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

Can just post the one for LEMWE33390HU5000 to. You see the ā€œHUā€ specs say 3A max and ā€œSUā€ is 2A max.

I guess the number after the 333 is for the CRI.
So LEMWE33370HU5000 is for the CRI 70 led.

edit: those numbers was only for the CRI 70 led (but the 3A max is the same). See original post for numbers on the CRI 90 one.

Thanks djozz! It seems efficient enough to think about using it.
Can you maybe do some more testing with reflectors and/or optics? :wink:

Clearly, CRI isnā€™t everything. The CRIs are excellent but as youā€™ve said, the tint is hideous. Anyway, I just hope the LG isnā€™t like that.

Mine arrived yesterday. I donā€™t have any quantitative test like djozz can provide (yet), but I did toss one into one of my standard setup P60 drop ins (5x7135 QLITE, OP reflector) just to check out the beam and tint. It isnā€™t great.

Tint I would say is on the slightly greenish side, but pretty good overall for >5000k. The real problem is the beam. Serious ā€œfried eggā€ in the hot spot. Right in the center of the hotspot is a very noticeable yellow, then the rest of the beam seems a consistent color. This is in all modes. I havenā€™t tried with a TIR yet so not sure how that would look. Looks decent as a mule though.

Ai, I had seen that spiegelei correct then :frowning:
I had ordered a complete E2L with this led some time ago, so will wait for that one for my TIR-verdict.

LG E2L waiting in the post office. Looks like they donā€™t really work with reflectors so maybe testing them inside the light is sufficient for now.

I hope they look better when used in triple or quad configuration with TIR optics.

I think itā€™s fair to say that this is the most disgusting LED in a flashlight Iā€™ve seenā€¦ (ok, maybe an exaggeration).

Just look at the green/yellow tint, which varies all over the place in the beam.

The cellphone beamshot doesnā€™t convey the true horror, but gives an idea of the shift within the beam.

Thanks Maukka, very interesting!
This is the first LED with a high R12 (deep blue) value, but CRI of only 89-90 instead of 95+. Orange (and green) is dominant in the spectrum. Purple is weakest. Skin probably doesnā€™t look so great?
Itā€™s also interesting that the color temperature is much lower than stated.

Manufacturers spec the CCT integrated not from the hotspot with optics/reflector. This is the light in an integrating sphere, which is probably within spec considering drive current (E2L on high, edit: color temp is same on mid, tint a bit greener):

Well yes, they measure it straight on, so basically the spill of the flashlight. 800K difference is still a lot though.

Output and tailcap currents:

Low: 19 lumens, 71mA
Mid: 174 lumens, 660mA
High: 589 lumens, 2200mA

Total flashlight efficiency is then about 65lm/W on high.

Yuk! :confounded:

Thanks for testing maukka!
Now Iā€™m not so looking forward anymore receiving the E2L with these leds.
Perhaps these leds work well in a mix with very rosy Nichia leds.

Hmm. Maybe of use in a wide-spectrum light.

Difficult not to agree with Maukkaā€™s evaluationā€¦ā€¦
ā€¦ā€¦.Hopefully they come packed in air sickness bags

*what happened to Jaxman ?
Did Clemence scarf up all the good Nichias ?

Iā€™m not sure its good to imply that something bad ā€œhappenedā€ to Jaxman. They took a chance on a new and unknown LED and I applaud them for that. Taking risks is how awesome new stuff gets foundā€¦sometimes. :slight_smile: Its also how a company can set themselves apart from the competition. I mean now we know these emitters donā€™t have good tint, and we know that because Jaxman took a chance on them. I, for one, appreciate that.

I agree, I bought six of these emitters just to try them out, after seeing them in person, I know I donā€™t like them, but that isnā€™t the fault of JAXMAN. The JAXMAN lights are still the same top-notch lights, maybe just skip the LG option.

I applaud them for making the emitters available. Plus, they would still work OK for lantern duty in something that doesnā€™t have optics.

Thanks for this maukka. I am disappointed by the low R9 of the LED and I am happy for not impulse-buying the E2L even for its low price. To be fair to be LG, Creeā€™s lineup have consistently low R9 performance and are also known for their green tints. I guess Nichias are a safer (if not safest) choice for general use with reflectors and TIRs.

This is a deal-breaker for me. I am tired of looking at greenish beams and I am quite happy with what Nichia has been giving so far. The only problem with Nichia LEDs is that they are not available in the tint and CRI combination that I am looking for.

The proper industrial nomenclature is barf bag! :laughing: LOL, just playing! :innocent:
