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

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/Wā€¦

Zebralight SC64c does.

I have studied the picture of the LED LGs website more closely. It actually seems to have bond wires, so itā€™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 iā€™m wrong, but high CRI does not necessarily mean great values in the red part of the spectrum.
And from what iā€™ve read about Cree high CRI LEDs, they donā€™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 donā€™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 Creeā€¦
You notice this especially on human skin.

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

Thatā€™s true.
Itā€™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 Iā€™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-L2ā€™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.

I have some 80 CRI 3000k XP-L2 which arenā€™t too bad, lots of pink in the tint. But the 80 CRI 3000k XP-G3 looks fairly green. Iā€™m sure there are good new generation Cree chips out there, but it seems a bit of a lottery right now.

The only amazing Cree Iā€™ve seen so far is the 4800K XM-L2 EasyWhite (quad die) in the ZL H600Fd Mk3. Even if it is CRI 84 R9 19. The frosted lens makes wonders.

This is going off-topic, but I recommend shaving or de-doming the first generation high-cri XHP-50 and XHP-70s. It noticeably reduces the yellow corona and spot. The tint becomes much more even.

When will you find the time? :smiley:

Yep, it helps a lot for the tint shift and even makes the tint better on some emitters but I havenā€™t been able to get the tint just perfect. The best one and the only one I would call neutral is a shaved 5000K XHP70 CRI90 in a K60. Beam.

Thanks for replies.
Yes, I know about R9 specifications, but I didnā€™t know, that Cree has so bad tints :slight_smile:

Unfortunately, triples are too floody for me, so the E2L is off the menu.

Any chance of getting this LED into an M2?

That would probably be a unique light in the marketplace, because 5000K and 90 CRI in a cost-effective AA light are very hard to find. Zanflare might be thinking about one, but theyā€™ve gone quiet lately, and the only other option I can think of would be a much more expensive Eagletac.
