Listen man, this is a tough question and obviously you are aware of that. However I have been through alot of lights and currently, I have a Quark Netural AA2x and I got the AA body. I am running it off a 14500. The output is
ABSURD. If I had to guess I would put it at around 400 lumens, with some throw out of a body a little bigger than a Chapstick. I work at a college and we have a baseball field obviously. I was using it the other night and I was lighting trees up on the other side of the field. Google maps lists it as around 535 feet. The output is really awsome. Comparable, dare I say, to my Malkoff M91W. Its an impressive tiny format. And here is a pic.
