Its not only the output, which I would like in the 600-1000 lumen-ish range, mostly with a good hotspot and decent spill. The biggest point though is a host that can withstand HEAVY abuse. It gets dragged around outside of my vest, down on the ground, in and out of vehicles and aircraft, saltwater, and chemicals. It may be used as a striking implement like a ku-baton. I know this is a lot out of a “budget” light but this is the place to ask I reckon. I dont have to tell you guys how many Maglights we go through. They just dont stand up but they have plenty of them to issue us.
