The M6 Guardian is the brightest lithium powered flashlight
SureFire makes. This light uses six lithium batteries in a
quick-change magazine to produce light so stunningly bright that
police SWAT teams use it to temporarily blind and unbalance hostile
subjects. The M6 comes with two interchangeable lamp assemblies
producing either 250 lumens for one hour or a devastating 500 lumens
for 20 minutes (30 times the light output of a typical two D-cell
alkaline flashlight). The M6 also features a 2.5-inch TurboHead
reflector to tightly concentrate the beam for longer-range
applications. Like all lights in SureFire's Special Operations
Series, the M6 Guardian Assault Light is CNC machined from
aerospace-grade aluminum, coated in a super-rugged military
specification Type III hard-anodized finish, and includes a
shock-isolated bezel/lamp assembly that can withstand the repeated
recoil of a large caliber weapon. The M6 also features unique
switching originally developed for law enforcement- twist for
constant on, or depress the tailcap button for momentary
illumination or emergency signaling.
