Very nice light very sturdy light it does not change focus which i preffered when using 26650 battery it runs 45 hrs on hi from what i am using it so far

As a mechanic i have tried lots of this type of light so far this ones taking the beating and works great personally the only flaw is honestly dont need all the settings of himedlowstrobesos but it only switches to them if you push switch quickly if you let it set a few minutes it starts at hi again good shipping exactly as described not a super bright led flashlight but brighter than any standard bulb type i have ever owned
