CREE NX Technology and XD series LEDs

The future is possibly brighter than expected! Let’s hope this new platform is flashlight and DIY friendly..

Not a lot of real info seems mostly marketing talk now.

Small bright LEDs , easy to reflow and combine is what I take from it. But because it seems geared at combining to make street lights and such idk how much flashlight use they’ll have.

Let’s wait what type of leds this leads to. I’m pretty optimistic about the story, the technology sounds really good and has the potential of very small die leds with high output like we want for flashlight use!

I think The Miller is right. This marketing poster doesn’t give much info. And it doesn’t seem to be much of a revolution in LED tech – more like evolution along the lines of where Cree was already (seemingly) going. But, as djozz said, if it results in smaller, more lumen-dense emitters, it may still be a move in the right direction for flashlight use as well. We’ll just have to wait and see. I hope they get that first one out (for a reasonable price) pretty soon, so somebody here can test it and dispel some of the mystery!

Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone.

Interesting. It reminds me of the Nichia E21A and E17A’s compact package design and ability to be placed close together. 264 lumens/mm^2 isn’t that high if the die area is being considered, but is much higher when instead the package area is being considered, which is probably the case here. Hopefully the die will extend to the edge of the package and can handle a lot of current. This would enable us make large area high surface brightness “single die” emitters, like the XHP35, but as big as we want.

Another 4 die LED. Extreme density.

Cree did not provide many details about the first XD16 LED due on the market. We presume that the 16 refers to a package measuring 1.6×1.6 mm. In the current Cree portfolio, the XD16 might be considered in the same class as the XQ-E LEDs. White XQ-E products top out at around 334 lm. Based on the stated lumen density levels, the new XD16 LEDs might hit the 800-lm level.

What may be interesting is if these can be tightly packed and allow us to customize 1×1, 2×2, 3×3, etc die sets all in parallel if we so choose.. assuming 800 lumens/emitter then we could have ~7000 lumens out of a ~XM footprint at 3V and domeless?? Just speculating.. We’re allowed to dream right??? Party

It it may be installed in M43 like flashlight,several dozens of it with active cooling…with 4*20700…mmm

“264 lm per square-millimeter”
but that’s not the highest like they say, the flat black is 1×1mm and does 300-400 lumens stock, and can do close to 800 when driven near the max…

Hey, how are you? :)
