LG high CRI LED E2L flashlight-maybe this LED is unknow to everyone..

Has anybody received these LEDs yet and tried them out?
How good is the R9 rendering (deep red) compared to Nichias R9050 LEDs? I think that is the first thing we need to know.
After that it would be important to know if is produces a yellow corona when used with a reflector.
The tint is of course also important.

I’m still waiting for them to arrive.
I expect a yellow corona in a reflector at least as much as an XM-L2, but i’ll be using them with TIR optics.

I have them in house but did not come round to doing anything with them. I can do an output test and visually evaluate tint (including how good the red portion is) but can not measure tint, let go R9.

Great, thanks!
Yes, I meant a visual test. With enough experience and some lights to compare it to more is not needed.

Can you try this way?

I have a Lee filtersample-book, with transmission spectra charts, so yes, I could try a few things.

But to be honest, what ultimately matters is if the tint experience is good. Every led that maukka tested for tint and CRI thusfar closely matched their specifications, so to check if a 90 CRI led really is 90 CRI is not needed.

Hello.

Nice to see new High CRI LED, but why no one use Cree High CRI LED?
E.g. XPLBWT-00-0000-000UU650G is XP-L2 90 CRI 5000K LED with 132lm/W…

Zebralight SC64c does.

I have studied the picture of the LED LGs website more closely. It actually seems to have bond wires, so it’s not a flipchip LED. De-doming might be a nice option here for some people.

I have done a sort of attempt to dedome a Samsung led in the past and that was a fail, at least it is a lot harder to do than Cree leds. LG leds seem to be technically related to Samsung leds.

Correct me if i’m wrong, but high CRI does not necessarily mean great values in the red part of the spectrum.
And from what i’ve read about Cree high CRI LEDs, they don’t have as much deeper red as Nichia high CRI LEDs.

Even when the tint is to the red side, real deep red is not necessarily there.

Maybe those XP-L2 you mention are just as good, i don’t know them.

Actually the newer Cree LEDs (XHP-50, XHP-70, XP-G3, XP-L2, XHP50.2, XHP70.2) with 90CRI are just as good as the R9050 Nichias in this regard. I have lights with both and measurements from others have shown this as well (Maukka for example, see here). :wink:
Of course the Nichias have better tints though.

dont think you are right
219b can have 90+ R9, still unbeatable for any crees.

I wrote R9050 Nichias. ;)

The 219Bs are very inefficient and have a low maximum lumens output. The current 219Cs are not available with R9080, only R9050. Also they don't offer an XP-L2 sized LED. That is why this LG is so interesting.

There is also the question of what we actually need. A R9 value of >=50 is already very good. It makes all the diffference in the world compared to LEDs of the past.

I find that R9080 Nichias make the R9050 Nichias look like Cree…
You notice this especially on human skin.

I know, I know. But outside the difference is not as pronounced. Depends on the application.

That’s true.
It’s not always that important.

I know sample size = 1, but I have a high CRI XP-G3 and find it very ugly. Yes the CRI is there, you can tell it if you look for it, but I’m so distracted by how green it is that I have to really try to see the nice color rendering.

It seems to vary. I have 4000K 90CRI XP-L2’s that are as green as you describe, while the 80CRI variant of the same led has a great tint. The 3000K 90CRI XM-L2 leds that KD sells again have a wonderful tint.

I have several CRI80 and 90+ XHP50/70 and none of them look as good as the Nichias because of green or yellowish muddy tint.
