XHP70.3 datasheet
https://www.cutter.com.au/product-category/led-emitter/cree-led/cree-xlamp/cree-xhp/cree-xhp70/
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!
this is very useful data, thanks
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.
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.
Yeah page 41 there is the internal diagram, it’s still 2 string of 2 LEDs in series for the 6-12V version.
The 3v is a specific version, only the the standard version can be run as 6 or 12 on a dual board ie
cheers
wow sweet! really looking forward to this!
Broken link? 403 forbidden
Weird, that link works for me.
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
… And I still haven’t managed to open my R50 
Is that you whom already took 10 ? 
Let’s hope they have a decent tint and low angular tint shift.
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
Can’t tell if the die is smaller or the package is bigger compared to Gen 2.
They finally have an ETA on the 5000K XP-P LEDs as well: 2021-09-24… two more months.
I had been fairly optimistic about this LED, having a < 6500K thrower LED finally (and a ubiquitous 3535 footprint to boot). But JaredM has shown some discouragingly high vF values compared to the Osrams.
JaredM's data is higher Vf that the CREE spec shows, but the spec is still fairly high. Basically this is a 4 amp max LED, maybe on an absolute fresh cell, or by boost. The throw #'s look decent though.
