Welcome back. My EDC flashlights are key chain carried. Main light is a Fenix EO5 with a lithium battery. Back-up ( two is one, etc...) is a Photon Freedom with a yellow LED, carried backwards in its neck dangler, to prevent accidental “on”. This combo has been my “ go to” for many years in a highly urban environment.

Like you, I also keep handy, an Infinity Light, albeit a later Gerber version. I use mine i at home, at night, when I don’t want to light up the room or for various in-home chores. With a lithium battery, it lasts for 6+ months of daily intermittent use, at a minimum. NB: if you ball-up a bit of aluminum foil as a filler, the Infinity will run on a AAA battery.
