Teaser XML-3 Coming 5A rated

djozz:

Cree has provided a design example (a torch ) for the XM-L3 that seems to show not too much tintshift over the beam, but a pic of a headlamp does not look good qua beam.
Document Library - Cree LED

It’s NiteCore TM06S which they make out to be way more nice than it really is with the XM-L2.

Actual beam of the flashlight with XM-L2.

What they show XM-L2 looks like in the TM06S, basically a crop of the hotspot only.

Considering that most of those type of reflectors always have all kind of bad artifacts, seems like a poor choice of testing their own LEDs on how they perfom, even if that was is not what they were trying to point out.

Marginally lower Vf than XM-L2.
At least now we know that it’s really not a flip chip.
Dome appears slightly smaller.
It’s slightly throwier, delivering 8.3 cd/lm rather than 8.0. The die might be smaller.
Huge CCT shift with current.

There’s a product page with a datasheet already:

XLamp® XM LEDs Archives - Cree LED

The first generation XLamp XM-L® LED was the industry’s first single-die LED to deliver over 1,000 lumens of light output. Newer generations of XM-L expand upon the performance advantages of the XM platform with more light output, better efficacy and...

chip looks good

its bright but no testing done yet, I got some U4 1A and 1B bins
Cheers

interested in results!

Great news

Kaidomain sells them as well

Looks like they only have the 6500K version at this time. I more fond of the 4000K tints personally.

Since there are both visible bond wires (so not flip-chip) and clearly phosphor over the entire pad, could this and the recent “XP-G2 HE” be using the same design and production process?

Could be, I do not have high expectations. But I will do a quick test when I get a couple in from KD.

Rolz · 2020-07-16T08:24:36.000Z

It will be really interesting to see how they perform. Great to see XM-L3 come out.

Rolz · 2020-07-16T08:43:42.000Z

Just saw a flashlight on KD which uses it,

http://kaidomain.com/KDLITKER-C21-Cree-XM-L3-1800-Lumens-5-Mode-LED-Flashlight?search=KDLITKER%20C21

The listing has errors but assuming it’s a L3 and the driver produces 5A, the 1800 Lumens is probably accurate

Excited to see your results, now that I think about it I don’t think I ever really saw any input on how the XP-G2 HE performed at all either, know of any tests/beamshots?

I have a XP-G2 HE but never tested it. I have become a bit test-tired over the last year.

Looks good? Not sure. I'd say looks yellow.

No further comments yet. O:)

Wellp, maybe you could renew interest by taking a different, casual and more relaxed testing approach? Testing a few emitters in a row can save effort, imho.

Sirstinky · 2020-07-17T00:31:02.000Z

Very yellow. I suspect the Cree rainbow with this one too. Hopefully it makes up for it with a nice beam and putput.

I got one from KD also but I don’t recall even taking a close look at it. I guess I was not optimistic it would beat other emitters so the motivation was just not there to investigate it.

Understandable. Your testing is always quite thorough, and has been an incredible service to the community for free. The time invested in proper testing is pretty significant. I thank you for all the tests you have done, and would never take them for granted nor expect them of you or others.
