97,90, 80 and 70 CRI Sun Like chips .http://www.seoulsemicon.com/en/product/Chip-on-Board/
hello
you can make sentances you know^^
anyway i checked the spec of your sun like cob
and comparison of that
cree cxb3590 36v version (i wont take some too high voltage stuff...)
https://www.mouser.fr/ProductDetail/Cre ... MQJE7PUA==
i didnt find any 36v version of the sun like cob on your list that aproche the performance of the cxb3590, maybee im wrong, im really bad on electricy stuff, i still learn about it.
cheers

Aloha & our testing of the high CRI chips is ongoing and promising. Number data is one thing ,
plant response is another.
plant response is another.
cannot wait to see the result, their violet technologie is interessing the cri is awesome, should be amazing for photography but not enought power, i mean less than 100 lum/w .... wait and see result.
im more on putting white led @4000k 70cri and increase the cri on adding monocolor led like red :630 + 660 +730 / blue : 430+ 485 to cover the lack of the white led.
with that you increase your cri up to 90+ whith the monocolor led and keep the highest lm/w and penetration from white led
nichia did amazing job with theire 757 f1v3serie and the optisolis version with very high cri, kept some good lm/w too
im in love on their 5000k 97cri version which the spectrum is amazing!:
