Sounds promising! I am curious of your results!

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!

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.

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.

I’d be in for some small-die 219b 9080’s, at least enough for a triple.

Thanks, but I’ll give it a go…I want to be able to say I’ve done it Silly

I’ve just remembered I have a single board too, so that can be a practice piece!

Hi Guys,

 

I have a bad news. And I want to also clarify things about NVSL219B-V1 Ra9080 I told you earlier:

I called the Nichia rep this morning for our additional purchase of NCSL219B-V1 Ra9080. He then reminded me of our earlier discussions approx. a month ago.

It was the NCSx219B-V1 Ra9080 which is about to disappear from the market NOT the NVSx219B-V1 Ra9080

 

Sorry for this confusion 

 

Good morning and have a productive day ahead (or a productive dream to those asleep already) ...

 

- Clemence

Pity about the small die 219B, but it saves me a mod plan (have already more than I can do) Smile

Ok, I got the triple 219B fixed today, there was a solder blob shorting to the pill, fixed that and replaced the now melted spring and it is good to go.

I love it, it does take 3 of them to equal a single XP-L2 in output but the tint is amazing!

Does about 800 lumens @ 2.5A regulated vs 880 lumens on my triple 90cri 219C 4000k version with the same setup. So about 10% less output at that power level. I used long 24awg wires to limit current and current tops out around 6A with a GA and around 7.5A with a 30Q, it puts out 1600 and 1750 lumens respectively and the heat is manageable.

I am using the 1507 optic right now with the 219B, the 15011 would be floodier but also should give a bit nicer tint still due to the tint mixing. Perfect for a photo light.

I so want to build a light with ~20 of these as a photo light.

Also, keep in mind that the higher the drive current for the LED the better the CRI. Part of why my 7x SRK looks so amazing is that it uses a basic FET driver so you get the same CRI as full power even in dimmed mode. The CRI appears to noticeably improve as current increases, Turbo looks better then 1× 7135 for example by a fair margin.

Thanks Texas Ace for the quick delivery of my Nichia leds & all the good information on BLF.
I ordered 2 Jaxman E2L hosts to try making triples. I have just (2) 219Bs so considering a mix of 219Bs with a 219C in the Jaxman. New to modding & soaking up any info you or others post.

As Clemence posted above, unfortunately, the NCSL219B-V1 9080 is already cancelled because Nichia has no stock of them.
There will be a new group buy of 3xNVSL219B-V1 9080 but I have not heard of sw40 before.

Ai, I hoped that there would be no reason to join your third round of Nichia's Clemence, and you just smashed that hope. I'm in for the sw40 Sad

 

 

Sw35?

Hmm, I feel bad I smashed it…
I also got some 3500K (sm355) Ra8000 319A for you here. Delivered much too late earlier. The 3 steps 319A is surprisingly 30% more expensive even it’s only Ra8000

My stash of leds will get to a next level once again.

I may not even bother building them in lights anymore, just keep them hidden in a small box and just look at them every now and then. Nobody will know! Flat Stare

I use most of my surplus LEDs to lights up the garden, the streets close to my house, even the sewer in my front yard. Still waiting for Sedstar’s package for the 4500K XPGs.

Have you tested any of the LEDs?
