It’ll glow for years regardless of how much light you feed it.
It’s a GITD marker that lets you find your thing in the dark. It’s also used for markers on watch dials and gun sights. But in at least those tiny sizes, it’s not a flashlight substitute or anything like that. You could add a flashlight to your keys, so the tritium helps you find the key ring and then the flashlight gives you more light if you need it.
I feel like most EDC stuff is underwhelming, but I still enjoy it tho
It all depends on when you get a reason to use your edc. For example i edc a condom and i swear if i ever get to use it i won’t be underwhelmed
I dunno, I kind of like it, kinda neat to show the power of the atom to have a light source that lasts a decade or so before slowly fading.
