Nichia 219B 4500k D220 9080 CRI Emitter output test by Texas_Ace; Amazing tint and CRI! Output is what you would expect.

Unfortunately they do not solve the spectral errors of our luxmeters :frowning: , but they give a better absolute output reference than a couple of ANSI-rated flashlights.

Im planning buy some of this leds (when available) and build a single and a triple.

Anyone know whats the best way to proceded in DD with this led?

I know that the best is to stay around 3-3,75 Amps. Max 4. So… 10 to 12 amps in triple.

So, whats the best configuration for stay in this margen at 10-11-12 amps?

For wire i think that 22awg its the way (not 20awg)
For driver spring i think that steel (default convoy) without bypass.
For tailcap spring i think that steel (default convoy) without bypass.

And finally for the cell ncr18650ga? 30q will be too much? vtc6?

Any info?

Open to opinions :wink:

I built a triple with these awhile back and just did it like any other triple. I think I used 22awg. I have no issues with it over driving the LED’s since the Vf on them is pretty high.

Hi, i have some question
you measured the AMPS at max?
You bypass or not bypass the springs?
Cell?

Thanks for your help! :slight_smile:

Yeah, I forgot what the messured amps were but they were not anything to worry about, around 10 amps IIRC. I generally use GA’s in my personal lights but I generally test with 30Q. Either way it should not be an issue with a triple. Even if they are overdriven some it will not hurt then and it will quickly drop as the battery drains.

Where can these LEDs be purchased?

Last I knew they were out of production but maybe Clemence has managed to get more? I have not been keeping up with his stuff lately.

Maybe somewhat unrelated but some nice high-CRI Osram Oslon emitters can be bought at pargos-shop.

Hope I can try some in a near future.

Cheers ^:)

Got a link to a specific item? I just seen 1400 listing of random electrical components.

First of all thanks for your help. You not mentioned but i supose that the 10 amps (aprox) is with bypasess springs right? I think i will go with 22awg and phosphor bronze springs for driver and for the tail. And lets see whats the measurements are. Probably stay in 8-9 amps and thats will be perfect because from 9 to 12 ( in this led) its not much gain in lumens but more heat.

What do you think?

I think that it is not worth overthinking it.

I learned early on that you can’t even see the difference between minor changes and even some major changes with the human eye. So why stress out over it.

For example going from 2.5A to full 6A turbo on an XP-L is hardly noticeable in the real world unless you see it side by side.

I would just build it with whatever fits and works in the host the best and then enjoy the results.

You won’t kill the LED’s regardless in a triple setup with a good thermal path which is the most important thing.

You are right, the thermal pach should be ok (convoy c8)

Thanks for your help.

There’s a positive and negative side to the high CRI Oslon Squares in that shop: the negative is that they show a second generation led in the picture but the leds actually on sale are in fact first generation (with clearly lower old-school performance), the positive is that the first gen. Squares have way better tints than the second and third generation (green :confounded: ).

Mmmkay, some pre-made custom search links from pargos-shop:

There are many high-CRI offerings. I also wonder about the Golden DRAGON series, funny packaging!

Cheers ^:)

What kind of output do they do compared to say a 219b?

Search Ebay for “Oslon CRI 96” and you’ll find them.
They also have CRI 95
Shipping to USA is probably like $12.50 though…

I can confirm the tints are lovely.
I gues they’re better than R9050 too.
The 5730 0.5Watt “E5” in CRI95 are very nice too, by the way.

Not much of a problem for me with output, djozz. I was probably going to use them for some low current flashlight mod or small home lighting project, DIY stuff just for the sake of beautiful light.

I was already noticing v1.3 and v1.0 led versions the other day while inspecting the LCW CQAR.CC and GW CSSRM1.BM datasheets a few days ago.

Their COB emitters look really good for home/business lighting.

Cheers :-)

they came from here, what you see is what is left

last I heard,

I hope the Volcano does no harm

I hope to learn if there is an Osram option that is as good as the unobtanium sw45 9080

I have just one sw45, thanks to a generous member… it is in my pocket as EDC since it arrived… makes my hand look nice and pink, though the beamshot shows an unusual amount of violet in a photo, and Im not sure what to make of it, I really like using the LED, it is very “white” in the evening, not too yellow during the day.

(tint is relative to white balance) in this iPhone photo the auto white balance seems to have decided the 4500k N219b Worm is the white balance reference:

Hey Jon,
someone just posted a pic of a black tool AAA they got with a 219C

I have one on the slow boat to me also. will see.
