Using a flashlight as a defensive "weapon" has always been a [FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]controversial[/FONT] topic. But things are changing, as some of the lights we are getting now are unbelievably powerful. Getting my Acebeam K75 has changed my way of thinking on this subject. Conducing a scenario where I tried approaching my brother at night, with him having the K75 on Turbo was a real eye opener (or closer for that matter).
6300 lumens of 1.5 million candela in a eye scorching hotspot so intense it's unreal, and a quick, easy, and reliable way of instantly getting Turbo mode at any point, has made the K75 my bedside light. Having a dim, 2 lumen mode for trips to the bathroom at night is the cherry on top.
Of course, I would not trust defending my family to only a flashlight, and I don't recommend you do either. That's where the customized Glock 21/Benelli Supernova comes in.
But make no mistake, the K75 most certainly instills much confidence for those bump in the night type times!
