[GB ended,discussion only] CRI > 80+ NICHIA 2000K-6500K [E21A/219B/219C/319A/144A/757GT-F1(Optisolis)]

[RollerBoySE]

Absolutely fantastic results.
Thanks maukka!
I really want to get some of those R9080…

[clemence]

GREAT thanks Maukka!! :laughing:

Looks very good. Especially the 144AM. I wasn’t wrong about them
Interested in testing the 319As and NVSL219B-V1 sw40? I’ll ask Chouster to send them to you later

EDIT: I’m not a fan of 219B tint, but I never thought the CRI result is super amazing. Now I know why this one is so special for you guys.

Great data maukka!

Did anyone yet put a high CRI 144A in a flashlight with smooth reflector yet? My single sample produces an ugly yellow spot in the center of the hotspot, but it has a slightly uneven phosfor layer, perhaps other’s leds are better?

OMD Jos, you use that egg yolk in your flashlight? :person_facepalming:
I’ll get you a normal one later. Which CCT? Let me know

Is there a common way to test the LED without reflowing it? I do not want to start my reflowing career with this emitter… Power supply is available.

No no, don’t worry, this is another led with a much better phosfor distribution. But even a slightly uneven distribution with the phosfor just a bit thicker (=more yellow) towards the center (my led) already produces the effect in a smooth reflector (have not tried OP yet).

Ahhh, I see…
Yes, smooth reflectors aren’t the 144Ax mates. I tried them in my predator’s reflector, many narrow TIRs, big reflectors, etc…always a slightly yellow center spot. Fixed easily with even very mild 5 degree diffuser. All medium, wide, and diffused optics worked great. I’m sure OP reflector will do OK since this the artifacts in 144Ax are much less problematic than XHP50

[chouster]

Very nice test, thank you Maukka!

Results of the 219B-V1 R9080 are stunning.

But all LEDs tested here perform well above specs. 219C sm573 even achieves R9080-specs, sm503 very, very close.

[Jerommel]

Couster, i’ve got my LEDs in too. :+1:
Thanks guys.

[Evgeniy]

@clemence

Yes, There will be NVSL219B-V1 sw45k AND sw40 9080 too

Nice.

interested for 6x NVSL219B-V1 9080 sw40
(or 3x NVSL219B-V1 9080 sw40 + 3x NVSL219B-V1 9080 sw45)

==

thanks, Maukka ! nice tests.

[Jerommel]

@clemence

Yes, There will be NVSL219B-V1 sw45k AND sw40 9080 too

Aha, i knew i would have to order more the next time…
I’ll have to take 5 or 6 of the sw40 too of course… :partying_face:

it’s never gonna end, is it? :person_facepalming:

Ok, I just put the 144A in an insulation gasket and tested it with 50 mA from my power supply (sorry for not taking pictures, but I needed all of my hands):

- With aConvoy C8 OP reflector there is a very visible yellow spot in the center of the hotspot.

- With this 52.7 x 57 mm SMO reflector the hotspot is much more intense and there is only a little bit of yellow seen on a white wall.

I guess that the deep reflector directs more light into the hotspot and thus mixes the colors better. When you optimize the focal distance it might become completely invisible, only I do not have the equipment to try that.

My 144A shall go into a McR-27S reflector that I am currently waiting for. When it arrives, I will appentd my findings.

[djozz]

Thanks for the report tuelleric, it is hopeful that the 144A works well in some reflectors.

[goshdogit]

Thank you to all the organizers/distributors for making these Nichias available! :+1:

I missed out on the first sale, but managed to score a couple of 9080 SW45s and put one in a Zebralight H51 headlamp. It’s gorgeous!

Now I want to fill a Meteor M43 with them. I’m sure I’ll drop some into a few other lights as well.

I’ll need about 15 more 9080 SW45 emitters please!

[Texas_Ace]

I see the m43 being the perfect host for these 9080 LED’s. That way you have enough of them to get some good output and it would make a truly amazing photo light.

I took a few pictures today with my triple 9080 and the color is fantastic. It really does make every other LED I own look bad.

[Gunga]

Got my LEDS today? A couple mods planned for tomorrow. Need to find a suitable host to try the 9080!

[malkoff_junkie]

Is there any beamshots so far of 9080?.
Mine are going into a triple s2+
Thanks.

Got my McR-27S today. The hotspot also has a light yellow center, but not as pronounced as with the C8 OP reflector. Maybe the XM-L gasket that I use does not adjust the 144A in the optimum focal distance. I still have to check that.

[kaybi]

I have not even gotten my leds yet, and I’m already planning what leds to buy on the next sale.

I’d say 6 sw45 9080, 6 sm503… and I’ll leave it at that for now.

I suppose we can’t actually make reservations yet, though, can we?

Also, thanks for all the tests maukka. That r9 value of 97 is insane.
