Hi Firefly,

Survival lights are designed to give a long duration of light (not maximum brightness)


It can also be extremely useful to allow the flashlight to give the maximum brightness in certain conditions. For example if you are stranded in the wilderness at dusk/nightime and you can hear the sound of a search aircraft in the distance, then an SSC P7 type flashlight flashing an SOS at over 600 Lumen for 2-3 hours would be preferred over a Maglite AAA Solitaire.
