For most tasks, SureFire’s pocket-size, handheld LED flashlights are more than capable; however, when “extreme” output is needed, such as for long-distance viewing, searching, or overwhelming an aggressor, the U.S.-made 900-lumen M6LT Guardian has no peer.
Thanks to an LED emitter regulated to maximize output and runtime, with its six 123A batteries the Guardian has a “tactical runtime” of 3.25 hours. Its Turbohead TIR lens increases reach by focusing the beam, and a coated, tempered window maximizes light transmission. As impressive as the unit’s output is, its 8.2-inch length, 2.5-inch width (at the bezel), and 17.1-ounce weight are quite manageable.
The Guardian’s body is machined from aerospace aluminum, features deep grooves and ribbing to enhance purchase, and is Mil-Spec anodized. Activation is by way of a push-button tailcap; depressing the switch enables momentary-on, while twisting the tailcap clockwise results in constant-on mode. An O-Ring and gasket sealing ensure the Guardian is weatherproof. Six SureFire 123A batteries are included. Price: $425.
