More New Cree Goodness coming....

Flashlight Modding and DIY Parts

In ANSI bins (pages 15-17) yes, but in Easywhite bins they are listed with 90CRI down to 2700K (pages 12-14)

Right! That’s a very good news. :slight_smile:

XHP70.3 datasheet
https://www.cutter.com.au/product-category/led-emitter/cree-led/cree-xlamp/cree-xhp/cree-xhp70/

31

Comparing XHP70.3 with 70.2 I see:

  • Much lower thermal resistance (0.2K/W vs 0.7 K/W). I also note that now they measure according to a JEDEC standard. XHP70.2 datasheet doesn’t mention that, so measurement methods might be different and so - the numbers might not be directly comparable
  • Vf changes a little less with temperature and is marginally higher
  • Again I see that these tend to have 1 bin up
  • Light emission is slightly narrower, FWHM is 120° rather than 125°.

Thank you welight for these datasheets!

32

this is very useful data, thanks

33

Also from the XHP50.3 data sheet, “configurable to 3 V, 6 V or 12 V by PCB layout”

Finally, one emitter covers the entire voltage gamete. Why didn’t they do this from the beginning? Im looking forward to trying out the XHP50.3 HI in a few older flashlights that need upgrades.

34

With the 3V and 6V LEDs having the same pad layout, I don’t think that’ll be the case.

Anyhow, looks like we’ll have an updated 70.2 that’s a little throwier, and a 50.2 that’s much throwier. This will probably be a simple reflow to make the FT03 and other 50.2 lights a lot throwier without sacrificing too much output. Double the intensity as previous xhp50 iterations as they said.

35

Yeah page 41 there is the internal diagram, it’s still 2 string of 2 LEDs in series for the 6-12V version.

36

The 3v is a specific version, only the the standard version can be run as 6 or 12 on a dual board ie

cheers

37

wow sweet! really looking forward to this!

38

There’re all listed on Mouser but only high MOC and nothing on order.

Broken link? 403 forbidden

40

Weird, that link works for me.

41

I hope to see some of the new emitters soon that we can buy!

XHP50D-H0-0000-0D0UH245G expected dec/08/21

XHP50.3 HI flux H2, 90CRI, 4500K, 3-step

A surprise to be sure, but a welcome one.

LOOOL

I just placed them in the cart when I went to BLF just to see your comment

44

… And I still haven’t managed to open my R50 :cry:

45

Is that you whom already took 10 ? :smiley:

Let’s hope they have a decent tint and low angular tint shift.

46

Yes I did. Regardless of impressions, I have JoshK Delete Green paint for glass lenses that greatly improves the beam.

But I'm sure it will be good

47

Can’t tell if the die is smaller or the package is bigger compared to Gen 2.
