<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>but some of you are talking about an AAA. Which one is it? <HR></BLOCKQUOTE>
JoeyL - I suppose your confusion is my fault for not being more clear when I brought up the AAA option in the first place. Sorry.
I think most people put 3 N batteries in the AA MiniMag when doing this mod and then add an electrically conductive spacer or longer spring to hold the batteries in place and maintain a good electrical contact.
I like to use two N cell batteries and one AAA battery in my AA MiniMag mod. No spring or spacer is needed, it costs slightly less and gives me a little more battery capacity than 3 N cells.
Both options kick out 4.5 volts and overdrive a standard Nichia 5mm white LED some (which I like).
Klaus's suggestion to use AA lithiums will give you much more battery capacity and it doesn't overdrive the LED much at all.
N cell batteries do not fit into a AAA MiniMag light.
It's a nice, lower-light-level, easy mod, no matter which power option you choose .
