This is 2300k though. “2800k” is just the WB setting.
Oh my bad, I read 2800K trough the glare on the photo. 2300K is even better, then!
10 of those in series to an AMC7135, done for each tint, controlled by three Arduino PWM pins. A good idea?
I.e., a panel of 30 LEDs with some degree of tint control. That’s my plan. Housing done with my 3D-printer. My desktop is to be illuminated.
Gotta be careful with the current though. This batch of 2300k LEDs has 0.1v less forward voltage than the other two tints and also (supposedly?) 45 deg angle rather than 60 degs.
Will do a quick voltage/output test when my batch arrives, and post about it here.
Hope the tint is below the bbl or it will look too yellow at that tint. If so, I’m in.
In for 1 pack of turbo warm 5mm
In for a pack of the 2300k
Order paid last night has been shipped 
News: 4000k variant is in the pipeline. This is from a different source than what’s already put on sale. The tint is unknown (and possibly imprecise) and these costs me more than the previous source. I will do some basic tint testing once they arrive. As always, I will give away someone a sample for CRI test.
Do you have many of that 2300k LEDs? I have one light with 5mm LED on the way. I’d rather not order before I have the light in my hands and see if it’s mod-worthy….But if you have the last pieces I might just bite the bullet.
Still have about half the stock (~500pcs) left for 2300k.
Ok, I’ll wait a bit then
I’m in for 2 pack 2300k if still available.
Mine arrived in Denmark today, thanks for making these available 
Wife didn’t like the 3400K much, but these 2300K she finds much more “candle like”
Happy wife happy life 
…and also an arrival in Amsterdam.
I did some measurements: 5.8 lumen at 25mA, peak of 22 lumen at about 150mA (but the curve is very flat there, if I had made one )
The beam is very smooth, the spot has a soft border with no tint changes.
The led is a bit shorter than the typical 5mm led.
I measured tint at 30mA:
Tint (I checked 2 leds and several currents) is around 2400K and not 2300K. It is right on the BBL and CRI is great. Rf=92.7 , Rg=99.8.
So another really nice led from rngwn, love it!
rngwn, does your manufacturer make SMD LEDs also? I think they might have some uses.
Do you have a “before” pic of those to compare?
They do make SMD’s although I will need to do more research whether it make economical sense compared to the existing ones
There are very few options for CRI95+ SMD MP LEDs with reasonably priced worldwide shipping.
Actually I have found literally just one offering on Aliexpres, for 2835 LEDs. Everything else seems to have expensive shipping. 
I suspect I’m missing something and I spend merely an hour or so on the search. But anyway - this is not something widely and easily available for a reasonable price.
