I think he needs 2000-3000 emitters.
Yep, that^.
Depending on the batch size of the lights we would need several thousand LED’s for production.
Wow that’s alot of warm emitters. Have you considered the SST-20 3000k 95CRI, which was tested by Djozz. ? It looks promising.
I also stumbled upon a Samsung LH351D 2700k 90CRI but I think unless you can select the tint bin, it’s probably going to be too yellowish/greenish like all of the other Samsung emitters that seem to sacrifice good tint for high efficiency.
lol, I need 2000-3000 pieces of 4500k to 5000k 90cri emitters.
Warm emitters are still a long way from being accepted by the general public, so trying to stick to the much more popular 4500-5k range.
OIC. I thought it was 2000k to 3000k for a NASA application. hahaha
I wonder how Fireflies got so many 219b 4500k 9080 for their ROT66.
I wondered that same thing and it seems they got the last of the 9080 219B’s that Nichia had laying around as they were not available when we got in contact with them.
Yeah, just looking for a whole lot of good tint LED’s. While I have a few novelty lights with warm LED’s I don’t find myself wanting to use them except in times where I am worried about my night vision for example.
Maybe because the general public doesn't even knows jackshit? Exactly this last knight I was speaking to a close friend, one which still seemed “brainwashed” by the general cool crap white ignorance in these matters. Showed him my latest CRI90+ 4000K XHP50A powered :-D SK9V8… He ended up suggesting me to tweak one of his regular SK98s with a high CRI 3000K emitter. He had already seen this lovely T3 7A4 CRI90+ XM-L2), thank God.
Cheers :-)
Yeah, as time goes forward the preference seems to be getting warmer and warmer.
Although long term I see the favirote staying around the 4500-5000k mark as a lot of people love it and most others don’t hate it. So it pleases almost everyone.
A high CRI 4500-5000k emitter is really great to look at as well, particularly with a hint of rose in the beam.
What is so good about this 3000k XM-L2? How is the tint? Any color testing by Maukka or the like?
No tests done that I know of. Lovely looking warm output. :-)
Cheers ^:)
Sweet! I would like to try it for my bedside light.
Yes, it is pretty. A few weeks ago I beam optimized a friend's SingFire-L05 headlamp which I once modified with such T3 7A4 emitter, to change its optics from reflector to TIR. Did it with this 35.8mm marble grain lens @ Yajiamei Optics plus two ∅35×2mm flat lenses on top to supplement the total lens setup height. Worked like a charm, and when I turned the headlamp on again I was struck with the reddiness of the thing versus an S2+ class torch modified with a first batch (T6 chromaticity coordinate) 4000K CRI90+ LH351D plus wide beam TIR, which looked green in :-D comparison LoL! Lovely smooth and wide beam for close up work.
That was another day in a modder's life. ;-)

Has anyone used their 351B 3000K 90cri leds on a light yet? I haven’t found a light to use these leds on yet but I wanted to see if anyone could report back and let us know how they look.
I got 2 triples earmarked for lantern use, one with the ww 219As from FT, another with a 3-up of the 351Bs.
Not much time to play with anything yet, as Something™ always comes up…
I was just about to order and realize that it is a 7A3 and not 7A4 in your link. I would love to try the 7A4 as that is more rosy. Do you have any idea where the 7A4 can still be purchased? Thanks.
I put one in my Nitecore Tip and really like it. Nice warm tint and beautiful colors!
I believe that “7A3” is actually a typo:
I see “7A4” in the label.
Cheers :-)
Oh you are right! Sweet!
Any chance of another group buy for the 4000K LH351Ds?
My LED has arrived few days ago. Thanks for the group buy
