You sure you want a small light like that? Lightweight, sure, but harder to grip and fiddle with the switch.
I’d suggest an Ultrafire DV-S9.
Sure, it’s big, takes a 26650, but includes a sleeve to use an 18650, which would lighten the heft of the light.
It’s got a magnetic slider, just like a wall-mounted dimmer-switch, so it goes from off to full-tilt and everything in-between. Nothing to “figure out”.
Parasitic drain is only 10mA, so should last a while before needing a recharge. Use a protected cell like a panny-B just in case. Lights like an UF F13 and even the cheap-as-crap (and I mean that in the most literal sense) UF AT-01 include adapters for 3×AAA, too. Might want to get one of those adapters…
I just gave mum an AT-01 with the 3×AAA adapter, because I don’t trust her with any Li cells, even protected. And yeah, sometimes I see her strobing away ’til she figures out she’s gotta bap the switch again. :person_facepalming:
But, at least it replaces the army of garbage-lights she collected over the years, all those 9-LED tubes and showerhead lights. They all just flicker away at this point, yet she refuses to dump them.
Only 16bux or so at FT (sale?). See if the BLF discount works in conjunction with the price-drop. Think I’m gonna order another one anyway.
As far as the AT-01, if you’re willing to do one quick solder-blob, you can bypass the 3-pin controller IC on the driver board and make it a 1-mode light. This way you got a zoomie that has a decent flood which they can just leave as-is and just use the tailswitch.
If not, then I’d $ugge$t a 2×AA MiniMag with LED upgrade (eg, 1W Nite-Ize drop-in). Simple twisty on/off, decent flooder, not painfully bright, eats plain ol’ AAs, lasts a lifetime… not just their lifetime but probably yours and your kids’, too. Bulletproof.
