Streamlight MicroStream USB Review: Pocket Light Done?
A pocket flashlight under four inches long with a USB rechargeable battery and a clip that fits a cap brim. The light he will actually carry.
Yes, for a man who is always looking for a flashlight in the junk drawer. It is small enough to clip in a pocket and bright enough for a driveway [1]. Skip it if he wants a big lantern for camp.

Pros and cons
- Short runtime on high [1]
- Not a camp lantern
- Small enough to lose
Small light, real brightness
The MicroStream gives 250 lumens on high with a 68 meter beam, and 50 lumens on low [1]. That is plenty for a dark driveway, a breaker box or an engine bay.
It measures under four inches and slips into a jeans pocket without notice [1].
The aluminum and polycarbonate body keeps it light, so it adds almost nothing to a pocket already holding keys and a phone [1]. That is the difference between a flashlight he owns and one he carries.
Charging and the hat clip
An internal lithium-ion battery charges from the included USB cable, with a charge status indicator [1]. No hunting for batteries.
The removable clip fits a cap brim, so the light points wherever he looks while both hands work [1].
Charge it once a week or after any long job and it is always ready. The status indicator shows when it is full [1].
Two brightness modes keep things simple: a strong beam for finding something in the dark and a lower one for reading a label or saving the battery.
Runtime limits
High mode runs about 1.5 hours, low about 3.5 [1]. That is fine for jobs and dog walks, but not an all night campsite light.
It is also small enough to disappear into a couch. A bright lanyard helps.
The beam is a focused spot rather than a wide flood, which is ideal for looking into an engine or under a sink but less so for lighting a whole room.
Keep the cable with it in a drawer, since it is easy to misplace.
Built to be dropped
It is IPX4 water resistant and impact tested to one meter [1]. Rain and a drop on the driveway will not kill it.
From this guide, pair it with the Klein multi-bit screwdriver for a small fix-it kit, or the Opinel for camping.
It suits a mechanic, an electrician, a dog walker or simply the man of the house who gets sent to the basement when the breaker trips. Put it in the stocking charged and ready to use.
