Streamlight Stylus Pro® USB LED Penlight Flashlight

The Light That's Always There When You Need It Most

You've been in that moment — reaching for your light in the middle of a procedure, an inspection, or a dark parking garage, and it's dead. Or worse, it's not there at all. The Streamlight Stylus Pro USB exists to make sure that never happens again.

Slim enough to live in your shirt pocket every single day. Bright enough — 350 lumens, 109-meter beam — to handle real work, not just fumbling around in a drawer. And because it charges via any USB source in 2.5 hours, you're never hunting for batteries at the wrong moment.

This is the penlight that professionals at Lumex Flashlights reach for. And once it's clipped to your pocket, you'll wonder how you ever worked without it.

Two Modes. One Switch. Total Control.

A push-button tail switch gives you momentary or constant-on operation — no menus, no cycling through modes you don't need. High mode: 350 lumens for 1.5 hours. Low mode: 90 lumens for 3.5 hours when you need to stretch the runtime. A charge indicator LED keeps you honest — red means charging, green means go.

That sliding metal sleeve protecting the USB port? It's the kind of detail that tells you this light was designed by people who actually use tools, not just sell them.

Built to Last. Built to Carry.

Anodized machined aluminum construction. Gasket-sealed glass lens. IPX4 water-resistant. Impact-tested to 1 meter. At 5.95" and just 1.8 oz, it disappears in your pocket until the moment it matters. Available in 5 colors — because the best EDC light is the one you'll actually carry.
