I have tried several and the ones I like the most are the Nitecore Tube, Tip and Tini, but I don't consider them to be reliable enough for EDC. Two tubes and my Tip died on me and I found them on or with a dead battery from accidentally being switched on fairly often. I'm looking for something similarly sized and priced with a 1 or less lumen mode. If it's two modes I would like the high to be about 50 lumens or more and run time of at least an hour. If it has more than two modes I'm fine with medium having less than 50 lumens as long as high is about 50 lumens or more. I'm also looking for USB charging and button(s) for switching. Thanks.
