Calvin, do you plan to stock ‘plain’ (R70, R8000) 219Bs?
These are pretty interesting too, maybe not exactly comparable to HiCRI versions, but they are somewhat ‘better’ than, say, XP-G2.
I`ve been searching and comparing, but my so to called News.. might not be what we are looking for...
it doesnt show NW with 92typ CRI, which is Minimum 85CRI, but only Warm White....
do you guys think the same?
I thought I found the successor of the NVSL219AT-H1, but it seems like Im wrong....
OP edited.
These LEDs will eventualy be available in neutral white, maybe in a 6 months or a year.
I was afraid Nichia had abandoned the HiCRI direction when the first 219B came out, but I’m happy to see now that I was wrong.
on the charts at 34:35 listed as White. Don’t believe me? Let me shine mine into your eyes! 
But seriously, that’s what I was looking for as the White version in A is what I have in my little custom Ti light. They are indeed showing the White 219B at 5000K maintaining 92CRI.
This article sums it nicely, and gives a link to the datasheet 219B
Edit: Or perhaps they’re only claiming a CRI of 80 now as the highest. Interesting.
Edit II: Full specs and complete data sheets are now available N219B Secifications If this page doesn’t want to link directly, go to the Home page and watch the scrolling header for High Power Series (I think the 3rd one) It’s the 119B/219B set and will give a list of all the variants. A click on the variant of choice will take you to the full specs, and at the bottom of that page a PDF can be opened with all the details we’re used to seeing. My copied and pasted link wants to drop the last quote mark off and thus not direct link. it should read http://www.nichia.com.jp/en/product/led_search.html?op=cond=whatsnew=‘x19B’ , hope this works!
The last ’ mark is getting pushed out in my link above, the software here is doing it. When Nichia tells you that page isn’t available, look in the address bar…add the ’ mark to the end after ’x19B and hit enter to go straight in to the page. Sorry, it’s Monday! :~
Does anyone knows what CRI this particular Nichia 219A might have ???
It’s 5000K… it does say it’s up to 92 CRI for warm white but this is 5000K… I can’t find CRI value in their datasheet (or I’m just blind)… the efficiency of it is right there around XPG2 high efficiency bins (R4 and R5)…
Until now I was using IS’s 4500K 92 CRI and now they are out… I believe I would be VERY happy with this one if it’s over 80 CRI…
That’s exactly where I got the one in my custom made Ti Neck Light.
In their Sept or October 2012 catalogue, it lists the high efficacy 219A in white as between 80 and 83 CRI. Page 21
Yes, an additional 0.3mm in diameter. So will it make a difference, I wonder? Are domes meant to fit tightly into the reflector or is there always a nominal gap?
So many manufacturers are using a centering ring these days, the reflector starts fairly far away from the actual emitter dome. I have lights where the reflector touches the dome, and I have some that it’s not close at all. Does it affect the beam profile? Not sure. Seems like the throwers like the reflector away from the emitter, I don’t see that the flooders care much either way.
The only real world difference I can see is that if an emitter is not perfectly centered, the contact with a reflector can push the dome off when removing the head…or at the very least scar it up.
I recently tried an experiment with a big light. The Defiant 3C Super Thrower has a massive reflector and it’s quite wide as well. The beam profile is quite good, with the target being for throw. They use a large centering ring around an XM class Cree emitter. I’ve got a Solarforce M8 that uses a hybrid reflector. The area adjacent to the emitter is orange peel for about 12mm, then the rest is smooth. So, not being one to leave things alone, I glued an 18mm McGizmo orange peel reflector into the centering ring around the XM-L2 T6 (I swapped from XM-L U2) to see if it would tighten the beams hot-spot. It did! And also smoothed the spill area beautifully! With a caveat (as happens so often) The hot-spot converges at about 30M then starts to spread back out a bit. So in the end, I’m not sure if it’s actually helping or hurting the throw. Before gluing it in, I tried the light without the large reflector, only the small one, and it was all flood. So this combination merges the 2 aspects.
97 yds to the red oil drum, shot at 28mm to show beam profile.
I had read that the area closest to the emitter dictates it’s spill while the outer wider portion is responsible for the hot-spot. Overall design or shape determines how well these 2 blend into each other. So the wider dome might be in an attempt to fit into the reflectors and TIR’s that are commonly available, to facilitate the beam’s transmission patterns and visible output in order to better compete with Cree and SSC. Efficacy, the name of the game. Seems to me Nichia is trying to get into the game in a bigger way, pointing at home lighting and street lighting with more efficient, visually better outputs.
A quick check of the older catalogue vs the new one shows both 219A and 219B emitting at 120º transmission angle, so I’m not sure what’s been gained by the slightly larger dome.
The datasheet has not been updated to include the R85 version (85min 92typ CRI). NVSL219B specs overview and datasheet
Nichia is just showing some of their other new offerings.
Some links are not parsed properly using Simple Post Editor, Advanced will get it right. You can also still use Simple Post Editor but insert the link code manually < a href=“Product Search LED | NICHIA CORPORATION>
(remove space after <).
Thanks, Dale. That’s really interesting! It would be nice if there were more lights with their LEDs.
Without the little reflector added, I am guessing you cannot light the red drum very well (no hotspot)?
Those are “Typ.” chromaticity coordinates. Typ coordinates are also listed for R70 and R8000 but those are available in different color ranks. R8000 even has the same “Typ.” chromaticity coordinates (0.434; 0.403) and it comes in sw45 (4500k).
From the NVSL219B datasheet.
Until nichia updates the NVSL219B datasheet we won’t have proof.
The color rank chart from Catalogue 2013_01 suggests R85 will be available in sw45.
I’m sure CalvinIS is requesting the one we want. :bigsmile: He did bring us the original nichia 219. 
R85 is not listed on NCSW219B either. Unless nichia is punking us, serving you that page with different specs and datasheet. :~
Simply isn’t listed in that one column, other 2 columns show 70 and 80, sorry bout that.
I hope IS will get EXACTLY the same color range and CRI number for new batch of Nichia’s they are working on but this time something above B10 bin, whichever they use for these new LEDs they are about to offer… so good ol’ buddy but more efficient… I’d be happy even with 5% increased efficiency…
(anything less than 49-50% is hard to notice anyway)…
Until then I might try that 5000K range with 80 CRI… seems about the same efficiency with CREE XPG2 R4 or R5 but slightly better CRI value…
I’m sure we will be pleased with what they bring us.
B10 is the highest bin for NVSL219A-H1 and thats what IS got. I’d bet they will get the highest bin NVSL219B in the tint & CRI we want. No worries. :bigsmile:
All we have to do is keep some money aside & wait.
This is the 5000K 219A that’s in my Ti light, pulling 800mA. Same camera settings as when I shoot the big boys, same 97yds to the red oil drum. Not really fair to ask a tiny light like this to throw a beam 100 yds, but hey, such is life! It make’s a surprising amount of light, especially in close confines and a dark space, like the attic when the big light conks out. 
But the profile of the beam is much different. It does have a hot spot, larger, and less general spill around the hot spot. To be able to cover the width of area it now covers, and still have an obviously brighter hot spot is pretty cool, it was also kind of ringy before in the spill area but the tiny reflector seems to have tamed that.
At any rate, there’s new and exciting breakthrough’s happening all the time, while Nichia is picking up their platform Cree is making new tiny emitters in the XQ class. Pretty cool stuff going on!
Forgot to post this earlier. :zipper_mouth_face:
