Except, that photo is not dedomed. That’s sliced, like a HI version. I completely dedomed the XP-G3—bare. The S5 3A dedomed looks just like a dedomed Nichia 219C in tint, also. Probably the two closest tint LEDs I’ve seen, dedomed.
Luminarium. I found something extremely perplexing about this entire ordeal over on my end. Now, maybe I am wrong. Maybe I compared 2 other emitters, that are not the same as your “big” and “small”. But I did compare two “new” and “old” Cree XP-G2s to find this interesting thing. What I found, is that my new Cree XP-G2 indeed had a die that looked larger than my old XP-G2. That is, until I measured them to find that they were the same size. What was actually different about them was NOT the die size, it was the anode/cathode insulator line—a package change—that had the insulator line closer to the die perimeter, leading one to believe at first glance that the die was much larger. But it wasn’t!
Has anyone confirmed this, 100%?
I too noticed the color difference just like was stated; new had more of a dull yellow phosphor color, old had more of a bright fluorescent-yellow phosphor; dedomed. But my two indeed only varied in that line around the die, not the die sizes. Another person has also said he noticed no intensity difference between them. I am starting to wonder if some of this is actually human error/perception-based, and not a die which is larger. I bet that any person would say the “new” die is larger 10 times out of 10 when I put them side-by-side on the table because of this package line change, but in reality with my two, no.
I really don’t think anyone should ever think to go after the person that sold them these LEDs. The LEDs are only “bad” in your mind, as you are the outcast user of them. I read some of that earlier about pulling money back from the supplier and I couldn’t believe someone would want to go after a supplier of something that Cree handed to them under the same specs they had always been dealing with. You can’t expect a supplier to be pulling out his caliper to gauge each LED die size, after dedoming one! That’s just not how this stuff works; only inside of our extremely small hobby-bubble on a corner of the internet does it work in die-sizes and high-kcd throw. The industry works in those very specs you see from Cree, but no where does Cree guarantee a die size, or certainly a lux value that cannot be reached.
I have 9 XP-G2 S4 2B laying around for a project. I ordered them a year ago from intl outdoor.
Can someone please confirm they are the good old production typ ones.

He won’t make a group buy , it’s obvious because he only send with expensive shipping overseas .
All the 2B stock is from August 15 (asked welight this morning) the same as those Mitko received .
If someone from AU wants to do it it’s something i don’t know .
Ok,
I can understan everything but I simply can’t understand why he does not want to reply in this thread with macro shots of that reel so we would know for sure and risk those expensive shipping. If I am paying expensive shipping than I got to be sure I have real thing
It seems that Cutter has them but he does not want to reply and confirm with macro shot that they are good old ones.
I would order from him… And it is really not problem to spot differences between “new” terrible(el terrible :confounded: ) emitter and good old one :+1:
Take macro shot of that reel… No need for group buy but owner of that store should confirm that they are old ones. No one wants to invest 500-1000 or more $ to get Mr. “New” :confounded:
I paid even more than that but I really need them so I can’t negotiate price
I recomment you Newark, the past year i bought some high CRI cob emitters for my home interior from them, the order was for arround 120$, the shipping 42 via DHL and they tried to charge me 185$ for the ” packing, handling and freight”…
Who knows, maybe they started packaging in stainless steel gold plated boxes or something
