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.

:)

Does that mean you’ll be stocking them soon?

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.
