The Streamlight TLR-4 tactical laser is a compact, rail-mounted light/laser combination designed to be used as both an illumination aid for low-light shooting as well as a laser sighting device for use with a range of the world's most popular pistols. The innovative light, which boasts an overall lifespan of 50,000 hours, utilizes a C4® LED that delivers a peak beam intensity of up to 5,000 candelas and 110 lumens. It is powered by a single 3V CR2 lithium battery, and provides up to 1 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.
The powerful 660 nm micro laser is designed for long-range precision targeting and may either be used alone or in conjunction with the C4® LED light. When used alone, the laser may run for up to 11 hours of continuous use. Like the light, the laser offers ambidextrous controls (three-position mode selector), full point-of-aim adjustment and excellent sight retention.
These electronics are housed within an ergonomic case that measures 2.73 inches in total length. 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-4 is waterproof to one meter for up to 30 minutes and carries an operational temperature range between -10 degrees Fahrenheit to 120 degrees Fahrenheit.
