Streamlight
Streamlight Micro Stream USB
Thirty-four grams. That's the weight of a lamp you have no reason to leave at home - and that's the whole point of the Micro Stream.
The pen format
98 mm long. It fits in your palm, clips into a shirt pocket, and you forget it's there. CNC machined body in matte black anodized aluminum.
The two modes
High: 250 lm, range 68 m, battery life 1.5 h
Low: 50 lm, range 31 m, battery life 3.5 h
The 50 lumens of the low mode are sufficient for most daily uses: finding a lock, reading under a hood, going down stairs. The 250 lumens are there for when you really need to see far.
USB Rechargeable
Integrated Li-Ion battery, recharged via USB cable. No more batteries to buy - but also a battery that needs to be remembered to recharge.
The charge indicator is integrated into the rear button: red during charging, green once completed.
The charging port is protected
A metallic sleeve at the front protects the port from moisture and dust. This is the usual weak point of rechargeable lamps, and it is addressed here.
Water resistance
IPX4: resistant to water splashes, not immersion. Shock resistance up to 1 meter. Multi-coated anti-scratch lens.
