Following on from a similar topic...
I see many lights marketed as EDC or designed for EDC. Certainly I'd not carry half of them every day, but of course my needs differ from everyone else's.
With such a wide variance in size, features, cells, performance and so on, it got me wondering if there's a general standard for such things...
So, rather than a tactical one, or one for hunting, or Duty, or inspection... What would you (in your personal view) say defines an EDC light?
What defines an EDC light is that you carry it every day. That what EDC means: every day carry. It's the act that defines the category, not the manufacturer's marketing or design decisions.
My EDC light is a 2021 Fenix E12 v2.0. Why? Because I long ago decided that the 1xAA format was right for me because of its particular combination of size, weight, and availability (particularly the weight and availability of Energizer L91 lithium iron disulfide primary cells), and the E12 has the type of operation mechanics I prefer: tail switch, always turns on in lowest mode, three modes only.
But my 2021 Fenix PD36 TAC could quite easily be my EDC flashlight if I felt like carrying a larger and heavier light. Fenix markets this as a "tactical" light, and it actually does meet my definition of a true "tactical" light, but it also cleverly incorporates just enough additional features to make it usable as an EDC light without compromising its tactical usability. The only thing the PD36 TAC doesn't do is offer a 5 lumen mode; its lowest mode is 30 lumens, which I regard as too bright for most of the reasons why I carry a flashlight every day, in the first place. But, that 30 lumen mode is fine in many other circumstances.
My regular EDC items are all tiny:
Victorinox Rambler knife (my most-used knife)
Fenix E12 v2.0 light (with extra AA battery)
Fisher Buller Space Pen (all-weather emergency backup for my fountain pens)
Bic mini Bic lighter (most convenient fire starter)
and a few other items of similar size, in a tiny zipper pouch in my handbag
Now, I almost always also carry a larger knife, a Gerber Harsey AirFrame, but I don't feel the need to carry the PD36 TAC on a regular basis. Mostly, it's my bicycle headlamp.
The two other lights I would consider for EDC are a 1x16340/CR123A (Fenix E18R) or a 2xAA (Fenix E20 v2.0). Anything larger/heavier is something that won't "go everywhere" for me, which has to include fitting in a tiny formal evening clutch or wristlet.
