For the last couple of years, my keychain flashlight of choice has been my Olight silver 120 lumen i3E EOS. I like that itâs one mode, and the silver (probably chrome) finish has been almost scratch free even though itâs been rubbing up against keys all the time Iâve owned it.
The UltraTac K18 has been my go to keychain/pocket clip edc for quite a while now. Ended up with 2 of them, because they are fantastic either with a AAA or a 10440.
Lovinâ my Nitecore TIP 2017 (i put a 219C in it).
Also love my Astrolux M01 (after fixing the flickering problem: replaced the e-switch thingy with a tiny piece of sheet metalâŠ) which is a true keychain light, itâs on my key ring.
I have a Wuben G337 on my keychain I got for ~$10. I donât use it that much, because I usually have a UT01, or a SP10b on me, too. But itâs there when/if I need it. Runtime and brightness are both impressive for something so tiny, and I can charge it from any micrUSB cord.
Iâm pretty sure it shares the same charging circuit and 2 level resistor ballasted âdriverâ as many of the other similar tiny lights.
I got a couple of these Glaree E03 150 lumen AAA lights a few months ago on amazon, they are $7, sometimes on sale for $5, 3 modes + a strobe, pretty good light for the price
