Here is comparison, new on top, older on bottom.
I remember reading somewhere that the 219B was ~7% brighter.
I have the 5000K version shown in Chloe’s diagram in my Texas Poker. White light, not the warmer HI CRI version most people associate with the 219. It’s substantially brigher and has a nice throw. I had to go out of the way to get it when Fred was making the Texas Poker, but I’m glad I did.
I have 2 Triples in the High CRI version and 1 single, and while it’s fairly true that colors look good under their light, I much prefer the white light of this 5000K version. I believe the distinction is NVS instead of NCS. Never have fully understood it though. It’s supposed to make some 475 lumens at 1500mA.
They appear to be coming out with the new version of this that maintains the Hi CRI while producing this higher lumen output. Competing straight up (or attempting to) with the XP-G2.
If I’m not mistaken, they are showing in parenthesis that it makes 155 lumen at 350mA. 290 at 700.
That comparison shows a central heatsink pad that is narrower than the 'old' 219, would it still fit a xpg-board?
The 219B's pad arrangement looks pretty much the same as the 219A's pad arrangement. A diagram of the 219B pads are page 101 of the catalogue.
Lead time is a while. We've been eyeballing these for a bit already.
I don’t really see the advantage over the previous model, what am I missing? I really really like the NVSW219AT I’m using now, at a stated 5000K and some 294 lumens at 800mA, it suits me very well. So where would be the gain in the B model?
Regarding the smaller diameter dome. I wonder if it interacts with reflectors differently.
Essentially it's more efficient.
Did nichia give a rough estimate on lead time?
No solid delivery date yet. Expect several months.
The 219b has a bigger dome, looking at the specs of both emitters.
The new dome looks very much like the xpg shape, more shallow. Perhaps it is also less easy to knock it off then :-)
Chromaticity coordinates (0.434; 0.403) correspond to SW30 group (3000K).
Too warm. Maybe eventually they will become cooler.
You're looking at the wrong info.. or I just don't have a clue what you are talking g about...
I think we are talking about the newest R85, which is not warm.
edit... alexgt..youre right.. its warm 
I’m looking at the catalogue you’ve linked and at the screenshot from it that Helios has made.
The chromaticity coordinates are clearly stated for R85. You can determine the color temperature then by yourself using the chromaticity chart
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…
