Question: On their helmets were two torches (flashlights). The bigger light had two options, an LED cluster and a standard bulb. Wouldn't the battery have lasted longer if they chose the LED option?

Chosen answer: Being someone who uses the PETZL Duo headtorch (the light used in this movie) I can say that yes, the LED option lasts MUCH longer than the standard bulb.
