The phrase is "vampire light" or "vampire circuit"

Looks like that has an ordinary bulb; anyone do a test showing lumens? I presume it has no regulation.
The now discontinued Nitecore EZ AA would drain alkaline cells dry. (You can advertise that you're looking for one in the "Want To Buy" section of this forum.)
The ThruNite T10, and the ThruNite Saber 1A will also drain alkaline cells to the point that they beg you to put them out of their misery.
Finally, the 4Sevens Mini AA will also drain cells in similar fashion. The original version (with trapezoidal threads) didn't have a low voltage cutoff, if I remember correctly (no guarantee on that last point however).
Happy hunting.

Does your friend use up batteries after being in toys for children?
I have a flashlight Malkoff 1AA, it is very economical and was able to drain the AA battery to 0,6V, after a while the battery is restored, when the battery recovers above 0.8V, it works, when the battery recovers after 0.6V to 0.8V or less - it does not ignite. He was able to use the battery for 2 hours, who could no longer move the hand of the table alarm.
The best thing in my opinion is to find an adapter for 3 * AA in flashlight body for 3R12 battery
and use the diode and guts from this lantern for a 1.5 volt battery, for example from inova microlight, or https://laughingrabbitinc.com/index.html
Then your friend will get some number of photons from dead batteries
as a case for such a Frankenstein, you can use a German military flashlight
But, what is important here, you will have to use only dead batteries, if he installs fresh batteries in a similar structure, he will be able to kill the diode, or maybe not, I have not tested it yet

or you can make a test construction like this - 3r12 adaptor + wires + glue + 1.5V small flashlight
a friend of mine made a similar one out of an unnamed flashlight and a auto battery for stationary use
times have changed, now this adapter calls "aa battery holder"
