Average Reviews:
(More customer reviews)I own many flashlights, and this is by far my favorite using a 1xAAA format. The brightness is exceptional for the size and weight. I believe the 20-lumen rating is accurate, by comparison with many other lights I own. I also own the larger 2xAAA version of this light (Streamlight Stylus Pro), and the microstream is almost identically bright. Of course, the 2xAAA version has longer battery life, by more than a factor of 2 because of circuit efficiency and battery-capacity variance with discharge rate.
The switch type is my favored "forward" clicky, which means you can push it slightly to get a momentary-on function. Some other lights use a "reverse" clicky, which doesn't turn on until you click and release.
The one thing I dislike about both of these lights is that the pocket clip rotates with the threaded end cap, badly scratching the finish when you remove the cap to replace the battery. You can avoid this by placing a piece of cloth between the clip and flashlight body before turning the cap, but you have to think of this before first disassembly or it's too late.
Also, the clip exerts enough sideways pressure on the light body that you must be very careful to avoid cross-threading when you reinstall the cap onto the body.

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 LightAn 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 IlluminationWith 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 ConditionsMachined 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.
