I just received my NiteCore EZ AA and can confirm it DOES fit in an altoids tin. You'll have no trouble with the AAA lights as every one I have fits in the tin. The EZ AA is my first single AA light so it is the only one I can comment on. Although I did pick up a single AA tube for my Fenix 2 AA light. I suspect it will be a little too thick to fit and might only fit diagonally for length. I will confirm when I get home and get to try.
