Streamlight 51045 Twin-Task 3C UV LED Flashlight 185 Lumens Black

The Streamlight Twin-Task 3C UV (51045) is a professional-grade, multi-mode LED flashlight designed for law enforcement, forensic science, automotive diagnostics, HVAC inspection, and industrial applications. It combines a powerful white C4® LED with six 390nm ultraviolet LEDs into a single durable tool, giving users versatile lighting options for virtually any task.

Three Lighting Modes:

• White Light Mode: C4® LED with textured reflector delivers 185 lumens, 3,730 candela peak beam intensity, and a 27-hour runtime — providing an even beam with a piercing hotspot for distance
• High UV Mode (6 LEDs): All six 390nm UV LEDs active at 40mW output for maximum ultraviolet coverage — 63-hour runtime
• Low UV Mode (3 LEDs): Three 390nm UV LEDs for extended runtime up to 81 hours

The 390nm UV output is ideal for detecting fraudulent documents, identifying engine and HVAC refrigerant leaks, and a wide range of forensic and scientific applications. A simple push-button head switch cycles through all three modes plus off for easy one-handed operation.
