Looks like the results of solder flux splatter to me, sometimes the stuff spits and it lands on the emitter, it’s usually clear and not readily noticeable. An alcohol dipped q-tip might clean it off, but now that it’s burned on it might not clean up so easily. A simple emitter replacement will solve the problem in a worst case scenario. Two wires…
I use a micro fiber cloth with isop. alcohol to wipe down the LED's and MCPCB as a final cleanup. I haven't been able to open the bezel so far on the Micro. Not sure if it's just tight or glued. Haven't tried the more significant methods of clamping/strap wrenches, etc.
Has anyone been able to open it up yet?
Not yet… Trying to resist the temptation to do so, as it works great as-is. But so far, I’m 3 for 3 with GT, GT70, and Mini…
Received my CW micro today. It’s so tiny!
Did anybody else notice a yellow spot right in the center of the beam?
The delay from Neal kinda spoils all the fun, I meant to have one of the first White Flat GT Micro lights but of course, that’s a big no as I don’t have the lights I paid for yet. And no word on what’s going to happen…
Yea, this roll out could have gone better... I should have time this eve to spend on trying to get the bezel off.
Funny though - the EDC05C and this came out bout the same time from Lumintop, both 14500's but very different lights. The Micro at least supports flat top cells, the EDC05C doesn't, but for production, they will ship the light with a compatible cell (hoping... 
).
Hey, mine’s finally in LACA (lah-cah), so I should be getting it… soon.
Got the bezel off and I got those glue blues... Blue Loctite. Needed it to be well clamped between wood in a vise and good pressure from a strap wrench.
I got pics but Photobucket got those spin'n blues - loading forever... Tried Imgur but no luck so far.
Ohh - does this work? This is my setup. This shows the light tightly clamped in pine boards, maybe the angle helped, dunno, but it was pretty tight in there.
Here you can see I got movement - it was a slow steady process. It didn't simply crack the glue and came off easy, was stiff unthreading:
Cleaned up - used tweezers in the threads to loosen, also a hat pin, finger nail to remove stuff, and isop. alcohol in a paper towel:
It's down right dirty down there. Sloppy stuff, looks like a 15 mm MCPCB:
There's liquid or goo on the side. What a mess! No wonder some are having issues:
The tweezers I used. Didn't clean the bezel cap threads yet.
Slight raised surface ring:
Somewhat unusual, there was only 1 o-ring under the glass - nothing below the threads, like you usually find. Looks like there was a space for one though, but for a very thin one maybe.
My Lumintop ODF30 also had like 10 drops of blue threadlocker. One drop should be enough! 
Maybe all that glue does double duty making it water tight?
ODF30:
Did the mcpcb have an adhesive or non-adhesive compound under it?
I wonder why it’s so messy? I can understand a little flux around the wires, but it’s all over the place.
No wonder they want glue all over… Agree, just one drop is more than enough for such fine threads…
It looks like flux - cleaned up easy with isop. alcohol. They use a thermal grease under the MCPCB, looks white. It's a definite 15 mm MCPCB. I'm looking to install a white flat 1*1, bought a few from Hank.
It looks as if a 16mm MCPCB may fit? I had thought of doing the same thing as well, as I did with my Mini…
Flashlight glued… Order cancelled.
Thanks for the info.
Edit: Today I received a Mini, bought on February 23 in BG (with a free short tube). Un-glued.
Well I didn't pull it but I used 2 different objects and then measured - looks pretty definite at 15. You could trim down a 16 but need to take care of the pad edges - I've beveled them so no contact with the sides, but then the wire soldering can get tricky.
That lil rascal has a really neat reflector! 
Thanks for showing us Tom, appreciate it. Hope I see mine some day. 
Tom E i dont think that golisi 26650 gonna fit the micro
Neal is sending me a replacement head, so the long wait begins again 
I tried though
Jason - that Loctite I'm sure does help with the water proofing, specially since this light seems to lack an o-ring on the bottom of the threads. But like has been mentioned before, the Loctite could be used to prevent the user from causing damage, prevent contamination from user access, lock in the focusing, etc. Whenever you crack open that bezel, you run the risk of something falling down in the reflector, or on the LED surface.
Blue Loctite is the milder one - intended to be removed by tools, red is the more evil one.
JB Weld is the one that you have to machine off and make new parts…

Would this be a good battery for the micro? I am giving a Micro as a gift so I prefer a protected cell. I don’t want to worry about explaining the whole “dangers” of unprotected cells to the receiver of the gift.
