runtime on countrycomm $1 keychain LEDs

[Datasaurusrex]

Hey, does anybody know the approx. runtime on those $1 keychain LED lights that countrycomm sells?

I'm asking about total non-stop runtime... not intermitant use.

Thanks

If they're like similar 2x2016 white led lights, about 1 hour pretty bright, then 3-4 hours medium, then 10+ hours pooped. They will run a lot longer on 1x2032 but won't be as bright.
