The Streamlight Stylus Pro USB is a sleek, professional-grade penlight designed for high performance in a compact form factor. It delivers a powerful 350-lumen beam with a 109-meter reach on its high setting, while the 90-lumen low mode extends runtime for close-up tasks. Constructed from durable Type II Military Spec anodized aluminum, the 1.80-ounce light is both water-resistant and highly resistant to abrasion. The integrated lithium-ion battery is easily recharged via USB, eliminating the need for disposable cells. Featuring a tactical tail cap switch and a 0.63-inch body diameter, it fits comfortably in a pocket or the included nylon holster. This versatile tool is ideal for technical inspections, maintenance, and everyday carry applications.
