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.
I am Interested in 7-10 pieces of NCSL219B-V1 R9080.
But I am more interested in the ānormalā 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 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) ...
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 1x 7135 for example by a fair margin.
Thanks TA,
I confirmed the Nichias arrived in Florida, a couple more months and I will be back there.
Our appreciation for a job well done, mission accomplished.
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.
