I can recall when MagLite flashlights were the most prestigious and high quality flashlights to have. There were your run of the mill D-cell flashlights in plastic casing of various primary colors, and then there were the heavier duty MagLite flashlights, of which even the smallest outshone the plastic common flashlights. Then along came SureFire, which put MagLite to as much shame as MagLite put the plastic flashlights.
(or "illumination tools") are quite expensive, ranging from around $70 to over $400, but from customer feedback they are worth every penny. Customers include many police forces, professionals, and military, which is not surprising considering SureFire flashlights are made to military specifications. The construction of SureFire flashlights is impressive, using only the highest quality available for each component. Some are even designed to aid in self-defense!
The most robust of SureFire's illumination tools are the WeaponLights. These flashlights are specifically designed to withstand the rigors of small-arms fire such as vibration and shock. Special shock absorption technology is utilized to protect WeaponLights that use incandescent light bulbs, while LED SureFire flashlights
require no additional shock absorption due to the inherent stability of LEDs. Aluminum-body WeaponLights make use of machined high-strength aerospace-grade alloy constructed of anodized aluminum. These anodized aluminum bodies are extremely resistant to damage from impact, crushing, or bending, which has the added benefit of allowing the flashlights to be as small and light as possible without sacrificing strength.
The commitment to quality displayed by SureFire extends even to the batteries which power their flashlights. SureFire sells its own brand of quality 123-type lithium batteries at very low prices. WeaponLights and non-rechargeable flashlights use these lithium batteries because of their advantages over alkaline batteries. These advantages include shelf life, temperature tolerance, power density, weight, voltage, and voltage maintenance. While using such high quality components does increase the cost of the light bulbs, this is definitely a situation in which "you get what you pay for"; these flashlights will not break down, and it is extremely difficult to damage them in the slightest.
If you need a flashlight for any reason, SureFire flashlights are your best bet. Use one of their line of high quality, rugged flashlights and you will never use another brand.
