SOLIDLINE ST4 UV – Precision Lighting with UV Detection in a Sleek Penlight Design

The SOLIDLINE ST4 UV is a compact and high-performance penlight that combines precision white light with versatile UV illumination, making it an essential tool for inspection professionals, field technicians, law enforcement, and anyone needing a portable dual-light solution. Designed by Ledlenser with signature German engineering, this penlight offers functionality far beyond its size.

Equipped with a Power LED delivering up to 180 lumens and an additional UV LED (365nm), the ST4 UV allows users to switch seamlessly between bright general illumination and ultraviolet light for specialized tasks. From banknote verification and document inspection to leak detection and cleanliness checks, the UV function greatly expands its utility.

The UV light mode features both constant-on and slow-blink settings, enhancing the visibility of fluorescent elements by improving contrast against ambient surfaces—ideal for precision tasks in low-light conditions. All functions are controlled via a tail-mounted clicky switch for intuitive single-hand operation.

Constructed from aerospace-grade aluminum, the ST4 UV is lightweight yet rugged, designed to withstand daily wear and tear in demanding work environments. The metal pocket clip ensures secure carry in your shirt, vest, or toolkit, making it perfect for EDC (everyday carry) professionals.

Powered by two standard AAA batteries, the ST4 UV delivers up to 30 hours of runtime, ensuring long-lasting performance without the need for charging. Its IP54 water resistance rating protects against dust and light water spray, making it a reliable companion indoors or out.
