If you want to avoid the AA batteries, you could spend a little more and get the Sofirn SP40. I've got one which I rely on pretty heavily and it has served me well this far.
The solution is always more. I ordered a Klarus RS10 for my Dad last week. He's been a lifelong 6V Dolphin user since the 70's.
He can't remember where the AAA Fenix I gave him a couple of years ago is. He pulled his Dolphin Mk6 out of the cupboard a couple of weekends ago for something and I was embarrassed for him when he turned it on.
I can't let him live like that, what sort of son am I?
I'm really happy with my little Wurkkos fc11. Goes from quite faint to very bright, 18650 battery, usb-c port for charging, easy to use, IPX7 water protection, magnetic tailcap so you can easily attach it to all sorts of stuff. And at only ~€28 it's quite cheap.
The 2700k temp option is also very nice for a more cozy and not so harsh light.
Two questions, do you have the 519a version and if so how is it? My friend wants a decent light but doesn't wanna jump down the rabbit hole and it seems a good option for him. Secondly, have you tried removing the tailcap magnet? He doesn't want one but I read it can be removed.
Pretty much the only light I take camping anymore is my Lumintop Tool 2.0. It runs off of a single AA for quite a while (although I have a 14500 in it at the mo) and quite bright enough for anything you need it for around camp, easily carried, and unlikely to permanently blind or set anyone on fire.
I love my Zebralight w51: Doubles as a headlamp, uses a single AA, and can run for 40 hours on the lowest setting. I use it both at work and while camping (along with a Fenix TK19)
I’ve had good results with cheap gadget flashlights. Small is good, so little fingers are willing to carry, cheap is good so I don’t mind when little fingers leave them somewhere, and low powered is good so little fingers aren’t constantly blinding people.
Our local hardware store had this one that just worked:$4.99 before pandemic (so $20 plus tip now?). It was rectangular not much bigger than the three aaa’s that powered it. Small edge projected a beam, big edge lighted an area, back had magnets and hook. They never lasted very long but fit nicely in a pocket and covered all needs.
We have mosquito lanterns for when we go camping. Pretty neat. Goes on AA batteries and drives the 'squitoes away. Costs like $30 add a couple of handhelds from the hardware store for nightly toilet business and you're set.
Olight Obulb looks good for kids. Max 55 lumens and sustains close to that for 3 hours (review), waterproof and with a kid-friendly appearance. $20 on amazon currently.
These don’t provide much illumination but the Niteize rechargeable glow sticks are good kid lights too.
