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?

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.

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.

[Evgeniy]

@clemence

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

When you will receive these 9080 sw40 LEDs ?

[clemence]

I really have no idea

Just got a-not-so-pleasing info from Nichia:

- No stock for all Ra9050 and Ra9080 219B/C series. The lead time could be anytime between 1,5 - 2 MONTHS!

• Nichia headquarter decided to (temporarily?) stops the sw45k production. Don’t know why. 4500K has been a rare CCT in Nichia these days. My earlier sm453 9050 144A purchase delayed by almost a full month. Then I only got sw45k 9080 219B in limited quantity.
  I’m still trying to get whatever stock left there.

Correct, reservations can not be made until the new Group buy thread is posted and then it is on a first come, first served basis.

A link to the new thread will be posted in this one I am sure.

+1 Correct!

[kaybi]

Welp, now we wait a few months for new stock on the 9080 219b, and some sm503 219c.

After seeing maukka’s results, the sm503 219c could almost be binned as 9080. And the results for the 219b 9080 are nothing short of spectacular.

Is there any data or cri tests for the 319a emitters?

[sixty545]

@maukka

With a reflector I measured significantly cooler color temps (about +700 kelvin) from the hotspot

I am pussled about that if you mean cooler than the spill. I would have expected the opposite?
Is’nt the hot spot supposed to be warmer as the reflector collects the (sideways) rays that have passed through most yellow phosphor?

[maukka]

All the Nichias I have tested have a cooler hotspot than spill. Cree is opposite. What I meant that the difference was larger than with the 219 series. This might have something to do with the two stage reflector of the TM03 (which also hides any egg yolk effect djozz also mentioned). I tested a 144 series led with a normal reflector (from the X6) that produced the warm yellow center.

[sixty545]

Thanks Maukka, interesting viewpoint.

BTW have you noticed that the sm403 turn rather green at high currents (specs), the opposite of the other smxxx and of Cree diodes.

[maukka]

Here’s a 219C CRI90 sm403 on different currents in a Thrunite TC12. Doesn’t change much in tint.

[djozz]

Looks like proof of pwm

[maukka]

No PWM on the Thrunite.
