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

[Still in the off-topic, shortly, and sorry to respond here too: you can ask Simon to send different lenses on the same package, instead 5 of the same kind.
The TIR lenses for XML2 fit the XPL-HI (I tried in the S2+ Desert Tan with XPL-HI) and used the TIR, without the plastic holder, with the AR coated glass lens above it and with sealing o-ring as well. The beam produced with “pebbled” (hive) lenses are much similar bewteen XPL-HI and XML2 - both are floody - but the XPL-HI seems to have a more bright centre and smaller overall angle in outside diameter. The other lenses, tend to reflect the type of LED that it has below, being narrower with the XPL-HI and floodier with the XML2.]
Back to topic :wink: :arrow_right:

I’d also like to thanks Jaxman for bringing these LEDs to our attention. Too bad they weren’t any good, but like others, I’m happy that we got the chance to check them out.

Hey, anyone have one of these lights yet? Are they glued shut?

I’m tempted to pull the trigger on one, but worst case, I’d just swap emitter boards (no reflowing). As long as I can, that is.

Is the 4000K version that horrible? The beamshot on ali makes it look almost rosy compared to the 5000K.

I asked no glue. But they didn’t even put thermal paste between the MCPCB and shelf…

Doesn’t really matter in this case, but still.

Jaxman only sells the 5000K version so I can’t tell.

Yeah, I didn’t look hard enough. :smiley:

I saw the comparison pix, thought that in the 2nd pic the 2 ideographs were just Chinese for “LG”. :smiley:

Only when I tried the option as if to order it (to see if the prices were the same for 4000K and 5000K), that only 5000K was available.

The LED on the right is identified as being a Nichia in other advertising photos.

Ah.

No thermal compound? That’s not good, especially when JAXMAN has a picture on their website showing that they apply (too much of) it.

That is very strange. I have a JAXMAN E2L host that I think is top notch, so I’m not trying to bash them. I’m just dumbfounded.

Maybe JAXMAN considers this as “glue” and since we requested that they not glue their flashlights, they decided not to apply this “heat conduction glue”?

I prefer that there is nothing in there

The glue that uses JAXMAN is ceramic type
After curing, there is no way to remove it if is not with a chisel or an emery stone

Hey, well crap, i bought 2 triple boards of these…
Not in yet…
In fact, waiting for many orders a.t.m., as if the postal gods are not on my side lately…

Same here, packages are not arriving at all :frowning: maybe Chinese holidays consequences ?

Urgh. I officially withdraw any interest in lights with those LEDs.

It really goes to show how much R&D effort Nichia must have put in to create their 219A/B/C LEDs, though.

Thank you for the test data, maukka. It’s much appreciated.

I’d also like to join previous posters on this thread and add my appreciation to Jaxman for giving us a chance to find out about this new LED. No luck this time, but he didn’t know that beforehand. If things had turned out differently, he might have been handing us the next big step in high CRI lights…

Man, it’s unfortunate that I bought a triple mcpcb with this led before the tests showed up

You say that twice, i ordered twice the triple board… :person_facepalming:

I think it’s very nice of most of you to thank Jaxman for the opportunity, but i feel quite disappointed…
Jaxman has a reputation of good tints, which may be easy when you use Nichia LEDs.
But i didn’t expect this LG LED, when it’s an ugly tint, to be sold by Jaxman.
So i expected a nice LED, not a greenish tinted one.

But it is what it is, can’t win ’em all…
I don’t blame Jaxman, but i just expected better.

For photography, the LG H35F0 could perform quite well considering its overall score to TM-30-15 standard despite its Duv score.
2 LG coupled in a quad with 2 nichia 219C 5000K could be nice as they are quite complementary for better colors fidelity. The nichia lacks of blue fidelity compared to the LG, and this last one lacks of red fidelity.

MF-01’s Nichia:

E2L’s LG:

Not too shabby.

EDIT : both superposed in Gimp to show the highest value for each 99 samples, could be different in reality, but the Rf score (average) should be higher than the bar on the graph :

So what you all is saying indirectly is that jaxman photoshopped the reference photo (the one with the LG led and the Nichia led side by side) or used a bad camera or whatever that makes the photo not describe what the light of that led looked like?

Or

You never looked at the photo and now when you got and see how it performs you get disappointed?

Or am I missing something here?

Next time someone tries to introduce a new led you all should ask for some more beamshots on different things or something…

.

Don’t recall the ratings, but you’d need to make sure the Vf for the 2 types is a nearly exact match, else the 2 with the lower Vf will be almost fully on and the 2 with the higher Vf will be pretty much off (applied voltage below Vγ).
