I was fiddling around with some near dead AAA and AA alkaline batteries
I drained dry in a dorcy and old style xnova AA 8LED and wondered if I could
get any more useful runtime out of them and popped a AA in a green LED CMG infinity and it ran it for many hours till it dimmed to nothing. After turning it off for a day it ran for perhaps 30 minutes in the light again and I go to thinking..... I wonder if the battery would even light up my fenix so I popped it in and was impressed it lit it up bright enough to be useful and for a long time also. Measuring the current at the tail was 40-50ma.
I then took a AAA that a dorcy sucked dry and stuck it into the fenix and it was even brighter.
I wonder if any other boost circuit/LED cominations work even better at very low input levels.
