All flashlights are capable of falling out of your hands and that’s why you’ve always seen head mounted flashlights.  Many of my mechanic buddies use head mounted lights because things can get dropped into engines which can become a nightmare situation.   I actually know someone that was in a lawsuit with an auto repair place after someone dropped off a car to get a speedometer and spark plug change and ended up with a destroyed transmission.   The mechanic apparently tried to hide the fact that he dropped a screw into the engine and then turned it on.

Firearm and police can give you plenty of situations where lights have failed or broke on duty and each style of flashlight has its pros and cons.  Streamlight flashlights for sale can give you a selection of anti-roll and drop protection but not everything will work in every situation.   I have been a fan of flashlights like the Professional Series PT-2L for ccw but recently discovered that the one that I carry has a cracked lense.  Not too happy about that since it’s only been carried for a year, but we’ll see how much of a headache repairing it is.
