Compact and lightweight, the Streamlight MicroStream is a portable penlight with a super-bright, high-flux LED that lasts up to 30,000 hours. Featuring a tail-cap switch for single-handed operation, and durable and water-resistant materials for use in extreme conditions, the Streamlight MicroStream Penlight is ideal for daily use at home or at work.
Powerful Performance in a Petite PackageWeighing just 1.04 ounces, the Streamlight MicroStream Penlight is small enough to fit easily and comfortably in your pocket, purse, backpack, or tool bag. You can also clip it to your pocket for easy access, or use the included key ring or safety lanyard for convenient portability. Powered by one "AAA" battery (included), the MicroStream produces 20 lumens of light with a battery run time of 1-1/2 hours, and the 1/2-watt LED will last 30,000 hours.
The Advantages of LED Light
An LED is ideal for a light that gets used on a daily basis. You don't have to worry about breaking the light, since there is no glass or filament, and you rarely have to replace LEDs because they can last a lifetime. Save time and money on batteries as well--they will last much longer with an LED than with a regular light bulb.
Innovative Technology Provides Bright, Powerful Illumination
With Streamlight's specially engineered reflector, proprietary Micro Optical System (MOS) for optimized output and run time, and battery-booster electronics, the MicroStream produces a bright and powerful beam of light that is more intense than most LEDs on the market.
Push Button for Convenient Operation
Designed to keep out dust and other particles, the rubber, push-button tail cap is quick and easy to use with one hand. Depress the tail cap slightly for a momentary light, or click into the constant-on position. With a comfortable, tactile feel, the convenient push button is also stiff enough that it won't accidentally turn on in your handbag or pocket.
Durably Constructed for Use in Extreme Conditions
Machined from solid, aircraft-grade aluminum, the MicroStream is corrosion and water resistant, and features an unbreakable and scratch-resistant polycarbonate lens. Arriving with an unbreakable pocket clip, the MicroStream is ideal for use in automotive, hardware, law enforcement, security, sporting, and outdoor applications. It's been extensively field tested and drop-test verified above the industry standard of 6 feet.
The Streamlight MicroStream Penlight is backed by a manufacturer's limited lifetime warranty.
