Clemence has many Nichia options on his store too. Not XM-L2/XP-L die sizes, but the 319A is interesting.
Kaidomain also has some 90+ CRI 219B and 219C options.
xpl2 90cri leds (XPLBWT-00-0000-000UU640H) were available to purchase with the minimum buy as 1 led with free shipping on Arrow Electronics a little while back. I picked up one to test out, so you could always wait until Arrow has them available again.
Mouser has them in stock too, shipping isn’t free though.
Yes, I did. I put it in a Convoy s2+ and gifted it to a friend. I might have a beamshot somewhere but it was taken with my iPhone. I’ll try to dig it up later tonight.

good to know but I cant get his website to work. the illuminations guys does for me.
Cutter has some 95 CRI XP-G2s. Not very efficient, but the highest CRI I’ve seen in a high-power LED so far.

Did you find it?
So both are Convoy S2+ lights running off of an18350 cell, left one is running a xpl-hi v2 5000k led with a smo reflector and the right one is running the xpl2 90 cri 4000k led with a ledil boom reflector.
Thanks! Do you have a larger version?
So it’s definitely much warmer than the XP-L HI, as exptected. It seems that the middle of the spot is a bit cooler than the outer part?
I edited the picture so that it would be bigger.
Thanks!
The wall is white I assume?
Yes it is. It’s not noticeable with the bad picture but with the reflector that I used for the xpl2, there is a lot of spill without really a hotspot.
It is a year old thread, so I wonder if there is still a source of a high cri XP-L HI @3000K?
I need something this warm, capable of direct drive AND domeless, so it can sit almost flush with an asperic lens.
Why don’t you consider Samsung leds though you would have to slice the dome to make it domeless. You can look here:

Thanks for the suggestion, these are completely new to me. Looks like the max current is 3amp, right? At this level I am completely happy with nichia e21a from Clemence. Hope to get 7+ amps out of xpl hi.
Additionally, several components vendors sell LH351Ds in various color temperatures in single quantities. See Octopart search .
The LH351D can easily take 7A and peaks around 9.
Check out this test done by TA:
kiriba-ru sent me these LED’s to test. I had never even heard of them before so I didn’t hold out a lot of hope for them but they really surprised me! They have one of the lowest apparent thermal resistance I have seen so far. This can be seen in how the output hardly jumps from a cold start, that says it is moving the heat away very efficiently. The output is also very impressive at over 2200 lumens! This is more then any other 3V LED I have hot tested. The XP-L2 will make a bit more from a co…
I also built a convoy c8+ using a 4000k 351d, here:
I was inspired by djozz and built this C8+ out with sliced Samsung LH351D 4000K 90+CRI. I must say I do like the tint on the led. I’m using a qlite driver w/ added chips at 6a. ![image] ! ![image] ! ![image] !
This led is definitely worth taking a look, if you are looking for a high output high cri led. There’s also the lumiled luxeon MZ but I don’t think the warm tint is readily available and you have to deal with cross in the middle but it might not be an issue in an aspheric. Here’s a test of the led:
LED test / review EN Lumileds Luxeon MZ (3 V variant) LMZ9-QW57 UPDATE --- 06/22/18 --- diagram Vf / light flux depending on Tj added! UPDATE --- 06/23/18 --- raw data added! (link) [image] Some time ago I found a LED which have sparked my interest. The most LEDs with high color rendition (known as ‚high CRI‘) are not very powerful, have not the best efficiency and also can’t handle high currents like other LED series. The Luxeon MZ is very interesting becaus…
led4power.com is going to stock the luxeon MZ soon, so you can look for it there or if you want them now you can buy from digikey.com. Digikey also stocks the Samsung leds too.
