Tracking numbers update:
Phosphor22 - LX054010845TH
e1000 - LX054010831TH
Kame Sennin - RR146459793TH
Received the package of 100.
There will not be a proper review until next tuesday (I will have enough forum chat time but there will be no hands-on cave time possible).
Quick first impression of one random led from the package:
*plenty bright
*very pleasant tint to look at
*very smooth broad beam (60 degrees from specs seem correct)
*edge of the beam a bit warmer than the rest (found it not disturbing)
*at ~20mA, middle of hotspot: 3325K, duv –0.0039, CRI=97.4, R9=88.
Summary so far: great led 
Wow! Sofirn should get some of these.
Many will be waiting for the review djozz. Thanks.
Any 7x emitter honeycomb arrangement host or flashlight out there for these? Hexagonal/honeycomb is the most dense arrangement, I wonder why it doesn't seems to be widely used. 
How about this as a host? It’s 0.5w though, so I don’t know if my LEDs would survive that.

Received! Many thanks.
GREAT!

I’m really looking forward to seeing the results of your testing. 
Re-posting this old Yuji mod just for ideas:
My first LED swap which didn’t require solder. In fact I only used a screwdriver, wire cutters, and tweezers:
I recently ordered some batteries from Shockli’s aliexpress store and they threw in some freebies with my order. One was this cheapo keychain light. It has a 5mm straw hat LED that is press to activate and has a tiny switch to “lock” it on.
I bent and trimmed the legs of my Yuji 95 CRI 3200K LED
We have light!
I just now am realizing it had 2 stacked CR2016 batteries so I am probably giving this thing way too much voltage? Maybe a 2032 battery would have been more appropriate, who knows. I guess if it dies i’m out 55 cents…
If you still have stock I woukd be interested in 1 pack as well. See the PM.
The CR2016 cells are 1.5V nominal, so two of them would be 3V, which is fine for a white LED.
I dont know anything about the cells but when I look at replacement ones on Amazon it says 3V nominal
Huh. Yeah. I just looked. You’re right. Hmm. Curious thing.
I have used and gifted dozens of these small lights, all the white ones use 2xCR2016 and i have never seen a single one with a fried led.
These coin batteries have a high internal resistance so the voltage drops when you load them with a led.
CR2016 cells are “3V”, but their internal resistance is very high. Thus, 2x in series CR2016 cells drive a 5mm led well. 
That and the fact that you don’t turn that on for a sustained period. Even if you overdrive these LEDs and degrade them way faster than their rated lifespan, you probably won’t notice it.
CR2016 cells are indeed 3V. The “CR” code denotes a lithium manganese dioxide chemistry, nominally 3V.
Alkaline button cells are 1.5V and are given “LR” code. The typical form factor is also fatter and taller than lithium coin cells.
A pair of CR2016 cells shouldn’t be any concern, but because of the low forward voltage on the Yuji’s, they run pretty well on a single CR2032 cell, in my experience.
I haven’t done a controlled test, but I’d expect you would get more stable output and significantly longer runtime out of a single CR2032 compared to a pair of CR2016’s, although you might get higher initial output out of the latter. The massive voltage drop the pair of smaller batteries experience is in part due to a lot of energy being wasted on internal resistance.
Either cell does better at these kinds of loads with intermittent use (a few minutes at a time) than continuous use. It’s surprising how much the voltage recovers when a load was removed in a test HKJ did:

Thank you so much, rngwn!!! 
Mine arrived in Denmark today.
My wife have some tee-lights she bought in Ikea :
The tint in the original on the left is perhaps more candle like, but it also has a hint of green. I like the “upgraded one on the right better.
Thanks again for making these available.
LEDs arrived today, thanks!
