Maxtoch Shooter 2X and Maxtoch M24 (both use 2 x 18650) and both will run in highest setting (1200 to 1400 lumens) for 80 minutes average with NO step down and easily reach to see human or human sized objects ,well beyond what the naked eye usually is able to see with a flashlight (unless using binoculars or such). Both maintain Medium mode (900 to 1000 lumens) for around 2 hours and both reach well over the 200 ft mark even in the low setting of 250 lumens for 12 plus hours.
Both have been upgraded for better output and runtime since my reviews were done but here is the reviews of both those lights.
