I just tested some single AA flashlights to see how long they last if you just start them on high and let them run. I hate flashlights that just die on you without warning. Its so much better if they go from high/medium/low so that you have time to change batteries before they're dead. I used the same Alkaline AA batteries all round and checked that they registered 100% on my ZTS Tester.
Eagtac D25A - This was dead in an hour. The battery tested at 0%. I repeated the test but got the same result.
Acebean Pokelit - This was dead at about 1 hr 45 minutes. The led was still glowing but produced no meaningful light. Battery tested at 40%. I repeated this test too and after over 2 hrs 45 minutes its still producing meaningful light.
Olight i5T - After 6 hours this is still producing meaningful light. By that I mean that in low light conditions you can still light up the other side of the room.
Klarus Mi7 - Same as the Olight. Still going strong.
The surprise was the Lumintop tool AA V2. I have a few of these and tested 2 of them. The grey one died at about an hour. I repeated the test with the same result. Battery tested at 40%. The silver one is still going strong after 6 hours like the Olight and Klarus.
Now my test wasn't very scientific but it does tell me that I won't trust the two that died at one hour. It also goes to say that you can't generalise about any flashlight until you've actually tested the one you own.
Interestingly I also have an old Fenix LD41 that I never use. I put 4 of the depleted batteries in it and after 2 hours it too is still producing meaningful light. Obviously a vampire.
