2 precision reflectors & lenses

SureFire reflectors are made from machined aerospace-grade aluminum for superior strength and heat-transfer capabilities, not cheaper stamped metal or molded plastic. Their proprietary designs and geometric exactness help produce optimal beam characteristics that lesser reflectors just can't achieve (see Outshining & Outperforming).

Micro-texture ripples, which reflect light at many slightly different angles, cover the surface of every SureFire reflector. This coating, similar in texture to the peel of an orange, smoothes out beam irregularities and produces a bright central area surrounded by a gradually diminishing corona. The resulting beam clearly illuminates objects in its center while providing more than enough light to accommodate peripheral vision.

Total Internal Reflection (TIR) lenses are placed over LEDs in certain SureFire illumination tools. Made from a precision-molded cyclo-olefin polymer, the lens gathers virtually all of an LED's light, which it reflects and refracts forward in an exceptionally tight beam that simply can't be achieved with a reflector.

[m optically coated pyrex® windows

If you've ever cooked with tempered Pyrex glassware, you know that it's strong, scratch resistant, and can take extreme temperatures (and temperature changes) without cracking. SureFire flashlight windows—the transparent coverings that protect reflectors and emitters from the elements—use this same tough glass. Pyrex windows have a thin anti-reflective coating to make sure as much light as possible makes its way out the window and on to the object being illuminated.

Dark spots, hot spots, and rings may cut it with most flashlight manufacturers, but SureFire believes flaws like these demonstrate a serious lack of character in a beam. A beam's characteristics determine a flashlight's suitability for a given task. Inferior beams can produce views that are confusing or even misleading. SureFire beams are engineered for optimal light distribution—without glaring defects that can interfere with an illumination tool's ability to perform the task at hand.

^ aerospace-grade aluminum bodies

SureFire flashlight bodies are machined from a high-strength aerospace-grade aluminum alloy, allowing them to be made light without sacrificing toughness or durability. An aluminum SureFire flashlight body is extremely resistant to damage from impact, crushing, or bending.

Nitrolon® is a proprietary high-strength, non-conductive polymer used in some of SureFire's flashlights. It's made from a mixture of nylon and fine glass fibers, which add rigidity, strength, abrasion resistance, and increased stability at higher operating temperatures.

5 mil-spec hard-anodized finish

How do you make an already tough aluminum body even tougher? Try a hard-anodized finish that gives diamonds a run for their money when it comes to hardness. Using a chemical bath and electricity, a layer of aluminum oxide is "grown" on the aluminum bodies of SureFire illumination tools. Anodized finishes come in varying degrees of hardness, but to ensure that SureFire illumination tools are as tough as possible, we use military-specified finish Mil-A-8625, Type III, Class 2. That's military speak for tougher than nails.

Q tactically advantageous switching electronic power regulation

Every SureFire LED illumination tool (and the xenon-lamped A2 Aviator®) has an internal electronic power regulator that oversees the operation of the emitter. This sophisticated circuitry assesses battery output, monitors system performance, and controls the power supplied to the light source. What this means to you is more consistent light output for the usable life of the batteries. And you can brag to your friends that your flashlight has a computer inside of it.

Holding a flashlight with your thumb over the switch provides precision control—a tactical advantage for law enforcement and military professionals. So SureFire positions its switches on the tailcap instead of the flashlight body. While a switch you press for momentary-on and twist for constant-on makes sense for tactical applications, some people prefer a click-on/off switch. Several SureFire flashlight models can accommodate both types, so you can rig your light to switch on the way you want.

3 lockout tailcap

Your flashlight doesn't do you much good if it's wasting its batteries illuminating the inside of your drawer or suitcase, so SureFire tailcaps have a patented lockout feature to keep your light from accidentally activating during storage or transport. Just rotate the tailcap counterclockwise to disable the activation switch. When you're ready for action, rotate it clockwise to re-engage the switch.

s lithium batteries with 10-year shelf life

Non-rechargeable SureFire flashlights use 123A-type lithium batteries, which have several advantages over alkaline batteries (see below). As a commitment to our customers and products, SureFire sells its own brand of highest-quality lithium batteries at a low price. And because they last for 10 years or more on the shelf, there's no worry about overbuying.
