I’ve tried to open thing up and I can’t do it. My trusty needle nose pliers fit in the notches just fine, but the notches in the retaining ring are rounded, so the pliers slip out.

When I do manage to get them to stay in place and apply some torque, it damages the brass ring, the edges of the notches are even more rounded off now and it’s futile to even keep trying.

I did get my old one open using the same method, and there wasn’t any visible glue on the threads. Just put together super tight.

I’m curious what you use to get that retaining ring out.

Either the newer ones are harder to open, or just this particular one.

It works as is, but having a light I can’t open irritates me to no end.

Would it be possible to use a Dremel tool and make new holes 90 degrees away from damaged area in brass ring?
If so, then use 2 strong nails/drillblanks/etc. set in a vise at the proper distance and set the head of the flashlight down onto the nails and turn the head with big lock jaw pliers. Maybe with rubber gloves/intertube as a protector from damage.

Just a thought.

EDIT;
I do have one off these, series one, forgot it was on hand and I now see just how small those cuts are in the brass ring. No real room to drill holes.
Bad design from a modding and or service standpoint.
Still could try new cuts and maybe one of those ring pliers that expand when squeezed.

Yea. Not a lot of room to work with, and great risk of destroying the driver in the process. They aren’t made to be modded or serviced I guess, just built once for cheap and thrown away if they stop working, just like most electronics these days. On the other hand, I also have the Thorfire TG06s which is super easy to open up and mess with. It’s a much better AA sized light for modding.
