can be put into S2 S3 S4 S5 S6 S7 S8, M1 M2, C8, L4 type flashlight .
You have to use glue to fix it ,for example ,ergo7200 glue
Notice that once you glue it in your flashlight tail ,you can not get it out anymore,and you can not use the lanyard hole.
Nice option, it fits the BLF EE X6 as well !!
Looks pretty strong 
Is it a neodymium magnet?
I knew that Simon would come through for us.
Nice Simon. You were quick getting those magnets.
Axial? 
or ‘diametrically’ (across the diameter) 
Are you sure of that? If so, I’d be likely to get one for mine. I don’t like how the X6-SE is unstable in tail-standing and this might help with that.
Awesome!
YES ,FRIEND
Axial
Nice, it looks like you found a cheaper source than me !
Honestly, you got the idea from my submission in the 16340/18350 S2+ post ?
thank you ,ordered , i hope you find as source for the 18350 S2+ battery tube as well.
It looks like it renders the lanyard hole useless on a Convoy c8 :~
Yes, the holes are blocked to lanyards or pocket clips on most of the Convoy models
Which sane person uses lanyards anyway? 
I will order one set of them. I already have “pimped” some smaller lights with magnets, but also the BLF SD10.
I haven’t used it till now, but it’s nice to have. Like having 50+ flashlights…
