94mm ID, just a bit bigger than the TN42.
I will probably get enhanced aluminum or rhodium from Phoenix Electroforms.
Pretty sure gold isn’t good for visible spectrum.
You guessed it 
Also the only thing better than the stock reflector would be an electroformed one, not some cheap aluminum chinese reflector.
What does that mean? O.o
In case you didn’t notice:
Yeah just saw, that’s awesome.
The better efficiency should give even more lumens at 12 amps, and more throw too since the dies are all together 
Will probably be a few months before good bins are available.
I plan to make the hellfighter easily upgradeable, with two screws holding down the LED, so you can just take out the reflector, unscrew the MCPCB, unscrew two wires and swap out to a new LED.
Right, I might hesitate to mix a top end Surefire light with Chinese non electronic parts as well…
Now THIS is good news!
Wait throw? :person_facepalming: 70.2 No way! The xp-g3 nope, the L.2 nada, the 50.2 is a joke! High Out put, High Heat and No-throw! 
Try de-doming any of the above!!!
And all three look like crap out of a smooth reflector, the 70.2 will be the same no hole but golden bung hole around the hot spot!!!
Not dedomed they make more lumens.
Obviously I wouldn’t try dedoming a .2 we all know how bad that turns out.
The point is to get higher efficiency and more lumens, while maintaining the same throw or better.
Having more lumens output from the same area increases throw, so compared to a domed XHP70 it should use less power and output more lumens for more throw.
Also with the dies closer to the reflector center of focus the throw will increase as well.
Also, I have XP-G3s and I think they look fine.
With a cool colour temperature there is no gold, it’s just more neutral white.
Take a look at some xp-g3 beamshots, it’s not bad at all.
My cool white XHP50.2 in a SMO reflector looks good to me, too. No complaints.
Yup. It seems pretty exaggerated to me, Although maybe it’s a lot worse for 3000k-4000k LEDs?
Idk, all of mine are 5000-6500k for highest lumen output, and I would do the same for the XHP70.2
Yeah, the L2 I built with the 50.2 J4-1A couldn’t even compete in throw to the shaved old J4-1A in my other L2’s , go ahead and shave that 50.2 and see what happens, I’m sure you will still say you love it!!! :person_facepalming:
So me and the TN42 XHP70 P2-1C De-domed will lose sleep, 
because I’m not getting that up to 9% more output and all that efficiency, over the new 70.2, :cry: but LOVING all that Killer De-domed P2-1C Big Beam throw! :heart_eyes: I’ll keep kidding my self, but in the meantime, all you little more out put, (up to 9%) and higher efficiency fan boys send all your old High Bin XHP35/50/70 Quad die emitters to me, hurry cause they are going to mess up the XHP35 next!!!
:laughing: LMAOff!
You can’t shave or dedome the .2 emitters because they contain phosphor in the dome, it is not a flat die.
What I want is the highest lumen output from a non-cob LED.
I already have a thrower that can do over 2.5km so this is more of a regular use flashlight to light up large areas, so throw is second to lumens and efficiency.
The XHP35 is a flat die emitter like the HI leds, so they can’t really mess that one up because it’s specifically meant to be flat.
Anyway, it just seems like you have nothing else to contribute other than complaints and facepalms, so please go away and do something more useful.
Whoa.
Hahaa just shaking the bush boss and thanks for the advice, I will! Great angle though, a Highly efficient flashlight!
No exaggeration, how about an expert’s observation….
The 70.2 will be the same…….
Thanks for the link. I also got a 3000K XHP50.2, but I still have to reflow it to a board. Last month I had little time, so I still have to make some more testing. I will post my results here or in the XHP50.2 thread.
As soon as the XHP70.2 will be released, I will definitely get it and see how it performs.
I took a bunch of beamshots this summer, because I wanted to use the light at least once before I converted it to LED.
The antenna is 1000m away:
Path in the woods:
300m distance:
.
.
.
On a different day I also went on a night hike with a bunch of people, and the hellfighter lit up the path for me and the other 20 people in front 
It became more of a “day hike” than a “night hike” with this flashlight!
Some large open fields about 100m+ square were easily lit up by the 3500 lumens.
The light does emit a high pitched coil whine when on, just barely audible. This should go away when converted to LED
I used two of the 6Ah Lipos and used two thirds of their capacity during the 2 hour hike. With a full battery pack with 4 of the LiPOs I would have about 6 hours of runtime.
dang, impressive!
yeah those short arc throwers are beasts, just not too practical like LEDs
It’s not short-arc, just a “normal” car HID.
Also 6 hours of runtime without any dimming sounds pretty nice to me :+1:
Thanks
When I convert it to LED it should have about 2x the lumens and more throw too, since the XHP70 is very close in diameter to the 4mm arc.
Wheat’s interesting is that the Hellfighter doesn’t have the arc exactly centered at the focal point, it is slightly forward.
This causes it to have two “hotspots”, one that is large and then one small point in the middle (where it overlaps) to give the highest intensity.
This gives a larger usable spot up close while still having far throw in the center.
