Flashlight Modding and DIY Parts

Am I missing something? I cannot seem to find a host like this. Not sure I have even seen a commercial product that might not be glued up tight. Any suggestions?

No side switch, but the S12?

Up to you to decide what moddable means but here’s some ideas cant vouch for any of them though.

FireFlies E01

MATEMINCO TK01 (and whatever astrolux is called)

WainLight copper?

I am looking for a true tube light, something like the Shadow JM20 or the BLF Trustfire A8.

I am thinking that will be about as close as I can get. The JM20 also has a tail switch for on and off, but that may not be an option nowdays. I had not see the JKK.

So, has anyone done a tear down on the JKK21700? Is the switch part of the driver or independent, is the USB board integrated into the driver or independent?

This is basically the same light as the Wainlight copper, but in straight alum. 8 biz days from BG means not in stock, and who knows if they still make them. It has that snap-on "BD" style charging, probably a 7135 based driver, and probably the UI has the press&hold for ON and OFF, based on the copper version review. Fasttech has them too.
