CombatGrip™ design for use with a handgun; ultra-bright, five-watt LED for performance, click-on/click-off switch for convenience. Whether you're flying an F/A-18, assaulting a beachhead, or simply walking the dog, the L5 LumaMax won't let you down when the going gets tough. Powered by two lithium batteries (10-year shelf life), the L5 is equipped with an ultra-bright, 5-watt LED that produces a maximum output of approximately 65 lumens (more powerful than typical four D-cell alkaline flashlight) and over 3 hours of total useful light. CNC machined from aerospace-grade aluminum and coated in a military specification Type III hard-anodized finish, the L5 utilizes an ergonomic flat-side CombatGrip™ design and a patented rubber grip ring so that the light can be operated with a handgun using the Rogers/SureFire technique. The L5 features a new click-on/click-off tailcap pushbutton switch that gives the user the tactical advantage of momentary activation or the convenience of a constant-on “click” switch in a single switch. The L5 also features digital current regulation circuitry to match the LED's current requirements with the battery's output to maintain a more consistent level of light output for the useable life of the batteries (as opposed to unregulated lights, which are subject to a steady decline in light intensity beginning shortly after activation). • Batteries - Two lithium 123A 3.0 Volt with 10-year shelf life (included) • Output/runtime - Maximum output of 65 lumens white light for one hour, followed by over 2 hours of useful light. Total runtime 3+ hours. • Construction - CNC machined aerospace-grade aluminum. Hard anodized finish for extreme corrosion and wear-resistance. O-ring sealed, Pyrex® lens, steel pocket clip • Length and weight (with batteries) – 6” / 7.2 oz. • Bezel diameter: 1.47” • Flawless beam, always in focus, no dark spots or rings • Patented lock-out tailcap allows the light to be locked in the off position to prevent unintentional activation during storage or transportation • Patented rubber grip ring and flat side CombatGrip™ body style, so that the Rogers/SureFire technique can be used to operate the light with a pistol • Self-defense tool – bright enough to temporarily blind an opponent • No Hassle Lifetime Guarantee: If it breaks, we fix it!
