New 2013 Nichia NVSL219B... typ. 92CRI

Just saw that they have the new NVSL219B R85, (see the text NEW)which has a typ. of 92CRI,
while the older 219B`s were up to a typ. 83CRI.. now they added this as their latest emitter.

but what I dont really understand is that it shows at 700mA,

while the older NVSL219AT-H1 shows all info at 350mA....

what does that mean... ?
Does that affect the way we use them in flashlights?
Does that mean, that they can`t be used with lower currents?

 

edit: I think I was too early with posting this, as it seems that I was wrong, and that this emitter is not the successor of the NVSL219AT-H1....

And rather is a WW with 92CRI.

Wow, hopefully we’ll be seeing these emitters soon.

Nichia’s catalog is very elegant in my opinion. Wink

Maybe you can run it with lower current. Are these brighter output? The pdf is slow for me to navigate on this computer.

That is interesting, the datasheet does not seem to be updated yet.

Must be sw45 for 4500k. Otherwise, in warmer tints, Cree already has +90 high CRI available. XM-L2 +90 CRI.

NVSL219A-H1 specs for comparison.

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.

Did nichia give a rough estimate on lead time?

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 Smile

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 Sealed

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! Smile 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’x19B’ 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=‘... , hope this works! Smile

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 ???

http://www.ledrise.com/product_info.php?info=p1499_Nichia-LED-Series-219-NVSW219A-475lm-Emitter-White.html

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.
