Hopefully in the next weeks. Since the first sample was destroyed while testing I have to reflow and test another one.

I just ordered several of these (and a 6500K to try). These seem very promising - much better performance than the FFL505A and much better efficiency than the SFT-40 3000K. I have recently started playing around with those other two LEDs so Iām really looking forward to these LMP ones. Thanks for the test!
Which is not surprising at all since the FFL505A is way too reddish and the SFT-40 3000 K has also the problem due to high CRI. Lower CRI emitters are always better than itās high CRI counterparts (except for those with horrible flux binnings)ā¦
That my first sample of 6500 K burned is not a good sign. There was no flux residue on the LES. It looked more or less the same as with the XHP50.3 HI I tested last year.

I saw that you posted results for a 6500K variant in the FFL 6500K test. Do you mind sharing any further details you may have, such as cd/mm2?
Currently I only have these light flux data. I donāt have the time to test every single variant of a certain LED, especially since there are hundreds or even thousands of LED types with various CCT and CRI binnings out there. Sorry for thatā¦
(Perhaps I should refrain from testing individual variants after all. I simply have less time than I used to, and I donāt think that will change in the long term. The luminance measurements in particular eat up a lot of time because of the test setup, and I simply canāt manage to run the complete test setup for individual LED variants, even with a shortened test report.)

Totally understand!
Idea: If you could just share a csv/table of the lumens, Vf per current when you do a test, that would go a long way! I or others could then post comparison tables/graphs to follow up on your test, saving you some time.
I thought about this already. But I fear that some people just steal the data and bring them as their own. Not everyone in the flashlight business is fair to others people work. For now copying data is much more difficult. (Stealing content from my tests was already a thing. I look at you, random Chinese Aliexpress seller!! 
)

Thank you for already thinking about that. How sad that some actors abuse this.
Well, thank you so much for all your work and sharing, it has been immensely helpful for designing my mods and to make informed decisions!
This seems not to affect the 3000 K variant, but was seen for the 6500 K variant:
burning of LED silicone / phosphor.
It is not recommended to drive both variants above 8 Amps for normal use. In my test the 3000 K variant was not damaged after reaching maximum operating current, but maybe this was just luck, who knows.

At which current did this occur?
I just ordered a few 6500K variants to use with 8A drivers, hoping that few may be issue-free.
This burning thing occured at around 8 Amps, so I cannot recommend using the W5050SQ3 with 8 Amp driver.
