I just wrote my introduction, said I probably wouldn't post, yet here I am already... because...
I'm not a flashlight enthusiast (yet? I think?), but I do keep a small flashlight in any bag that I regularly carry, (and am looking to replace two ancient incandescent minis myself -I love this forum), and have been giving a lot of thought to the form and function of minis lately. Perhaps the question ought to be, what do you expect the recipients will do with the lights? If you're taking them camping, well, everyone's choice is more informed than mine - you can ignore the rest of this.
A non-enthusiast's mini might go in a bag, drawer or glove compartment and get used once in a while. If you hope it will be an EDC for a commoner like me, you might consider something like the Fenix UC01. I have been carrying something very similar on my keychain for years (same one, over a decade old). It's never in the way. It's on in my hand (with the car keys) in dark parking lots on the way to my car for safety. It's great when my porch light goes out, or I need to dig a real flashlight out of _ _ _ , or the kids have been playing with my car interior light settings...
Maybe a keychain light doesn't make a very bold impression as a gift, but if somebody adopts a safety habit because you made it easy to do, maybe they'll thank you more as time goes by. Just my thoughts. Now if you'll excuse me, I have to go buy that UC01 for my daughter. Cheers!
