There is really no reason to argue. The 219B is a good looking LED but not something we should be using much going forward when we have better LED’s available.

But sadly, there’s no replacement for the 219B 9080 or 9050 in terms of light quality. The LH351D is no comparison. Hoping there will be 9080 219C with less green in the future.

The high CRI Luminus SST-20 series is very promising, the performance is in between 219B and 219C and at least the 3000K version (the only type currently available) has close to perfect tint and CRI. The only downside is that the tint does not go over 4000K.

The 9080 219B has been discontinued so that is no longer an option sadly (I have been trying to track down an option to get some for a light that is in the works and they are not to be found) , thus the best option that I can think of is now the 219C “E bin” 9050. Which is what I am looking into now.

It should be the 219B tint with the 219C performance. Just in the 9050 flavor instead of 9080 (although when tested I think it got quite a bit over spec in this particular bin)

I saw that test and it does look interesting but the limit to 4000k and warmer is a real bummer. 4500k is about the warmest the general public seems to like.

I would consider a 4000k version though. 3000k is too warm for me.

Yea I saw your review and got excited and bought a triple SST-20 and a P60 pill from Kaidomain. The triple mcpcb fits carclo optics so I might swap it in my Wuben TO40R to test it out. We need some 4000k and 4500k 90cri with good tint though for mass adoption in production lights.

The LH351D in this GB is T7 tint bin and the previous was a T6 tint bin. I’m thinking if there’s another GB, maybe we can try the T3 bin. That should eliminate any green or yellow.

How many of the 9080 219B do you need? What tint? I have a bunch on order from Clemence’s GB but haven’t received them yet. I might be able to send a few to you.

Where can I get the 219C “E bin”?

Oh, somewhere between 2000 – 3000 Wink lol

It is for a project light that is in the works.

Thanks for the offer though, I don’t use the 9080 in my personal lights much for the simple reason that every other LED I own looks horrible after using the 9080’s lol.

Clemence had some E bin LED’s but they sold out, they appear to be what we have been wanting with 219B and 219C output except they lack the 9080 CRI. Although the only LED’s nichina offers with that CRI seem to be the E21A’s and similar LED’s that are hard to use in flashlights for various reasons. The 219C is much simpler to use which is why I am trying to use them.

2000 to 3000 219B 9080 would be extremely difficult to obtain. Maybe just try the SST-20 95CRI?

Impossible is more like it, it seems they are out of production.

The SST-20 is a consideration but looks like they are only available in 3000k. Looking for something in the 4500-5000k range.

Right now the most likely candidate is the 219C E bin 9050. Should be like the 219B but with slightly lower cri. The best option available at the moment that I can find though all things considered. The E21A has so many design challenges it is the last resort.

But I thought you wanted to try 2000 to 3000k in your project.

I would prefer a 219C E bin 9050 than a 219B 9080 because that 5 CRI would be impossible to tell. The tint matters more and the 219C has so much better efficiency.

I have Clemence modded me a few Tiara headlamps with the 4xE21A. Seems like it is only good for head lamp applications with a frosted or diffused lens.

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 Big Smile 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.

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?

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 Big Smile comparison LoL! Lovely smooth and wide beam for close up work.

That was another day in a modder's life. Wink

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 believe that “7A3” is actually a typo:

 

I see “7A4” in the label.
