The one i used most, almost daily are my keychain lights.
I have a 47’s Atom triple XP-L HI with momentary magnetic tailswitch that can be operated with the light attached or detached to the keyring holder which i made from a flashlight strike bezel. The light can also be used as a normal twisty.
LD3 driver with temp control, two tritium vials in tail and one on top of the holder. Graphite aesthetics.
Also on this keyring is a DQG Hobi Plus with 365nm UV emitter, ZWB2 glass and the DQG lighter in the top section.
Thanks for the giveaway :+1:
