I see there is a tube extender to house AA battery in my Mr Elfin.
seeing how it operates on an 123 3.7volt battery.
is there any reason with the tube extended.i couldn't use a 14500?
I have a tan M11R, two V11Rs, had a tan V10R and I have two AA extenders for them.
I don't use them, as it defeats the shortness of the light, for me. In fact, the M11R isn't all that much brighter on a li-ion AW IMR that I use, than on a CR123A.
Certainly not like the difference with a V11R/V10R on li-ions vs. CR123As, where the light is almost twice as bright on paper.
While the Sanyo UR14500P has more capacity, it's just not worth the effort, but I do have them and I can use AAs/14500s if I have to, so that's a bonus and why I bought them while on sale. Not because I want to EDC the lights with the AA extender tube.
