Dedomed XP-G2 S4 2B.
XP32 Noctigon MCPCB
2XR100 resistor mod.
719.640Cd (1.696m) at start.
709.200Cd (1.684m) at 30 seg.
Spot in low at 4m.
250m.
OMG! How in the world did you do that signature marking? Awesome!
No disrespect, but I find that 719Kcd difficult to believe. I’ve had mine (when I had one) at 500-600 and the spot is intense, even at just over 400 it threw across the Mississippi at Vicksburg. Probably deceptive though, as there is a lot of ambient light in that picture for sure. I know it’s very hard to reach those numbers, in ANY light.
I did the same thing with the 32mm Noctigon and XP-G2, found the driver very difficult to mod fully as it would peak over 8A and blow emitters at turn on, very frustrating for me to get the output limited just below ceiling. Finally traded it off.
Great work, love the writing, hoping you’ll share how you did that!
I used an electric engraver with carbide tip.
Thanks, gotta check into that. I’ve been using a very small carbide bit in my Proxxon that actually came from my Dentist! It’s prone to grab and bounce around as it’s 2 flutes.
Do you use the lowest or highest speed?
How do you go about laying it out on the light? Free hand it with a pencil first? Looks great!
What a beautiful color that C8 came out! Awesome!
And every “Fatman” is exactly the same! How? Enquiring minds want to know!
Yes. Free hand it with a pencil first.
Sorry to be so full of questions, but does that engraver vibrate the tip or spin it?
We used to have one of those, I put my Dad’s DL number on everything decades ago! Where oh where has our engraver gone?
The tip vibrates at 7200 rpm. I bought it in ALDI years ago.
The anodizing of Maxtoch is softer and easier to burn than Fenix one. The 2X logo is more like the lightpainted original.
That Convoy C8 came out gorgeous, made me want to do one, so this morning I stripped a new matte black Convoy C8 and cooked it. I saw it go a nice bronze maroon kind of color and stopped right there! It’s cooled down, I’m at the re-build it stage, but can’t decide what to do with it. Thinking about a green emitter, not sure. The green emitter I want does over 2000 lumens, has a 4.9Vf and costs over a hundred bucks!
What LED did you put in?
You have excellent skills Lfatman!! :face_with_monocle:
No doubt your pretty mean with a tattoo machine and with airbrushing… 
Hah! I remember those red plastic things. BZZZZZZZZ. You could adjust the intensity of the buzzing.lol!
Fenix TK75 2600lm:
- Fenix spects: 92.000Cd (606m.)
- My readings: 94.320Cd. at start and 92.520Cd.at 30 sec. (608m)
Olight M3XS UT Javelot:
- Olight spects: 250.000Cd (1,000m.).
- My Readings. 270,360 Cd at start and 252.000Cd. at 30 sec (1003M.)
As you can see, my readings are only very slightly above the ones offered by the manufacturer. If I’m making some imprecision, it must be very small. I have done several tests and the results are consistent. I can not think of another way to defend my results. Maybe I can upload a photo of long distance soon…
You are free to believe or not my results. I have no need or interest in lying in my statements.
If we dedicate ourselves to lie, this forum would lose its meaning and its raison d’etre.
Thank you for your comments.
V10R Ti with graphite battery tube.
Very nice 8)
Yesterday I had an appointment with Nico (member Nicolaas) to compare his new Extech luxmeter with my Mobilux luxmeter (that was interesting, the colour filters were quite different, with white leds the difference was not dramatic, but at 450nm his meter measures three times as much as mine).
We also spent some time modding his Courui from dedomed XM-L2 to dedomed XP-G2 S2 1D. Unfortunately the absence of a proper centering ring for XP-size made the focussing and centering so difficult that the throw went down instead of up.
In a brain wave Nico suggested to ditch the XP-G2 and put the XM-size 400nm 2.8A Epileds led in the light, that I did a quite succesful output test on a few days ago. It was risky because the Courui had a (6A) LD1 driver, while the led output is maximum at under 5A. With some not so high-drain batteries it should work, and it did.So now his Courui throws several Watt’s of purple radiation in a tight beam to a place far far away, quite impressive! 
Ok, that is by far the most badass looking flashlight I have ever seen. ::DROOL::
Agree, it looks great! 
So how does one obtain a graphite tube? :question:
