LEDgardener

what are your takes on these? they give a shit ton of lumen per dollar at high efficiency UPDATE: non-stock item. 1050pcs minimum order quantity

i stoped following cob market since cxb3590 , i was to focus on spectrum , middpower led and led pcb ^^;, im also wanted to know if those cob are nice comparate to others?
first its a 18mm diameter les cob, and the 3590 was28mm from my memorie, dont know if its comparable no?
what about the new cob lumiled gen 4 are going to be available on digikey and mouser, seem to be really good are they worth the price?

so wanna know about thos samsung cob and also luxeon, finaly i wannaknow which cob on the market have the best lm/w performance on 60w and 100w pliiiiiiiz

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...)

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.

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!:
