Who knows exactly what an LED flashlight is? Well, read this and inform yourself.
Light-Emitting Diodes (LEDs) An LED (the acronym for Light-Emitting Diode) is a semiconductor “chip” that converts electrical energy directly into light. An LED is called a solid-state light source because it has no gas or liquid components, as do other light sources. The LEDs in SureFire flashlights consists of the emitter chip mounted on a solid base; the chip is attached to electrical leads (wires) that conduct power to it, and it is encased in a clear polymer that is shaped to either focus or disperse the LED’s light in the desired manner. LEDs generally emit light within a narrow spectral band. In order to produce white light, which consists of the entire visible spectrum combined (or nearly so, as far as the human eye can discern), we use LEDs that emit near-ultraviolet blue light that strikes an upper layer of phosphors. These phosphors absorb the blue light and re-emit white light, in much the same manner that fluorescent light tubes produce white light. LEDs possess some tremendous advantages over incandescent lamps.
First, LEDs can last thousands of hours versus less than fifty hours for high-output incandescent lamps.
Second, because LEDs are very robust in construction, and have no mechanically delicate parts such as glass bulbs, filaments, or filament supports, they are extremely resistant to vibration and shock, making them well-suited for the combat environment or for mounting on firearms.
Third, LEDs produce virtually no invisible infrared radiation, as opposed to incandescent lamps, which emit over 85% of their output as infrared, and therefore LEDs are much more efficient in producing light than incandescent lamps — an important factor for battery-operated flashlights.
And finally fourth, they will emit light over a wide range of power input making LEDs the natural choice for adjustable-output light sources.
As noted above, there are currently some disadvantages to Surefire LED flashlights sources.
First, most LEDs emit forward from a flat surface, necessitating more complex reflectors and lenses to produce desirable beam characteristics.
Second, because LEDs are susceptible to damage from overheating they have certain thermal design requirements. Therefore, continuous-use LED sources currently have a practical limit of less than 150 lumens.
Third, LEDs are difficult to manufacture without some variance in lumen output and color. For this reason, they are tested and sorted by the manufacturer into different “bins” according to output and color. SureFire minimizes such product variability by purchasing LEDs only from the highest-quality bins.
Electronic Power Regulation — SureFire's LED illumination tools contain a rugged, sealed electronic power regulator that supervises the operation of the LED (with the exception of the A2 Aviator, in which the xenon lamp is regulated). This circuitry assesses battery output, monitors system performance, and controls power supplied to the LED. Power regulation provides a more consistent light output for the useable life of the batteries. Although any LED may continue to produce negligible light output for up to several hundred hours, the amount of useful light produced is of a shorter duration. Power regulation circuitry reduces the amount of negligible output and increases the overall duration of useful light output.

Blackhawk law enforcement section - my new fav!
Introducing Blackhawk Law Enforcement Duty Gear.
It took the experience gained on the street, working as street cops, of the team at BlackHawk to finally get you nylon duty gear the way it was meant to be. With our group of field experts, from beat cop to tac officer, we know what you want and how you want it to look and perform. Along with the other folks at Blackhawk, who have decades of experience in R&D and manufacturing, we figured out how to give it to you.
Only BlackHawk has combined the crisp, professional look of molded nylon with the superior abrasion resistance of Cordura® nylon. You always had to settle for one or the other. Now you can get both.Abrasion is the main enemy of duty gear and regular nylon just doesnt hold up. Cordura® nylon has superior resistance to abrasion, but has always been easy to crush and hasnt always maintained its shape. BlackHawk has found a way to mold Cordura® nylon, so that you get that great molded look with the toughness of Cordura®.
Our special Cordura Ballistic weave nylon will look great day after day. It won¹t crumple or collapse when you take your baton or cuffs out and it won¹t get wrinkled from you simply using it in the real world.We also use a proprietary 5 layer laminate that is tougher than anything else out there. Instead of the usual 3 or 4 layer laminate, we have added an extra reinforcing layer that strengthens without adding bulk. This way, you get the strongest, best looking molded duty gear on the market and it will stay that way tour after tour.
Try our new duty gear for yourself. We think you'll agree that we've done duty gear the way you would do it. It really is "Police Duty Gear Done Right".
Blackhawk Duty Gear.
