Preliminary XP-G 2 real word results

[sixty545]

Thanks, that calms me a bit. I was afraid that this new “killer” should be a disappointment just like the XT-E with its yellow beam core (at least my two ex. Had it).
Yes, a 2S tint would be rather green lying a good bit “north” of the black body curve.
I am now anticipating the XP-G2 in tint 3C with a uniform tint, can’t wait…

Cree spec sheet say that the XP-G is better than the XP-G2

[nikanon]

You noticed that these test where run at different temperatures, don’t you?

Edit:
HorstHorstmann already mentioned it.

[Rufusbduck]

When you correct for temp the xpg-2 is better. The specs are a bit confusing here. You have to reference the output vs temp graph to get real world data for the xpg.

[how2]

Thanks for correcting me. I just looked at the numbers.

Are the New XTE any good ?

According Eagletac they seem better

I'm looking for XP-G2 mounted on 16mm star. I know Int O has them but out of stock. Any other venders with stock?

This is no help to you but Cutters only have 18 and 20 mm stars at the moment.

10mm star is also available.

I have the XTE r4-3A on a quad pcb. It has a nice rich tint, not to yellow but not blue-white either. Not ready for beam shots yet, still testing.

Very interesting and good job Match.

I have a question though, shouldn’t the new XP-G 2 be S4 bin since it puts out 20% more light than an R5?

No, because now they are measuring the output at more realistic 85°C. The older XP-G was binned at 25°C and therefore delivered less output than the bin code suggested if it was run for a few minutes.

[Johm]

I see, thanks Erzengel for clearing that up for me.

So XT-E, XP-G2 (and probably all new leds from CREE) are brighter/more efficient than their bin suggests compared to older emitters.

“10mm star is also available.”:http://www.cutter.com.au/products.php?cat=Cree+XPG-2&pg=2

My bad. Yes they do also have 10mm. Must be that senility again that the better half complains about a lot. Thanks for correcting me.

As i have made complete tests with almost all cree emitters,5 cree xt-e that i have, had just like most cree xp-g s2 bin that i had, could not see difference in lumen output@700ma, or one of them in Armytek predator@1,5amper . Xp-g2, is a step ahead, they are better, to about S3-S4 bin rating and focuses much better. Cree xt-e is good in general lighting, as it is cheap and if you are lucky, you might find it good modding some old xr-e led flashlights with this. I personally modded my jetbeam C-Le with a xt-e and focuses great(still some yellowish corona, but very happy with the result).
(again, all leds were from cutter, not advertising, he is expensive, but he is a trustful dealer)

Match,

Anyway, comparing the two C8s, the 2 stomps all over the older XP-G. Interestingly, the hotspot appears to be slightly larger with the 2. Now, here's the kicker: in actual usage (not luxmeter), the 2 appears as bright on medium (1.2A) as the older XP-G on a 2.1 high! I know this can be hard, comparing different tints, but I can see just as much detail on distant objects at 1.2 A with the new emitter.

Awesome news Bob! Gonna have to keep these XP-G2's in mind.

Ditto! They sound great.

[cainn]

Anyone selling these on 16mm stars yet? I know IO were but are now out of stock, but are they currently available anywhere?

[JohnnyMac]

Yeah, Bob, I agree they are best suited for smaller lights like AA/AAA. As I travel down the flashlight road I find my tastes for smaller lights have changed and I am more into all around use, low lows, and run time instead of just the brightest in the smallest size. My appreciation of the XP-G has grown over the last year or two. ;)

Ok...another quick couple of mod results. I just swapped these into my Fenix LDO1 and Shiningbeam S-mini xp-g. My poor LDO1 has had more emitters ran through it than one of foys SF hosts...

Anyways...here is the data (all values are OTF obviously):

Fenix LD01

Battery	Mode	Stock	Mod(xpg2)
1xAAA	Low	2.7L	4.3L
	Med	22.1L	30L
	High	70.3L	93.8L
2xAAA	Low	2.8L	4.3L
	Med	40.2L	48.4L
	High	151.8L	162L
1x10440	Low	3L	4.3L
	Med	59.3L	79.6L
	High	221.3L	347L

ShiningBeam S-Mini XP-G

Mode	Stock	Mod(xpg2)
Low	5.5L	6.8L
Med	111.5L	130.2L
High	237.2*	327.3L

*Stock, high was 274.3L at turn on, but dropped really fast (~30sec). Found too much thermal goop during the teardown... This is why I teardown almost every light I get, just to verify the work.

This was a noticeable improvement over stock. No more green tint, better throw, and more light to boot. This is quickly becoming one of my favorite emitters.

Stay tuned tomorrow for the full emitter test results.

[SashiX]

Wow, that sounds really great Thanks for those tests, Match, really appreciated
Only one thing: can you make white walling but with the same light, i.e. if you have 2 identical lights, one with XP-G and the other one with modded XP-G2. Or just make 2 pics with the same camera settings, you know.
Thanks in advance

[Foy]

Better tint too! Looking forward to the final emitter test. I use your charts pretty much as my emitter/battery/drop-in/lumen bible.
