## Description

desertcart.com Compact and lightweight, the Streamlight MicroStream is a portable penlight with a super-bright, high-flux LED that lasts up to 30,000 hours.

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.

Review: Perfect daily carry light - This is the greatest pocket flashlight ever made. I have destroyed 3 of these lights over the past 5ish years of carrying them every day and am incredibly impressed by how robust they are. This is really a difficult thing to destroy, and every one has partially still worked despite my abuse. Reverse clip is perfect for use on a hat, which I always use in place of a headlamp which I find bulky and restrictive, there are no modes to deal with, just a pleasant, useful light level that isn't too bright for up close work in tight aircraft service compartments where I often find this level of light most useful. One AAA battery, easy to carry extras, and a good few hours of output per battery. I own a stinger 2020 and this light, and between work and home I never find myself asking for anything else. These lights really aren't that fancy or crazy like many of the Chinese brands with high output and hella modes, but damnit they just work

## Questions & Answers

**Q: New specs on Streamlight website is 45 lumens, is this 45 or the older 35 lumens?**
A: March 2022, it's 45 lumens.

**Q: Is this the newest version with 35 lumens?**
A: Bought my second Microstream on April 30, 2016. It was the 35 Lumen version.

**Q: can i buy a replacement end cap for this light? i bought it and love this light but the on switch is already worn out and the light goes off.**
A: Amazon sells the end cap switch (part number 660023) that fits both the MicroStream (uses 1 AAA battery) as well as the Stylus Pro (uses 2 AAA batteries). Right now it is $6.96 + tax. I was about to order a new switch when I thought I would see if they are usable in either light. The alkaline batteries that came with my Stylus Pro leaked and damaged the switch. Now I will be using NiMH batteries in the Stylus Pro like the one I am using in my MicroStream.

**Q: does it have hat clip**
A: I received mine this week, October 2020 and it is 250 lumen and has a combination hat/pocket clip.  Very nice light.

Great surpresa! It is small and has a potent bright light and several sets to use! Good material! Cheap to recharge!!

### ⭐⭐⭐⭐⭐ Excellent Little Flashlight
*by N***R on September 22, 2025*

It's bright and the battery lasts plenty long; it's durable, and I don't worry about it's getting damaged. I have a canvas leatherman pouch I keep on my belt; it has loops on either side of the the leatherman tool holder itself. In one loop, I keep a ratcheting extender. In the other loop, I keep this flashlight. I can leave it in the loop and press the button when I need to illuminate things I can point at by moving the holder slightly. This happens fairly frequently as I help my elderly parents up and down the outside stairs and it's helpful to be able to light them up. It is very nice to have access to a bright light source all the time, and this flashlight makes that easy.
