350-Lumen Stylus Pro USB Rechargeable Pen Light - Black

Our review of the 350-Lumen Stylus Pro USB pen light finds it best suited to technicians, medical staff, and law enforcement officers who need a compact, dependable light for close-up inspection. The single biggest reason to buy is simple: it packs a powerful, steady 350-lumen white LED into an ultra-slim, pocketable body that stays ready thanks to an internal rechargeable battery and a protected USB port.

Key Features

• Ultra-slim design: The lightweight, slim body clips easily into pockets, tool kits, or medical pouches for everyday carry on job sites.
• Reliable white LED output: The bright, focused beam provides steady light for inspecting confined spaces and detailed work under low light.
• Rechargeable power: The integrated rechargeable battery charges via USB in about 2.5 hours, avoiding repeated battery purchases.
• Long runtime: Run time reaches about 1.5 hours on high and about 3.5 hours on low, covering short to moderate tasks without interruption.
• Built Streamlight tough: IPX4 water resistance and 1 m impact testing add real durability for field and industrial use.
• Protected charging port: A sliding metal sleeve shields the micro-USB port from dirt and moisture while keeping the light slim.

Who It's For

The Stylus Pro is ideal for first responders, inspectors, and technicians who need a bright, focused pen light that fits a shirt pocket or tool pouch and can be recharged between shifts. Medical staff who use penlights for exams will also appreciate the compact form and steady white output.

Users who require all-night runtime for continuous illumination or who prefer USB-C charging should consider larger handheld lights or models with different charging ports, since this pen light uses micro-USB and is optimized for close-up tasks rather than extended continuous use.
