Maximum lumens of flashlights using AA or AAA batteries?
Does anyone have idea about the maximum lumens a flashlight is capable of, which uses several AA or AAA batteries? I have one that claims to be 800lm but obviously much less in reality, however I have no idea how many lumens it actually has. If I know the maximum lumens, I'll know all those claiming more than that are lies, and that if I want brighter ones, I can't expect to use AA/AAA's.
