I've just seen "1917" and when Schofield and Blake were in enemy trenches - the rat tripwire scene - they were using some portable lamps.

My question is - how realistic is this depiction and if it is realistic - what were technical specs of these lamps? They are supposedly electric but I’d be very surprised if they last longer than half an hour.

I believe that is called a Beacon Army Light and just from cursory google searches on the topic the movies seems to be authentic to the time in terms of flash light technology.

Also found this one that looks like it says they last around 5 hours pretty neat!
