Fenix L1T v.2 at 0145h this morning to put a (now empty) bottle of Australian Shiraz in the kitchen before crawling off to bed after having watched Avatar. All the house lights switched off hours before.
I've been using this light for house duty constantly for the last three months. It's a very good single cell battery vampire so I bring home handfuls of 'dead' AAs from work to drain the last photons out of. We test all cells handed in by staff on an Ansmann tester and anything under 40% goes in the recycle bin, anything over 40% goes in a 'part used' box. Only trouble is nobody but me would be interested in part used cells since capacities that low are only good for small LED lights. I end up with more than I can use but am loathed to get rid of them until they are really clinically dead. Last night/early this morning the L1T v.2 was running on an Energizer Lithium that was so low I got no reading at all on my home ZTS tester three days ago, and yet I still have high and low modes. I usually find that once high has gone, I have one evening left on low before the light flickers and then there's no more juice to relight if I switch off. If I leave it on, then it struggles an hour longer before falling off the lithium cliff. I guess it might soldier on even longer with an alkaline.
