Cree XP-E2 flashlights

Has anyone tried a light with one of these emitters?

If so, how do they compare with XP-E's and XP-G2's in terms of throw and beam quality.

Yeeaaah let's. I want to know about some 1xAA & 2xCR123 lights with XP-E2.

:thumbsup:

Re: Cree XP-E2 flishlights

I don't know how you guys keep up with all the Cree led's and I work there every day.

Fenix recently upgraded its XP-E's from R2 to R4 bin in their E15 flashlight (1xCR123), with some 30lm gain. I'm pretty sure that they won't be the first to introduce brand new XP-E2 in their product line...

Cheers

Re: Cree XP-E2 flishlights

The xp-e2 is probably going to be rare. The xp-g2 & xp-e2 received a new, larger, dome that reduces the apparent die size, increasing throw.
The xp-g2 has 10% more output relative to the xp-g, and 10% more relative throw, for 20+% more lux versus 'old' xp-g based lights.
With the xm-l & xm-l2 covering big lumen numbers-but low lux, the xp-g2 should be the other side of the coin.

That leaves the xp-e2 for AAA sized lights...

I did ask at Eagletac if they would make a T100C2 with the xp-e2. I'd like 20,000 lux for 45 bucks.

Re: Cree XP-E2 flishlights

The xp-e2 is good for more than just aaa lights.
More throw for less current compared with a xm-l2 and xp-g2. So if you need a light that is small, throws like a champ, and dont want to screw up the runtimes. The xp-e2 is hard to beat.

Cant wait to see some small xp-e2 throwers.

Re: Cree XP-E2 flishlights

The Fenix E25 is using the XP-E R4, which is the XP-E2. Much better runtime on max.

Re: Cree XP-E2 flishlights

I want to know, too. With emitters getting bigger and bigger the XP-E footprint is needed to get decent throw from a small (AA, AAA) light. I like small lights, but not real floody small lights.

Re: Cree XP-E2 flishlights

i did some messing around with the XP-G2 versus the XP-E2 as upgrades in a LF2XT light. What I found is that the xpe2 does have a smaller spot than the xpg2, but the xpg2 is significantly brighter than the xpe2. The end result was that the spot of the xpe2 was only the tiniest (barely noticable) bit brighter than the xpg2 spot. The overall lumen output led me to prefer the xpg2.

I am sure other lights with different reflector designs will provide varying results.

Re: Cree XP-E2 flishlights

The 'problem' is that the xp-g2 is rated to 1.5 amp and has a thermal resistance of 4 degrees [Celsius] per watt, and the xp-e2 is only rated to 1 amp and has a resistance of 9 degree per watt.
The other problem is that less savvy purchasers only look at lumens, and not lux. Which is only exasperated by the ANSI NEMA FL 1 rating system, which can be gamed.

oh, and the Vf is about 0.2 higher, which works against boost driver efficiency.

Re: Cree XP-E2 flishlights

Good points MichaelW. I agree on the current and thermal limits of the XP-E2.
I don't think most purchases would understand how lux translates into throw be able to correlate that with experience unless they are flashlight nuts like us who buy 20 flashlights just to pick the best 1.

Re: Cree XP-E2 flishlights

The xp-e2 seems to do it's job, even when driven really hard (2,27 amps).
Judging from the pictures in the vinhnguyen 54 ultimate p60 reflector thrower sales thread. :devil:

I'm having Vinh mod an old mini123 of mine with a neutral XP-E2.

Perfect as a spotting light to supplement a floody headlamp when night hiking.

Sorry for the newbie question. If both xpe2 and xpg2 is driven at 1amp, will xpe2 throw futher than xpg2?

XPE2 but with less lumens due to smaller hotspot.
Perfect emitter for efficient pocket throwers IMHO.

The XP-E2 will throw further. It did in my tests.
