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

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.

There are some:

Raylight Pineapple Brass 1xAA with Nichia 219C 4000K R9050

Zebralight SC64c with XP-L2 4000K 90CRI

The Zebra is not cheap though.

I have that same H600Fd III. Itā€™s wonderful

maukka, do you have any measurements for the new LG leds in the Jaxman E2L? still deciding whether to get the warm white nichias or the neutral LGs in the Jaxman e2l but i wouldnā€™t decide until the numbers are out from maukka :nerd_face: .

Should get the LG today or tomorrow.

The real question is how will they act in direct drive :smiley:
Curious to see the numbers as well

Almost sure they are far away from modern cree and nichias.
This is typical feature of LG and Samsung leds - they are very competitive at 350mA test current, but with current raise they look not so good. I suppose the reason is internal thermal resistance.

Thermal resistances:
LG H35F0: 2.5Ā°C/W
Cree XP-L: 2.2Ā°C/W
Cree XP-L2: 2.2Ā°C/W
Cree XP-G3: 3Ā°C/W
Nichia 219C: 4.2Ā°C/W
Cree XM-L2: 2.5Ā°C/W (but with much bigger footprint)

So they are all very similar in that regard. The XP-L2 tolerates a much higher maximum current though because of the flipchip design.

Brightness @ 3A (LG doesnā€™t state the temperature, I assume 25Ā°C):
LG H35F0 4000K: 882lm
Cree XP-L2 U6 4000K: 1000lm
Nichia 219C D240 4000K: 800lm
Cree XP-G3 R3 4000K: 910lm
So the XP-L2 is indeed noticeably more efficient (13% more lumens, basically two Cree Bins). Even the XP-G3 is brighter.

The LG LED still has some benefits though:

- cheaper and easier to get compared to the XP-L2 90CRI (Mouser is very expensive for low quantities)

  • larger Die size compared to Nichia 219C and XP-G3 => more useful Beam in some lights

Does anybody have the datasheet of the LG LED?

Thanks for the ideas :+1:

I must admit, I was very tempted by the Reylight, but the 4000K colour temperature put me off in the end.

Iā€™ll be looking forward to seeing your data :slight_smile:

I hadnā€™t even heard about this LED until I saw this thread!

BTW what about some Osram Oslon SSL LED with CRI=95, R9>90, R13>90? :smiley:

Havenā€™t tried Oslon SSL, but I did test one Osram Oslon for Chouster some time ago. It is hideously green regardless of drive current.

Oslon Square 4000K CRI min: 90, CRI typ: 95, R9 typ: 90
GW CSSRM1.BM-MPMR-XX55-1

This is in a Thrunite TC12 V2 with an SMO reflector.

Still waiting for the LG.

There is no datasheet.
