Thanks for this, keeping an eye on anything courui at the moment - if mine ever gets shipped, 4 days later they are asking me for a few more days!
nice mod thank you for sharing , any chance of Beamshots ?
Thanks for the comments 
@ Pulsar13; The Omten switch is actually pretty good, djozz did a good job of trying to fry one recently in his switch testing.
@ JaredM; I’ll try to get some comparative beamshots up, but my camera is lacking the manual settings to do it well.
@ M4D M4X; Just for you, I took a reading without the battery tube & switch assy; Jumping a 25r through the multimeter showed a little over 4.5a. Obviously the meter eats up a little current, but it’s all I have to measure it.
I will not be far behind you on this…haha. A new frontier for me
A wise decision bro! Modding flashlights is a gratifying experience. And the good thing about being in BLF is that the people here are always willing to share what they know. 
Very, very sweet! 
Congrats.
I have noticed this willingness to share and the gratification posts by our generous members here since I joined BLF. Right on, bro.
Updated OP with beamshots. Sorry about the short range.
That much throw for such a relatively small amount of total expense? It’s crazy, I would say.
Very nice pics, btw.
very nice work FmC
what numbers do you get @ 10 m?
Very nice. I particularly like the tail switch.
340kcd
Somewhat short of 1 million, I’m afraid to say 
Stick a UCLp AR lens in there and watch how high that throw number jumps.
My dedomed XM-L2 is making 369.25Kcd.
Nice work on that tail switch, not sure all three points were necessary at under 5A, but you gave it the whole 9 yds at any rate. Makes me want to add a switch to my XM-L2 version. It’s currently sitting awaiting use with the battery tube screwed out to break connection. Would be nice to not have to do that!
nice work
Congratulations! Very good work thanks for sharing
The switch in the tail cap is a brilliant idea, one of those that makes you say “Hmmm, why didn’t I think of that?”
Took about an hour to do what with getting everything out and putting everything away, and it’s just perfect! Positive lockout to keep the e-switch from draining the cells. The e-switch still works as expected and this is the icing on the cake.
Really appreciate you sharing the idea and pics.
Nice mod and wonderful to see such a writeup. Thank you very much :-)
Very nice mod FmC!
I thought I am the only one getting this “moonlight mode” when it is off, so is it really normal? I did the same thing like you by bridging the sense resistor and I couldn’t get rid of this annoying “moonlight mode” when it is supposed to be completely off! I reflowed the LED a few times (wasted a few drops of my AS5 as well 
) and even have changed it into a new XM-L2 just hoping to solve this issue but I still failed. It could be my soldering skill is poor but I have inspected every connection as carefully as I could but I didn’t notice anything strange though.
I see it as an issue… I even have created a thread here looking for opinions. Does anyone else have this issue? I couldn’t find other people experiencing this yet.
Best mod I can think of for the Corui, and very smooth work on the tail switch, well thought out! And you would think that the 32mm Noctigon should be wide enough to provide clearance for any reflector, but no.., LOL
bibihang, if I remember correctly there was some talk about some drivers not liking the sense resistor completely bridged in that it messed with the PWM to the extent that it wouldn’t completely shut off, not recognizing the off level through the e-switch. There needs to be some resistance for the driver to recognize off.
