TUKO D15 365 nm UV flashlight 2 pack

Detection wavelength

This two-pack supplies 365 nm ultraviolet flashlights built for professional inspection tasks. The shorter wavelength reveals fluorescent agents, security markings and pet stains that longer UV lights miss. Each unit fits in a pocket and clips to a belt or bag for hands-free carry. Aluminium alloy construction handles daily use in workshops, vehicles or crime scenes.

Adjustable focus and hidden USB charging

A zoomable beam lets users widen the spot to scan a large surface or narrow it to pinpoint a leak or stain without bending or walking extra steps. The USB plug is concealed under the tail cap; unscrew and insert directly into any USB-A port such as a laptop or power bank. A red indicator lights when the cell needs recharging, preventing unexpected shutdowns during a job.

Practical limits of 365 nm UV

The 365 nm output is invisible to the naked eye, so the beam appears dimmer than 395 nm alternatives while delivering superior contrast for forensic and authentication work. Continuous runtime is limited to one hour per charge, making the lights suited to targeted inspections rather than extended area lighting. Bright ambient light reduces fluorescence visibility, so best results occur in darkened environments.
