The section at the bottom of the back of the package where the patent information is refers to a "2-cell AA flashlight". The model number on the top is "M2A01HR" which is very similar to the "M2A01H" which is a "AA HOLSTER COMBO, BLACK" according to www.maglite.com - but the Mag site doesn't actually say it's a 2-cell light. I don't know what the "R" means (retail? red?).
