My wife is going to India in a few days. She's Indian, knows how to travel, and generally is in very secure situations. But sometimes she does travel in rural areas to see her family. Tasers are illegal in India, so I figured I would get her a tactical light.
I've always carried guns and knives for defense, and frankly have not given a light much thought. I bought her an Olight M20-X Warrior. Color me impressed. The light on the highest setting is blinding, even in a lit room. The strobe light in indeed disorienting, very much so in a darkened room. The bezel on the thing is wicked. Large, reasonably sharp serrations. A blow to the head or face would be awful.
I was a bit hesitant to pay $$$ for a flashlight, but this thing does feel like the build quality and engineering are there to justify it.
