Streamlight Stylus Pro 66118 Penlight - 100 Lumen C4 LED Black

The Streamlight Stylus Pro 66118 delivers professional-grade illumination in a compact penlight format, producing 100 lumens of bright white light from its advanced C4 LED technology. This black anodized aluminum flashlight provides reliable hands-free lighting for detailed inspections, tactical operations, and everyday carry applications.

What Makes This Different

Unlike standard penlights that produce dim, yellowish light, the Stylus Pro features Streamlight's C4 LED technology that generates 100 lumens of crisp white light with exceptional beam quality. The machined aluminum construction with black anodized finish resists corrosion and impact damage far better than plastic alternatives. At just 5.3 inches long and weighing 1.6 ounces with batteries, it maintains professional performance without the bulk of larger tactical lights.

Key Features

• 100-lumen C4 LED produces bright white light with 11,684 candela peak beam intensity
