[GB ended,discussion only] CRI > 80+ NICHIA 2000K-6500K [E21A/219B/219C/319A/144A/757GT-F1(Optisolis)]

So guys, is anyone interested in NCSL219B-V1 R9080 ?

I know Clemence will be ordering new LEDs very soon. Of course he will order another batch of NVSL219B-V1 R9080.

Question is, are enough people interested in the small-die version to justify the risk of ordering at least 100 pieces?

The small-die version should give a very nice tint and CRI just like NVSL219B-V1 R9080, but output would be even less.

The advantage is in the cd/lm numbers. It’s like having XP-E2 instead of XP-G2, maybe a bit better. The NCSL have the same XP-footprint as the NVSL and have the same max current rating (1,5A constant). So, I think these will be very nice under 20mm Carclo triple optics, not as bright as the “normal” 219B, but with a tighter beam for more throw…

I would definitely be in for some. I just don’t want to talk Clemence into ordering 100 pieces, if nobody else is interested in them. That would be too much of a risk.

I definitely prefer the larger die for this kind of emitter. Now, if they made a flat-dome 219C (no, not the E21A), I’d buy that. Solvents are smelly.

I would expect the NCSL219B-V1 R9080 B11 to achieve about 87% of the light output of the NVSL219B-V1 R9080 D220 or 80% of the NVSL219C R9050 D240 at 1,5A. That wouldn’t be bad at all for that small-die emitter.

I’ll take 12. Maybe more if I find another application.

88pcs to go….

10 for me

Some advice needed, please. I want to mod a Surefire E1B with either one of the 219C sm503 or 219B sm453. Would you prefer the 219C with H17F and the possibility to direct drive it with 8A AW batteries? Or stay reasonable with the 219B with a linear 1.4A driver? Max output vs. max color rendition?

I am not yet sure what to do. Thanks for your input!

Both are great options. For a single LED setup I prefer the 219C simply due to the extra output it offers. But then I like having at least 700-800 lumens on tap in regulated modes of 2.5-3A.

For a triple setup I will know more later, building a triple 219B 9080 to see what it does later today most likely.

Sounds promising! I am curious of your results!

Very expensive FL… :open_mouth:

SUREFIRE EB1

It is only an old used E1B, so it was quite affordable :slight_smile:

Well, had it all together and bench tested it as working but when used with a battery it shorted out and something is shorted to ground now. Not sure what but gonna have to take it apart to figure it out. Not sure when I will get time to do that.

It looked good during bench testing though, I think the LED’s are ok, just the driver if anything. I was using a driver out of my parts bin so not sure what the issue is.

Hello Clemence,

I'm interested in the NCSL219B-V1 9080. Dropped you a PM.

Thanks!

I’m in for 4 NCSL219B-V1 R9080 leds, I think. Also depending on colour temperature, and a bit on price.

These are perfect for the narrow carclo optics, I know that the XP-E2 gives a tight and beautiful spot (better than the XP-G2), and so will these!

Clemence, I love it that you make all these unobtainable special Nichia’s available!

Not just me Jos. The big N is getting interested in our little world….
Looks like You, Tex, and Maukka contributes in the rubs

Djozz, that’s exactly what I had in mind. Should be very nice with Carclo 10511 for example.

@Everyone, FYI, djozz tested the predecessor of the NCSL219B-V1 in a low CRI version, the NCSL219B. Compared to the XP-E2 R3 that’s a pretty impressive performance, if you ask me.

I would love for Nichia to really take a liking to our world, there are a few holes in the LED world that are waiting to be filled.

I would love to see a quad 219C die LED on a 5050 XM-L footprint with every possible effort put into heat sinking, no worries about how big or tall the LED is. Make it a domeless LED with only a thin coating of silicone to protect the die as well. Then put all the dies as close together as possible and wire them in parallel thus allowing us to run it off a single cell.

Done properly it should be capable of 2000+ lumens on a normal star and over 4000 lumens on a DTP copper star. It would cost more then normal but it would be WELLL worth the cost for flashlight guys.

A simpler emitter that would be great to see would simply be a domeless 219C optimized for throw.

Also putting the phosphor from the 219b 9080 onto a 219C die, The 219C handles the heat WAY better then the 219B so it would allow for more output when driven hard I assume.

Just got my 3 LEDs, thanks to all mebers that made this possible !
Thank you Chouster for a great packaging and all the work that it required :slight_smile:

Sure. I’m interested in a small die 9080. Maybe 5-6.

I am Interested in 7-10 pieces of NCSL219B-V1 R9080.

But I am more interested in the “normal” NVSL219B-V1 R9080 or Better a 219C R9080.
If the NVSL would be aviable too, I would only take 3-5 of NCSL219B-V1 R9080.
