Streamlight 66134 Stylus Pro 350-Lumen Penlight with Holster, Black

The Stylus Pro USB 350-Lumen Penlight is a slim, pocketable illumination tool built for professionals who frequently work in cramped or dark spaces. Its lightweight aluminum form fits neatly into chest pockets, equipment bags, or the included holster, making it a reliable everyday light for technicians, first responders, and medical personnel.

Equipped with a bright white LED, the penlight provides two distinct output levels to match your task. You get up to 1.5 hours of continuous runtime on the high setting and up to 3.5 hours on the low setting. Recharging is handled directly through a built-in port, taking roughly 2.5 hours with the supplied USB to micro-USB cable.

Durability is focused on real-world job hazards. The body features an IPX4 water-resistant rating and has been tested to survive 1-meter impacts. To keep dust and moisture from damaging the electronics, a sliding metal sleeve physically covers and protects the charging port when it is not plugged into a power source.

Keep in mind that continuous use is limited to 1.5 hours on high output, so long shifts may require recharging or switching to the lower power setting. The unit also relies on a micro-USB connector rather than modern USB-C.

Verdict: This penlight is an excellent, compact choice for technicians, inspectors, and medical workers needing dependable close-up visibility. Its fast charging, solid water resistance, and rugged sliding port cover make it a practical daily carry tool.
