Am I late to this party or are these new and if so, does anyone have any more information about them? A simple google turned up very few pertinent or relevant results.

So, I did the math. They have one that claims to be 570lm at test current. Test current is 350mA. Forward voltage is 11.3 volts. Claimed efficiency is 144 lm/w. Well, 11.3 X 0.35 X 144 = ~570 so it is accurate. I think 144 lm/w is pretty good. It just doesn’t look right at first glance.
The u4 is at 1200lm at 3A? Xpl at 1000lm at 3A? I’m still in the process of learning! :)So if I sound stupid it’s most likely because I am still not learned!
:) Alright things now get massively complicated (HI, HD, same die different packages, etc). I meant that the brightness of the XP-L HD V6 is almost the same with XM-L2 U4.
These are the official specs by CREE. Keep in mind the U4 should be 7% over the U3, so then the U4 is almost the same as V6. The is no reson to believe XP-L HD is an inferior LED.
Hopefully it is at least a 6V/12V LED like the other XHPs. It looks like a single die though, so it may not be configurable as such. A 11V+ vF LED isn't very useful for most of our lights, since you'd either need 3S cells or a boost driver with 1S or 2S cells.
Am I the only one who thinks, that Cree should focus on 3,xV LEDs?
I mean… 11V for sub 600 Lumens?
That’s 3-4 LiIons, so it will be a big light with little output.
Sure, Cree doesn’t make it’s LEDs mainly for Flashlights - but it’s a not so small part of it.
