Streamlight MicroStream 45-Lumen Pocket Flashlight with AAA Battery Included

Small, mighty illumination for everyday tasks

Engineered for true everyday carry, the Streamlight MicroStream packs a surprising amount of light into a pocket-sized form. Weighing just 1.04 ounces, it slips into a pocket, purse, or tool bag with ease. The included AAA alkaline battery powers a 1/2-watt LED that delivers a focused beam at 20 lumens, ideal for close-up tasks and quick checks. With a runtime of about 1.5 hours, this compact light is ready when you need it most, without adding bulk or weight. The push-button tail cap supports reliable one-handed operation, letting you switch between momentary bursts and steady, hands-free illumination as your task requires.

Rugged, durable build for real-world use

Durability is built into the MicroStream’s DNA. The housing is machined from solid aircraft-grade aluminum with Type II MIL-SPEC anodizing, delivering abrasion and corrosion resistance that stands up to daily wear and harsh environments. The lens is a virtually unbreakable polycarbonate, scratch-resistant to keep your beam clear. A sturdy pocket clip keeps the light accessible, whether clipped to a jacket, hat brim, or bag strap. The design is water-resistant and has been drop-tested beyond standard expectations, so it can handle the occasional splash or drop.

Everyday use cases

Beyond its hardware, the MicroStream shines in real-world situations. It’s ideal for auto repairs in low light, searching for small parts in a toolbox, camping tasks at night, or locating a switch in a dark room. The compact size makes it discreet in professional settings, while its brightness and long LED life offer reliable performance over time. When you’re ready for portable lighting that’s easy to carry, clip on, and use with one hand, the MicroStream presents a practical option.
