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.
Received my GT Micro today, and it’s very nice - feels more compact than an Emisar D1, even if it’s not really smaller. However, the engraved name on the battery tube is on the reverse side to what I’ve seen in other pictures. It’s not possible to just untwist the tube by half a turn as this disconnects the battery. Anyone else have this happen?
As I was looking into this though, I had the same issue as at least one other person here: Re-assembling the light it turned on by itself at full power, the switch did nothing. There was a quick fix posted, but I don’t remember precisely what it was. I have no tools (not even a good soldering iron) to allow me to do more than clean a few connections.
The battery tube writing can be anywhere. It is completely random. If it bothers you, you could sand down the battery tube end to make it shorter and that will allow it to rotate more.
Getting full power when connecting the battery could be due to a short circuit. I’m not sure. TheAuditor said he cleaned the contacts on the driver and battery tube and it fixed it, but not really. The problem came back. Neal is sending him a replacement head.
A high powered light does not make a good gift to a muggle (i.e. non-techy type). Not sure those will fit, but if they did they should work ok, but you just won't get as much power. The good thing is less amps are drawn, therefore the battery lasts longer. I didn't check parasitic drain but I'd be concerned about that for low capacity cells. A Q8 with 4 18650's can last months and months, years even, sitting around without charging, but a light with a switch LED and a 14500 under 1000 mAh -- it's a risk, not dangerous (I don't think) but a risk to kill the cell.
Yea I know but he seems to enjoy my small throwers every time he comes over to visit. And I figured the micro would be a good fit. Just wasn’t sure about the battery choice
I got 140 microamps parasitic drain with the switch light on.
Got my Micro today and I love it!
Mine was just delivered today as well… where I work, and I’m home today. 
I tried to open it annnd…
A drop or two of blue Loctite, nothing too hard to break open with bare hands
40kCd with a trustfire 14500 @ 3,2A only… might have to invest in some good batteries.
Now, the real good news is : the LED shelf is insulated from the negative side of the battery. This means this light is usable with a Black Flat !
EDIT :
It is a perfect Black Flat host guys !
I reflowed one on the stock copper MCPCB, and simply removed the centering ring to allow the reflector to sit directly on the MCPCB.
3,2A and 105kCd @ 10m !
Niiiice! How is it that the emitter shelf is isolated, by the anodizing?
