Just a humble observation from someone who has spent quite a while with the "tactical" side of things: While you shouldn't skimp on a weapon-mounted light because of the repeated shock and abuse it takes from recoil even when the light itself isn't used, if you plan to carry a handheld light, you don't need to worry about spending big bucks to get decent quality. I have everything from Surefire E2 executive and its pocket clip that regularly gets bent and broken because it snags on everything, to the M6 Guardian with its 500 lumen bulb to the Gladius with its strobe feature. ADD moment: Did you know the strobe can be largely negated by shining another flashlight on it? For those of you doing any training where the cadre has you entering a room with a strobe light in it, have one guy hit that strobe with his weapon light while the others clear the room. You're welcome. I have found that unless you plan to retake Iwo Jima or use your flashlight as a hammer regularly, there isn't much practical difference between the spendy pocket lights and the 25 dollar S&W LED lights or even, as I have recently stocked up on, the 8 dollar 3 x AAA LED lights at Lowe's.
