ULTRAVIOLET LED PENLIGHT — 395 NM, IPX4, 2.75 HR RUNTIME

The Railhead RH-UV2000 is a small, light ultraviolet pen light for finding what a work light can't. Under its 395 nm UV, dye-traced fluids fluoresce, and a hydraulic weep or coolant seep that was invisible becomes obvious — for HVAC and refrigeration, automotive and fleet diagnostics, aviation maintenance, and forensic or document inspection. The aircraft-grade aluminum body with impact-resistant polycarbonate and rubber drop bumper is drop-tested to 6.6 ft (2 m) and sealed to IPX4. The RH-UV2000 delivers 325 mW of regulated output that holds steady across battery life, with up to 2.75 hours of continuous run time. Simple On / Off operation through a positive mechanical switch, a metal clip for carry, and a purple UV cap so it's unmistakable in a bag. Runs on (2) AAA alkaline batteries (not included)
