Alright guys I need your help to find the highest quality single cell AA light out there. To me high quality would be like HDS and Surefire. Both of these brands seem to make some of the toughest most reliable lights out there however none in single AA format. Now don't get me wrong, I own or have owned various models of foursevens, fenix, nitecore, zebralight, and Jetbeam that use single AA and love them but are these the highest quality out there? Thanks for the help guys!
