Build and Design

The Fenix LD02 V2.0 features a stainless steel head and tail, while the body is constructed from high-strength aluminum alloy. This ensures the flashlight can endure daily wear and tear while providing a sleek and professional appearance. The build is compact and lightweight, allowing easy handling and convenient storage.
