How quickly does the light output fall as a battery loses charge in a LED flashlight?
Does light output fall quickly with a small discharge? Or does it stay reasonably good and then suddenly start to get a lot worse?
Has anyone produced a chart of light output against remaining battery charge?
(If the LED makes a difference then I'm thinking of something like a Cree XM-L LED.)
