Yes, XP-E2's tested here (djozz): https://budgetlightforum.com/t/-/32354 and here (match): https://budgetlightforum.com/t/-/16621, they peak in the 2.45A range or so. After that, the lumens/throw drops off. I did a 2.8A XP-E2 once, and saw the output to be about the same as 2.45A, but lots of variations from LED to LED as djozz pointed out in his tests.
I wonder what the XP-E2 torch can do in the Jacob A60, if i understand things right if the XP-E2 R3 can do about 220kcd, the XP-E2 torch should be 2 flux bins higher with the “normal” XP-E2 R4 between them.
Is XP-E2’s flux bins also about ~7% like the XM-L2,XP-L & XP-G2?
Basically the Jacobs clone (Jing ge A60) is a complete fail then?
Nah, that’s how the real A60 looks too
The Jacobs A60 i have don’t throw as bad & as ringy as that in the photo above.
Hmm mine was that bad with the original emitter. It’s a little better now, but still the ugliest beam i own
Mine are ugly but they throw
I’ve gotten my beam to clean up pretty well. No artifacts in the spill. It does have a nasty large corona though. Worst parts about this light are the lens (15+ percent loss OTF) and that it’s no longer available…
How did you clean up the beam?
Mine is as ringy as the rings of saturn 
it looks ridiculous on a white wall, of course out side where i would actually use it 
I don’t see it fortunately.
But i am not sure i like the very large corona with the XP-G2. But that could be because i haven’t got it perfectly focused yet.
I made the mistake to build it the same day, i built my UF-1504 with a fully DD without a driver just driven from the battery, dedomed XM-L2 U4 1C.
For the Jing Ge A60 i used a XP-G2 S4 2B dedomed, driven the same way.
And the UF-1504 is just SO much stronger with that perfectly square die spot intense solid looking beam, i really like it it looks great & easily the best thrower i have built yet :). And unfortunately my modded Jing Ge A60 pales in comparison.
The beam of the Jing Ge A60 with the XP-G2 S4 2B, looks to soft, it goes quite far, but i maybe haven’t gotten the focus right yet, because the spot is rather undefined & big at distance, for a XP-G2.
You confused me with this XP-E2 torch than I figured out that it may be new XP-E2 Led 
Yes. Same thing happened to me(lux jump) when I took 2 7135 chips off 3A Vinhnguyen54 pill I ordered years ago.
Check out djozz test (who else thanks djozz) on the XP-E2 Torch U5 flux bin. in post #81 
But we can’t buy them at our normal modding supply shops yet unfortunately, back then it was Mouser that had them.
Oh yes this XP-E2 torch should throw 220 kcd in Jacob even in case you picked up lowest performing one so it can be even better if little luck is involved. Djozz work is impressive equally as HKJ in batteries section. His threads needs to be merged in one as HKJ did on his web page.
I got my A60 with the de-domed XP-E2 R3 1D0 working. Put in a 20mm DD driver I had laying around - could be too much current, but I'm only seeing 150 kcd. I measured 2.79A tail. I'm using the translucent centering piece - tried loosening the bezel for focusing, but made no difference. I cleaned up the lens - it came out pretty clear now - it was cloudy originally. I didn't do any spring bypass's, using 24 AWG LED wires, and tried it with a Pana B cell to be sure I'm not further reducing resistance. May have to go with a 7135 driver, and try to pull the LED out further from the reflector.
The tint is the best I've seen on a de-domed LED though - looks like a XM-L2 3C or even 4C tint, really nice, no yellow, pure white hot spot, no yellow corona. The beam looks well focused, but I know that can be deceiving.
I have lots of these A60’s and if you are using the XP-G2 you need to get that emitter way up in the reflector, the only real way to do this is to grind off the entire bottom shelf at the base of the reflector, a little at a time once it is opened up and then play with centering.
I have one modded by 18sixfifty, De-Domed XP-G2 on Noctigon running Direct drive, control the amperage by what battery you use and it is great.

Ok, that is some good info thanks Muto
I suspected i was way to far from the reflector to get a proper focus, the trouble is i have used fat 18awg wires, but the take to much room. And used a 20mm mcpcb pressfitted in.
I might change to a little thinner wires or place some tabs on the mcpcb to get the wires off the bottom of the reflector.
Beam will look perfectly focused at almost every emitter distance from reflector (wider or narrow hotspot which will give lower/higher lux numbers) but to my eyes(sun glasses helped me here) it was the brightest when I centered it about 1.8m from table to white wall ceiling to very tight hotspot(around 4cm hotspot diameter on that distance, like OK hand sign). And reflector got to be perfectly centered around emiter(you can do that only by looking hotspot at ceiling) because light can escape from hotspot and lux drop will happen.
Edit: XP-E2 as emitter used.
And I think you guys should use 22 high strand noodle awg wire in this mod. 18AWG is to thick and it will disturb in centering reflector from emitter.
So, now that A60 is out of stock, whats the alternative, which is as good or even better, is there anything under 20$ that can beat A60?
The Cofly A60 at AliExpress for $15 now is in the running... Though a bunch were ordered off that site, haven't seen any feedback here on them.
So, would you all be interested in a better made light almost identical to the A60 if it were a little more expensive? yes I have something in the works. But it’s about twice as much as the cheapest A60’s but will be much better quality with an aluminum reflector.
Definately yes, at least me
- good reflector
- solid pill or base and suitable for A17/20DD driver
- solid and easy moddable tail switch
- 1 battery
If its only a host: even better
Up to 30$ is fine, and it would be a great thrower at a reasonable price……kind of a M2X UT clone
