I just know that left is LM561cThe picture on the right is supposed to be an lm561B?

http://www.samsung.com/global/business/business-images/led/file/product/lighting/201601/Data_Sheet_LM561B_Plus_Rev.5.0.pdfDo you have a efficiency chart for the LM561b by chance i heard they were a lot closer than 10% exp at lower watts
Personally I don't think those are even real photos. They look more like computer generated images and they use the same one for all diodes of the same dimensions.These are from Samsung's LED page ...
Yes theyre not photos, just Samsung's illustrations, i guess thats why they dont have that black dot either.Personally I don't think those are even real photos
That is my understanding yes. If you look at hlgs pics they don't show these tiny dots. I can see them from over 3 feet away on my strips and most others I've seen come from Alibaba. The photo I showed in my previous post is from an actual strip made from samsung showing the dot much more pronounced and in their spec sheet it is a lm561b+.So the B's have that darker dot showing in the diode whereas the C's are much less visible?
Not trying to be rude just playing devil's advocate. But if you look at the 1st pic 2nd diode down. It looks as though it has the black dot. Could they have mixed some of them together? Not asking 4 more pics or anything. I'd take your word on it and thanks for taking the time to share awesome!!!The Meijiu boards I purchase have been verified as legit lm561c s6 diodes. The following pictures are of 3 different led's being compared to the boards/leds from Meijiu. All 3000k same as boards. First picture is a lm561c s6, second is a lm561c s5, third is a lm561b+ s5.

Great pics! This samsung video also shows the differences between them pretty good - LM561B+ = same package as LM561C but smaller die:The Meijiu boards I purchase have been verified as legit lm561c s6 diodes.

This reminded me of this article. Albeit pointless for us but still it boggles the mind.btw these look interesting... 10% more efficient than LM561C?...
[edit - sweet, there's already a rollitup thread] - https://www.rollitup.org/t/samsung-lm301b.949988/
! .... but then where does the industry go from there!? what's next!? or is that it ... physics laws saying "you've had your fun, no more"
That's already the case with laser led's like osram. Also the cirus 1k is the same, i was disappointed they didn't get more info on that light.I think the future will be high-efficiency blurple.
But for now, we know where it is at.
Its inbound, not sure how long it'll take though (guess ~5 biz days), I talked them down in shipping price so that might've delegated me from Express to Standard though the parcel tracking # suggests its Express. Anyway from all reports so far they should be legit lm561C S6, and will do a flatbed scan when it arrives@PhenoMenal any news?
Interesting ... they say their light "produces more energy than it consumes" ... I'm probably not thinking about it right or missing something or still in the process of waking up, but... couldn't you make a PERPETUAL ENERGY device with such a thing!? which are supposed to be impossible as per the laws of physics!? *shrug* lolThis reminded me of this article. Albeit pointless for us but still it boggles the mind.

Its explained in the comment section that the "extra energy" comes from environmental heatInteresting ... they say their light "produces more energy than it consumes" ...
