I just got mine in and it looks pretty good and it works 
If i cut of the rim of the pill how do i screw it back in the flashlight?
I did all in this exact order:
-insert the driver in the pill and fix it with the retaining ring
-apply thermal paste on the (flat) top of the pill
-screw the pill in the head from above so that the flat top is 1mm above the flat bit inside the head surrounding it
-screw the battery tube in the head, against the pill, screw very tight, which is both fixing the tube and the pil in position
-position the ledboard on top of the pill
-solder the ledwires to the ledboard
-add centering piece, reflector and glass, close the bezel
-hope for perfect focus and centering 
Thanks for your reply djozz! Im also from amsterdam 
You didnt take of the rim? At this point i want a big mcpcb like 25 mm with a xpl hi on it and put it on the pill without rim. What kind of mcpcb did you use?
maxtoch 26mm or manker 28mm
the manker one is easier to find
I did remove the rim, as described in post #446 above, but did not mention it because the question was about screwing the pil back in. And I used the 26mm board.
I live in the “Indische buurt” btw, in Amsterdam it never gets dark enough to need a flashlight

This is how my best Mitko’s thrower looks like(over 320kcd) :
@djozz oke i will try and remove the rim… did you get a 26mm board with led on it? Maybe i need to reflow one myself. This will be a challenge lol
Well, finally I got the flashlight, put a xml2 noctigon 20 mm, dedomed, and driver blf a6, only gave 156,000 cd to 7 meters, with lg h2 …… I expected a little more …, greetings!
, Had not done bypass in the tail and improve a little the adjustment of the center, now more than 198,000 CD, not bad, I think …
They have this light on sale right now at AE for $15.67 for the next 2 hrs it says on site, SupwildFire CREE XM-L2 U3
I just modded mine. I went with xpl hi on 26mm maxtoarch board. I put a thin gasket type spacer between the reflector and the mcpcb. The hot spot is still pretty big. Bigger then c8 with xpl hi. What can i do to make the hotspot smaller?
I just tried my hand at one of these today. The host itself seems kinda “meh” but it did seem to have an actual XM-L2 in it and a beefy Omten switch.
My approach was something similar to what L.I. tried: stacking mcpcbs and opening up the reflector to accommodate them. But instead of using two 16mm boards, I stacked a 10mm onto a 16mm and soldered them together. LED is a dedomed newer XP-G2 S4 2B. Driver is a BLF A6 FET+1.
I really need to take it outside and try it. Inside the house it appears slightly tighter than a XP-L HI C8, but certainly not awe inspiring. I might have to fiddle with it some more.
I’m not so sure the 10mm board was a good idea. The lead wires slightly affect the beam.
Lastly, I don’t recommend using a pencil torch such as this for reflowing by applying flame directly under the mcpcb. That solder paste flowed in about 1 second and quickly cooked the top board to boot. Oops.
Nice idea. But I think it protrudes to much into reflector which may result in wider beam. So try to lift reflector a bit by putting tight and larger diameter o ring under reflector upper base or lip.
If you think it is good centered make “1 meter white wall recheck test”. For best lux performance beam should not have donat hole in the middle of the beam at that distance. Since I learned that on mine mistakes Now every Mitko’s thrower go well over 320-340kcd with good old g2s42b.
The led should be further away? I used a spacer that is like 0.5 mm and te beam is pretty wide. Should i put a spacer in there that is like 1 mm? Or remove a part of the reflector…
@djozz i got a crappy wide beam. If i dont use a spacer between reflector and mcpcb the beam is still to wide for what i think it should be. Do you know what i can do? I used an 26mm mcpcb with xpl hi.
15.77$ on ebay
@polarweiss, I don’t know what is different in your build, are you sure that the reflector is not prevented to get close enough to the board by some obstruction? And that the led is centered precise enough?
At least in my two builds (Black Flat and dedomed XP-G2), the reflector at less than 0.5mm to the board gave a well focused led.
Finally I received this light to play with (first order got lost). I haven’t made much pictures of the build only the two below.
I sanded down the pill rim and in the center of the pil I added a sanded down noctigon. On top I placed the maxtoch mcpcb with dd xml2 u4. All glued together with artic silver adhesive.
Took a while to get the focus right, but it has a real nice useful beam now.
Didn’t like the shiny ano, so baked the light on the stove.
That is a nice solution Geuzz! (and a good colour too)
Very nice and light light. It encourages people to step forward into modding art and it is probably best reflector thrower in this reflector size(diameter, depth, single 18650) in a world.
Thnx! It’s a really nice beginners mod light. Does not cost much and very rewarding in the end.
