I'll update about it somewhere. Currently waiting to see the lay of the land for decent 16-17mm drivers compatible with this new piece. Thankfully my SH-035 runs decent off of 14500s but it gets real hot real fast, so I've limited it to NiMH use. But with a TrustFire R5-A3 on my side most often, there's no incentive to ever grab the Aurora. Or much else.
Concur you can get some cheapish XP-G lights but they're still generally at the higher end, particularly for AA. Hopefully we'll get some decent lights with these. And they're potentially more efficient then the XP-G given the different rating temperature.
The price is similar to the xp-g ;)
XTE = 5.49€
xpe = 4.99€

XPG = 5.49€
This one would have a very blue tint, I guess. ;-)
Sure but the color doesn't matter with a view to the price ...
I've seen it claimed in quantities it's about 40% cheaper then the XP-G. And it's still fairly new.
BTW that's a royal blue XT-E which has been available for a while. The whiteys are still not easily available in retail AFAIK.
hmm looking at the led looks like mounds of sand instead of a flat phosphor
My guess is that this is Cree's way of increasing die surface area without increasing the package size.
I wonder what that does to the beam quality.
Crazy lookin'. Check out the green stuff going through the die.
It should make for an interesting beam image when fully zoomed in an aspheric light.
Today I received an XT-E R5 from Kaidomain and installed it in my Romisen RC-G2 (it replaced an XR-E P2).
The output is OK, but I'm not impressed with the beam and tint. The hotspot looks yellowish, the corona appears darker than the spill and the inner part of the spill has a purplish hue.
What do you think, could this at least partly be because the reflector is optimized for the XR-E? Does Cree maybe need a few more months to get the colour right?
you could post a beamshot?
I'm afraid my camera isn't very good at this. I tried every friggin mode and this is the most accurate I could get... On a second look, I think it is pretty good.
that is a great beam shot! so is it much brighter than the xp-e you replaced? i'm thinking about trying one of the p60 drop-ins.
Thanks cabfrank. The output is visibly brighter, but it's not worlds apart.
I guess to really make a difference I would need a better driver. You have to keep in mind that this is a 1xAA light, and with the stock driver the tailcap current is 1.1-1.2 ampere. I wonder what the LED sees of that, maybe 300-400 mA.

might be easier, and almost as cheap, as changing the driver.
I have no flashlight that would take these dropins, but of course you are free to try them out and share the results 
Another member here wasn't overly impressed:

I'm not sure if this qualifies as a beamshot, but maybe it gives you a picture 
It looks brighter in real life though.
