Closest I can think of is the Fenix E01. Single mode, but it takes AAA and puts out 13 lumens:
It also has a twisty on-off action, which may be a problem with small children, because twisting too far takes the head right off (thatās how you replace the cell), so the very small head becomes a choke hazard.
Iām personally not convinced, but Iām gong to mention it anyway. Nitecore LA10 CRI. Yes it is 85 lumens, but it is 100% diffused, so itās not going to blind you compared to a 10 lumen reflector light. Itās single AA and price is less than $20 with discount.
The older Quark 4Sevens AA-Tactical. The 1AA is my preference. Yes it has multiple modesā¦ BUT they are Totally programmable. let me explain a little.
Its essentially a TWO mode light, tighten the bezel for mode 1, loosen the bezel just a little for mode 2ā¦ with a simple tail cap click switch on or off. No mode cycles, no soft press anything, no hidden-mode anything. Its a simple ON/OFF interface once you select your mode.
How you program each of those modes is entirely up to youā¦. firefly, low, med, turbo, SOS, Disco. You can even program the same output to BOTH modes at the same time so tightening or loosening the bezel results in the same output. So essentially in your case you would end up with the ~.2 Lumen firefly mode, programmed to bothā¦. and just leave the bezel tightened all the way down.
Availability is going to be your problem though. I checked Ebay 1-2 months ago and they can be found there, but being discontinued its going to be hit and miss.
I was at walmart yesterday and they had a 1-AA Ray o vac, LED flashlight that I think might serve this purpose very well. It was ~$3, and had what looked like a 5mm LED behind some kind of optic lens. Surely couldnāt be much more than 10 Lumens. I have no idea how reliable or durable they are though, but at that price you could just buy 3-4 of them and stash them in the tent or RV.
Since my suggestion isnāt available anymore maybe someone knows of something similar???
I would suggest an XTAR H1, itās a AA or 14500 powered angle head light that was intended as a headlamp. The low is pretty good but it came with a red LED that I prefer to most moonlight modes. These came out 5 or 6 years ago and I donāt see any on ebay or amazon.
(Dorcy often has 20 percent off sales, watch for those; Iāve found they also have great customer support if thereās any problem buying from Dorcy direct ā the one time I dropped and broke an outdoor motion sensor light, they just sent me another one, I presume knowing they were a bit fragile)
Gerber still sells the Infinity Ultra. Itās single mode & has a 5mm Nichia. Essentially the same as the Fenix EO1 except using a AA. They were popular back in the day.
Gerber (or CMG) used to make the Infinity with an amber emitter, which is very helpful for camping as it doesnāt wake people up like a while/blue-white light source will do.
Look inside the tailcap if you get a Gerber ā some models will have a + indicator to remind you to put the battery in ābackwardsā to the usual direction.
I donāt remember ever actually seeing a Gerber branded āregularā Infinity. I only saw the CMG version before Gerber bought them out. Still even the Ultra is only rated at 8 lumens.
I remember one thread on SPF where an owner was still getting usable light after 72 hours.
I like my AAA Fenix E05 for it's low 8 lumens output. Not much of a perceived difference to 5lm. The other 25lm and 85lm output requires quick twist off/on less than a second. Not many adults realize this, should be pretty hidden for kids. The quality also very good, made to last. VERY efficient on it's lowest setting. It's on AAA, should equally easy to find as AA too.
EDIT: swapping to any high CRI LED will reduce the output closer to your 5lm spec (bonus light quality)
