues, in color temp change or lumen loss.

there is a reason, I think they trade on NASDAQ, but your not gonna be there unless your product is worth it, vs a cheaper alternative.

As of today AMD selling more chips than Intel thanks to Ryzen. Most peoples buying their PC's from retailers that pushing Intel more than AMD powered systems. If you building your own rig - Intel/Nvidia combo is not that good of a value as AMD/Radeon.
