New led Cree XT-E

I think the real advantage of these LEDs is their price, perhaps now we will start to see some of the cheaper lights coming out with these LEDs rather then some of the less efficient LEDs at the same price point.

and maintain output at high temps

that will be interesting

once we can find one on pcb, anybody else want to chip in on sending one to Match?

I’d chip in

Looks like NO-ONE has the XTE in any type of white in stock yet. Checked All the usual suspects - Mouser, Digikey, Arrow, Avnet, TTI, etc..

Give it a little time.. Probably not 'really' released yet. Maybe a few LARGE volume CREE Customers are getting them, but the distributors aren't yet.

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€

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.

XT-E = $3.17 at

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.
