SureFire has manufactured tactical illumination tools in the USA since 1979, starting with laser sighting systems before moving to high-output LED flashlights. The brand builds every flashlight body from aerospace-grade aluminum with Mil-Spec hard-anodized finishes that resist corrosion and abrasion. O-ring seals and tempered glass windows protect internal components. Most models meet IPX7 waterproof standards for submersion up to one meter for 30 minutes. This construction philosophy comes from SureFire's experience supplying military special operations units and law enforcement agencies that need lights capable of functioning in combat environments.
EDC and Tactical Handheld Models
The Stiletto series uses slim polymer bodies with aluminum heads for pocket carry, delivering 1,500 lumens in the Pro II configuration through integrated rechargeable batteries. Fury models feature knurled aluminum bodies and micro-textured reflectors that create smooth beams with bright central areas and sufficient surround light. The E1B Backup runs on a single CR123A battery with dual-output LED producing 400 lumens on high and 5 lumens on low for extended 50-hour runtime. Titan Plus models use nickel-plated brass construction with twist-activated head switches for three output levels: 300, 75, and 15 lumens. All tactical models include reversible pocket clips and tempered window protection.
Dual-Fuel Rechargeable Flashlights and CR123A Systems
Most SureFire handheld models accept either two CR123A lithium batteries or a single SF18650B rechargeable lithium-ion battery. The SF18650B batteries have integrated micro-USB charging ports, removing the need for external charging cradles. CR123A configurations typically deliver 1,100 to 1,500 lumens depending on the model. Rechargeable batteries can reach 1,500 lumens with extended runtime up to 40 hours on lower settings. The G2X and 6PX series use compact two-cell CR123A designs. Models like the Stiletto Pro use proprietary rechargeable lithium-polymer batteries with LED fuel gauges that show charge status.
Scout Light Weapon-Mounted Systems
The Scout Light Pro series mounts to MIL-STD-1913 Picatinny and M-LOK rails using SureFire's Low-Profile Mount system, which lets users position lights around other rail-mounted accessories. Scout Light models generate 500 to 1,000 lumens with TIR lens systems that balance throw distance with peripheral spill light for indoor and outdoor use. The M640DFT-PRO Turbo variant produces 100,000 candela peak beam intensity for long-range target identification beyond 300 meters. Z68 tail cap switches provide momentary and constant-on activation and are compatible with remote pressure pad switches. Scout Light Infrared models have rotating bezels that switch between 350-lumen white light and 120-milliwatt IR output for night vision device use.
IntelliBeam and MaxVision LED Technologies
SureFire's IntelliBeam technology uses microprocessor-controlled sensors to automatically adjust LED output from 15 to 1,500 lumens based on target distance and ambient conditions. Models like the Fury IntelliBeam eliminate manual output selection by continuously evaluating the environment and adjusting beam intensity in real time. MaxVision Beam reflectors have precisely engineered facets that spread light across the user's field of vision instead of concentrating it in a narrow spot. This reflector design creates a uniform wall of light, ideal for close-quarters situations where situational awareness matters more than throw distance. Total Internal Reflection (TIR) lens models use molded cyclo-olefin polymer optics to gather nearly all LED output and shape it into high-candela beams for longer-range applications.
