Review: Streamlight Microstream USB

I’ll spoil this review right up front. I really, really like my Streamlight Microstream USB.

Overview

The Microstream USB is an extremely compact LED light. It features a tail switch, a two way pocket clip (that is removable and replaceable), and two output settings (250 lumens for 1.5 hours and 50 lumens for 3.5 hours). This light is USB rechargable via a USB-C cord (included). It is less than 4″ long, barely wider than a AAA battery, and weighs a little more than 1 ounce.

The Microstream USB is available in a number of anodized colors but I recommend the FDE version because it is the only one that gives you the high output mode on the first click. The other colors (Black, Blue, Red) activate the 50 lumen mode on the first click.

Observations from Use

I normally prefer single output lights for EDC but the Microstream USB gets a pass. Streamlight designed it so that you could only access the 50 lumen low mode with a very fast double click. You can execute typical low light techniques without ever dropping into the 50 lumen mode. The user interface is dead simple and well designed.

The power to weight ratio on this light is incredible. It is so small and so lightweight that you will never leave it at home. It still has large light features like 250 lumen output and a tail switch in spite of that small size.

I typically carry a USB backup battery both at the office and on the trail. That makes it easy to keep this light up and running no matter where I am.

The light is recharged by sliding the bezel up to reveal the USB-C port and a small charge indicating LED (red for charging, green for charged). This sliding collar is o-ring sealed and it seams to do a good job given that my light has been through the wash with no ill effects. Still, this is the source of my major criticism of the light. I wish that this was sliding collar was threaded so that it had to be screwed down over the o-ring. This would make it even less likely to have water ingress. As it stands now, the user will have to keep a sharp eye on the o-ring to ensure that it is in good shape.

Wrap Up

This light is a tiny power house. I have larger lights with more output that I can can carry but this light is so small, lightweight, useful, and cheap to operate that I often carry it as a backup or even my primary light. It’s affordable too (less than $30)!

Have I said that I really, really like this light?

I had trouble finding the FDE anodized version when I bought mine last year. Now they are much easier to find. I purchased mine at Amazon who happened to be one the only places that had them in stock at the time: Streamlight Microstream USB on Amazon

    Matt, I’d love to hear your reco on the USB backup battery(s) you use. I am in the market.

      There are two from Anker that I really like (and I’ve gone through a handful from other brands that I don’t like). I should do a post on these eventually. They have saved my bacon more times than I can count.

      I use this one for travel because it serves as my wall wart too: https://amzn.to/2GufMyl

      This larger one is what I typically carry for overnighters or longer: https://amzn.to/2Vp3PU4
