Streamlight TLR-1 Rail Light

've waited till the BS and dust has settled before I committed to a weapon mounted light system and I'm glad I did!  Here's the best I've found - the Streamlight TLR rail-mounted tactical light - Made in the USA.  LED light source, 3-watt 80 lumens (no, this is not a mis-print) and the deep-dish parabolic reflector pushes the light out for long range targeting.  The LED lamp is way more shock-resistant than a incandescent lamp and has a 20,000 hour life.  Uses 2 3-volt lithium batteries.  Momentary or constant switch on back.  One hand snaps light to handgun/rifle and tightens thumb-screw -- and since the screw is on the side it keeps your fingers away from muzzle.  Fits to all Glock-style rails and all Picatinny rails (MIL-STD-1913).  Total weight 4.18 oz.  Constant-On battery life: 2.5 hours.  Waterproof to 1 meter.  Streamlight offers their "No Excuses" limited lifetime warranty.
