I have a collection of Streamlight Flashlights

Read this info on Streamlight flashlights. I think I have almost one of every streamlight flash light product. It is very interesting information on streamlight and their flashlights...they definitely stand behind their products!

Streamlight flashlight is a “hands-on” company. By doing so, we understand what our customers need because we’re out there doing what they do, using the same lighting tools in the same ways. We go through firefighter's training. We take courses in low-light shooting. We’re hunters, outdoorsmen, fisherman and sports enthusiasts. Brad Penney, our president, takes his Streamlight flashlight on his many hunting trips. Our sales director for the hunting and fishing markets is an avid hunter. Many of our law enforcement sales managers are gun collectors, hunters and competitive shooters. We believe it’s our hands-on, real-world experience that leads to new ideas and innovations that set Streamlight apart.

Who knows what we’ll come up with next?

We Listen. We Learn. We Get It.
We make it a point to get out in the field and talk to our customers. We hold focus groups to hear what they like about our products; but we’re more interested in what they don’t like, what needs to be improved, and what lighting problems have yet to be solved. Customer feedback helps us continually improve existing products and create new and better ones. Since the most extreme hazardous conditions are often in dark places, Streamlight created a complete line of safety-rated lights. For the industrial market, we’ve developed lighting tools that are safe to use even around explosive gases and in other potentially explosive atmospheres.

Auto technicians can now easily see into the smallest, darkest engine crevices, thanks to the Streamlight Stylus Reach, a powerful, lightweight penlight with a flexible cable. Our green LED clip-on penlights and headlamps are keeping outdoor enthusiasts safer, with an LED light so strong, it’s visible from over a mile away.

We Didn’t Invent Customer Service; We Just Perfected It.
Our success is directly related to our ability to satisfy customers. So we take customer service very seriously. Our inside sales department includes specialists in each of the markets we serve. They go through extensive training on all our products, even working on the assembly line and in the repair shop. They know Streamlight products inside/out. They understand the challenges you face and they know how to help you find the best lights and get the most from your purchases. We’ll work with you and do whatever it takes to help you.

We Support Our Products With A “No Excuses” Warranty.
Streamlight makes tough, durable, long-lasting lights. And we support them with an equally strong warranty. If something goes wrong, we don’t make excuses – we make good. Streamlight warrants its products to be free of defects for a lifetime of use. We will repair, replace or refund the purchase price, at our option, of any Streamlight product that does not work or that you manage to break for as long as you own it. Of course, this limited lifetime warranty excludes abuse, batteries, bulbs and chargers. Rechargeable batteries and chargers have a 1-year warranty.
In the unlikely event that you have a problem with a Streamlight product, go to www.streamlight.com for the location of an authorized Streamlight repair center near you.

World-Class.
It’s no wonder that Streamlight is recognized around the world as the leading provider of premium portable lighting solutions. Our products are distributed in over 60 countries, and our website is available in four languages.

Surefire LED Flashlights - very interesting information!

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.
