Streamlight Inc. is an American-owned and operated manufacturer that specializes in handheld and weapon-mounted lights, each of which is powered by various rechargeable and disposable batteries. For years, the company has been dedicated to translating hands-on, real-world experience into new ideas and innovative products that find use in a wide range of markets, including law enforcement, firefighting, outdoor sports and even civilian use. Recognized as a global leader in the industry, their products are distributed in over 60 countries worldwide. The company even developed the first million candela hand light for NASA in the early 1970s. But their dedication to research and development is only part of the story. Streamlight cites their success as a direct relation to their ability to satisfy customers. As such, the company strives to meet the needs of their customers, whether through targeted sales or the utilization of customer feedback to improve the line.

The Streamlight TLR-1S tactical light is a compact, rail-mounted light designed to be used as an illumination aid during low-light shooting with a range of the world's most popular pistols. This innovative light utilizes a C4® LED that delivers a peak beam intensity of up to 12,000 candelas and 300 lumens. It is powered by two 3V CR123A lithium batteries, and boasts up to 2 1/2 hours of continuous use. With a range and brightness comparable to a xenon bulb, the C4® LED is said to be two to three times brighter than high-flux LEDs. Lighting is also aided by a unique parabolic reflector, which produces a concentrated beam for optimal peripheral illumination, giving you a complete view of your immediate surroundings. The light is manipulated by ambidextrous controls that provide for both momentary and steady on or off. Moreover, tapping the momentary switch twice simultaneously activates a strobe feature that is not included on other models.

These electronics are housed within an ergonomic case that measures 3.39 inches in length, 1.47 inches in width and 1.44 inches in height. It is constructed from a tough, impact-resistant polymer and includes a face cap that is constructed from 6000 Series machined aircraft aluminum with an anodized finish. It may also interest you to know that the TLR-1S is waterproof to one meter for up to 30 minutes and carries an operational temperature range between -40 degrees Fahrenheit to 120 degrees Fahrenheit. 

As noted, the Streamlight TLR-1S tactical light is designed for use with a range of the world's most popular pistols. This is achieved through the inclusion of a range of interchangeable mounting keys that make this light compatible with:

- Beretta 92 Series/Px4 Storm

- Kel-Tec PF-9

- Kimber TLE/RL II

- Glock

- Smith & Wesson M&P Series/99 Series

- Springfield 1911/XD Series

- Many more…

Awesome weapon light
Review by Yetunde N.
<span>I use this light on my duty weapon at work and it does everything I need. I particularly like the strobe feature on this light. It is not so bright that you lose all of your night vision but bright enough that it lights up your target. Great product. Mounted perfect to my Glock 22.</span>

Bought two. Here's why;
Review by Terrance O.
<span>Amazing water resistance, IPx7 I believe. Great battery life. Uses common batteries. Bright as heck. Flush end with a standard CZ SP-01. The one thing I like about it more than surefire x300s from what I've seen, isn't just the price, but how compact it is, and how it's incredibly durable and waterproof, as much as a surefire x300. 5/5 stars in all categories. Will update if anything goes wrong.</span>
