A23 battery's are tiny, cheap, and have 12volts. I know they have very small capacities but what other reasons are there for not making an led flashlight that uses these. Especially in times where led's are able to use these higher voltages. Can you not run these in series or in multiples to get better run times? I would love a truely nano light that uses these even if the output isn't astounding.Or maybe something along the lines of the streamlight cr2 nano. Or maybe even a 1 Cr123 sized light running 3 A23's using a p7 or MC-E. Thanks for any input. Would definately be interested in purchasing lights like these.
