90cri LH351D 4000K (SPHWHTL3DA0GF4T0Q6. cri=93 r9=75 according measurements)
As I already said 1.6$/pcs. 5$ registred post. 
I found source of cheap 90cri LH351D 4000K
SPHWHTL3DA0GF4T0Q6.
It is new 3535 Samsung led with Max current 3A. It can work with carclo triple optics.
So I can provide opportunity to buy for 1.6$
Could it be interesting for someone?
Guys from superfonarik.ru helps with measurements.
LH351D 4000K
LH351B 3000K 90cri
XP-G3 5700K 90cri
The last 2 LED also very cheap ~0.5$ and 1$ respectively.
According to this sheet, the Q6 flux rank emitters only do 764 lumens at 3A. That’s only 40 lumens less than the equivalent 219C according to this test. How’s the tint?
Reviewer for ThorFire, Olight, Sofirn, and Folomov.
I bought a couple of pieces.
Exact bin was F2T7Q2. I found it less greenish than 219c 4000, but I plan to measure it in sphere to be more strict.
Subscribed.
Let us know if you decide to grab a nice bunch of them, pricing and shipping costs.
Cheers
Looking for interest on copper pills for SK98 flashlights gals and guys…
Yes, I’d be interested but a bit anxious of the tint and beam profile it produces. The 90CRI 4000K LG led that Jaxman used recently was very green and caused an ugly tint shift in the various optics (link to maukka’s test), and I always thought that Samsung and LG were very similar. But if you say the tint is as good or better than the 90CRI 219C, and if you could find out that the tint shift when used in a flashlight is not bad I’m convinced I would like some for that price

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.” (Gus Speth)
Now I try to decide with quantity.)
Pricing and shipping will be 1.6$/pcs and 5$ (with tracking number)
At least the CRI70 5000K Samsung LH351D was good with a suitable reflector. But it wouldn’t be the first time when a higher CRI and lower CCT emitter would be worse…
I’m interested.
F2T7Q2 bin. T7 refers to the chromaticity coordinates, about over if slightly below the blackbody locus, and a tad less than 4000K. Shouldn't look greenish at all.

That T7 color bin looks like it sits very close to cree’s 5A2, which has been my favorite tint so far, I’ll definitely have to try some of these.
maukka, are you going to test these?

Received my 3x LH351D today. Installed them inside a Wuben TO46R. They’re really nice. No tint shift to speak of in the clear triple optics. A simple filter will perfect the tint on most modes if you need to be on the BBL. On higher currents it’s already superb.
And what’s amazing. It offers Nichia like beam quality but reaches output comparable to the XP-G3. I measured equal lumens before and after the swap. Although one of the original XP-G3s was dedomed so didn’t probably live to its true potential.
Very nice, I should be getting some soon, I’m planning to put them behind frosted optics in an E2L host
I received my 6LH251’s yesterday.No time to do anything at the moment.Thanks AEDe.
Looks good Mauka.
Is it the same output with regulated driver or with FET?
Thanks Maukka!! I appreciate it.
They are XP-L sized. I think they should be compared to the XP-L2 90CRI 4000K 2-Step, which is very efficient, but has a terrible tint (Duv 0.6 in the low/mid modes with reflector – SC64c). So this LED is indeed much better, similar to the Nichia 219C 4000K R9050 (which has a somewhat yellow tint though). At high currents it is probably noticeably brighter than the 219C R9050.
EDIT: I just checked the datasheet. At 3A the Vf is only 3.28V and the thermal resistance is 2.2°C/W. So it’s actually quite compareable to other XP-L sized LEDs. 765-810lm @3A & 85°C. 77-82lm/W, so definitely worse than the XP-L2 in that regard, but only because of the used Bin.
EDIT2: I just compared these measurements to those of the Nichia 219C 4000K R9050 403. The Samsung LED has a higher TM-30-15 Rf & Rg, a higher R9-value and a more balanced spectrum. The Duv ist very similar (unfortunately…).

Played with Lee Zircon minus green filters. The results are promising and visually the light is gorgeous. It really makes every color pop, even over saturate (Rg 102). I think I’ll stick with the 804.
With 803 minus green and 17% output loss:
804 minus green and 15% loss:
805 minus green and 11% loss:
Thanks, maukka for the tests.
Now I have left only 23pcs of 351D and 4 people send me PM
I’ll send these 23pcs. Then I’ll order more 351 in a week(+3 days to get it).
So please express your interest in this thread, I’ll make a list.
Small discout for orders >20pcs – 1.5$/pcs
Thanks for the measurements! I have a sheet of 804 at home, as soon as these arrive I’ll make good use of it. By the way, does anybody know where to get some good optical glue?
I’m interested in a few myself.
Deleted, sory if it’s important. But you should delete it yourself too)
Thanks!
Also thank you for offering these in low quantities for such low prices!

Actually I simply found strange good shop in nearby with extremely low price where “wholesale” means >35$ ))
https://translate.google.com/translate?sl=ru&tl=en&js=y&prev=_t&hl=ru&ie...
(55р=1$)
So if someone will be interested in something else (not 351D) it is posible to order too.
Well, still, you’re doing the work ;).
Thats interesting. Is there a version of this LED with a smaller (1mm^2) die, like the Cree XP-E and Nichia NCSL219B?
Project Excalibur - Next Generation LED Thrower (UPDATE 2018-01-15: 1.7Mcd)
Portable Thrower Comparison
Yes 351B max current is 1.5A. https://e-neon.ru/moschnyie-svetodiodyi/moschnyie-svetodiodyi-1/sphwh2l3...
There is also 351C max current 2A. But I dont know chip dimensions.
I’m not sure. The die seems a bit bigger compared to that of the XP-E2, but everything else (max current etc.) is the same. Unfortunately they only have the 90CRI version with ~3000K.

You are right
!
xpg and 351B (90cri 3000K)
The shop I used has >400 in stock . I ‘ll make order next week , and I hope I will reseived it at 16.04
I just picked mine up at the post office. If time allows I will check one in a flashlight. I’m very curious about the beam profile!
Thanks again for making them available AEDe!
