  • The M6LT Guardian—a powerful LED upgrade of our incandescent M6 model—is a long-running extended-range flashlight featuring a tight 900-lumen beam focused by a 2.5-inch Turbohead TIR lens. The brilliant white beam can dominate potential aggressors by overwhelming their dark-adapted vision, or it can reach far into the night as an amazingly effective spotlight/searchlight that fits in a coat pocket. The M6LT's high-strength aerospace aluminum body has deep machined grooves to provide a secure hold with cold, wet, or gloved hands, and is finished with Mil-Spec hard anodizing for excellent corrosion and abrasion resistance. The tactical pushbutton tailcap switch provides secure, ergonomic activation control: press for momentary-on, twist for constant-on. The M6LT is powered by six high-energy 123A batteries held in an easy-load battery magazine.

  • 5 out of 5 Have always been a surefire loyalist and the M6LT is one of the reasons why. excellent reach, consistent white light and with the new LED bulb exceptional burn time/ lumen ratio. Another example of you get what you pay for. As always, when you buy a surefire product you get the absolute top shelf. Would love to find a fitted sheath for the M6LT. Would recommend this light to anyone and will be purchasing another in the near future for my other go bag.

About SureFire

SureFire collage The tale of SureFire can be traced back to 1969, when Dr. John Matthews established the Newport Corporation. Dedicated to harnessing laser power for industrial uses, the company soon grew to be a leader in the field. After much success, Matthews turned his attention to his hobby of shooting and developed the first laser sight, which would lead to the founding of Laser Products. It quickly grew after loaning the L.A. SWAT Team laser-sighted shotguns for security at the 1984 Olympic Games. Years of working with law enforcement agencies led to the first SureFire weapon-mounted flashlight. Armed with this advantage, tactical and military operations have never been the same.
