I use the high or turbo setting so I can make out what is behind those eyes that stare at me in the very remote area I inhabit. The Olight SR 51 is the minimum I use then the TK70 or SR90. I may buy the new model if anyone can convince me it is a significant increase of flood & throw compared to what I have. I have heard reports about the new Surefire 2200 lumen (Dominator) being on par or exceeding HID territory. Will have to see the price on that one.
