Superb defensive light - SureFire Weapon Mounted Scout Light w/Intelli Beam 600 Lumens

This is an excellent light for rifles and shotguns used in a mix of indoor and outdoor defense. Price aside, this may be THE best light for that use. The responsive brightness technology is impressive, nearly imperceptible, and really does cut down on blinding yourself indoors. It responds much more smoothly and less noticeably than my older Petzl headlamp; you really need to creep it off a corner to see the spill's brightness as the hotspot stops reflecting.

This light is perfect for use indoors and at medium ranges. No, this isn't a light for razor-sharp target identification at 200yds, and you might not want that blinding bounceback on a gun used indoors. This will easily go from sweeping a room without making you squint, to lighting up a suburban yard or half a city block.

Since it doesn't seem to be noted anywhere official (?), this includes a small spacer that seems to be for pushing the light about 1/8-1/4" away from the mount. This may be to make a little more room for the larger head.
