The reflector is sitting on the mcpcb, (no centering ring) which is white, I did run a black Sharpie over it. :+1: The Doberman came with out a centering ring, the reflector has 2 outer support rings that are relatively tight to the head’s inner diameter, so centering is tight, just the reflector to me isn’t right to focus even on domed LED’s let alone dome-less LED’s. But the W6 is putting out some pretty impressive lemons, and it’s fair to midland when using it outside, so I’m done wasting time on it. 
But thanks anyway’s!
What gasket did you use for the l2 and what did you do for focus?
Removed gasket. Just one layer of kapton tape around led to not scratch MCPCB with reflector. Reflector sitting on that. Wires soldered insane flat. Reflector bottom sides grinded a bit to clear wires.
Oke and centering just twisting the bezel?
Yes but it needed to put some tape one side of the head inside to push the reflector sideways.
I asked Simon from the convoy store if he could get some gaskets made for 9mm reflector hole and he said could.
(1mm² led)
What should be the inner diameter of the hole inside the gasket?
Which reflector is this for? We really need some centering rings for the Osram Flat Whites to fit the L2, C8 and S2’s. Hoop is supposed to be making them but haven’t heard anything in a month or 2. Not sure about the L2 either.
The gasket from int outdoor is for 7mm reflector.(convoy s2+ etc)
The c8 and i believe the L2 use a 9mm reflector hole.
I bought a solid tube of pom plastic and will try to make some gaskets myself. If it works out I will report here.
I talked about WF1 with Simon a week ago and he told me he will get some testing samples after chinese new year and maybe consider putting them in C8. I will help him in every way I can after my 6-7 WF1 builds conclusion and led measurements.
Sweet! Thanks. Can you communicate the dimensions of the gasket with him?
I told him to just ask me if he need any measuring. I will do it.
I would be interested in 10 or more of those centering rings. Looks like I have a few people who want me to build pocket throwers for them.
I ordered some POM plastic to make myself some gaskets. All hand work and no fancy tool avaible. Its a little to loose in the reflector but I will make some more later.

Geez, this is dedication
And a lot of skill. Nice work. 
Got some good news for anyone wanting to swap the 1mm2 emitter into an MF-04. The stock isolation ring does actually focus the emitter quite well in this light. I finally got back to this light last night. I centered the emitter (trial and error when tightening the bezel. Once I got it centered, I was able to confirm focus. Atmospheric conditions are very bad right now due to extremely high pollen from pine trees. I will measure throw and get some beam shots after conditions improve. The beam is beautiful and clearly beats my BLF GT which I measured at about 1 million cd.
Has this stuff been tint and CRI tested? I understand these are no high CRI emitters, but the information still matters. 
I can’t remember all of the correct reflector opening diameters, but this new listing from Richard might be of interest:
OSRAM Flat White Adapter / Spacer Ring
Anybody try one yet? He also has 1mm WF’s listed.
The tint is probably good, the older black flat was more reddish than greenish at high currents. The cri is obviously low (the only way to get max luminance), it should be stated in the datasheet. Probably around 65-70.
The xml smo c8 reflector is 7mm but all the c8’s with xpl hi came with larger 9mm holes. Im not sure about the L2…
