Successor to the XP-E . . . am I to assume this would be appropriate for a smaller light?  My understanding of LED technology is limited.

Noobie question...

85C instead of 25C....

What does the "C" stand for?

Pretty much the next gen of XP-E's.

Up to 148 lumen at 350mA. Worth to mention the max rated current is now 1,5A!

Might turn out rather nice. 500mA to emitter from an AA is possible. I would fancy a 1AA 200 lumen flahlight.

Man, that's something to live for!!

Spotted something, the LED die is like 3-D(Not Flattish), very interesting.

When's the XML replacement coming?Undecided

Or the MCE's replacement are coming first...

thought for my day...3-D led lights....

Just hope there's no tint shifting like the last xp-e update.

Would it be good for good throwers with aspherics?

 

115º vs 90º of the XR-E, I am not quite sure..

figured i'd buy one

I just checked cutter and the only xt-e offered on pcb were blue

didn't see anything at mouser on pcb either, though i'm not all that familiar w/ their site

i noticed cutter says brighter and cheaper than xre (but that's in comments for a blue one...)

90 of the XRE is better for a thrower

Love to hear how you get on with that change. My SH-035 turns blue on a 14500. Needs a driver and emitter swap.

 

The numbers from my light tests are always to be found here.

This new LED looks very promising. I calculated that it will outperform an XP-G with around 10 pct. more light at 1.5A and run appr. 8 degree Celsius cooler (both bin R5).

At 1A one can expect 330 lumen Out-The-Lens dropping to 295 when hot.

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.

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 am currently extremely busy with work. Please do not expect a response from me quickly. I will be dropping in as time permits, but the amount of time I can dedicate to responding to topics and PMs is very limited.

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.

This one would have a very blue tint, I guess. Wink

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.
