DARKBEAM 365nm Rechargeable UV Flashlight

A compact light for fluorescence checks

The DARKBEAM 365nm UV flashlight illuminates materials that react to ultraviolet light. It can help with close inspection of residues, minerals and fluorescent markings during a location survey.

What to expect

The linked listing describes a rechargeable handheld UV light with aluminum construction and adjustable focus. Its 365nm wavelength can produce fluorescence with less visible purple light than many 395nm blacklights. Visible brightness alone is not a useful measure of UV output.

Interpret what you see carefully

A glowing mark does not identify its cause. Detergents, fibers, coatings and other ordinary materials can fluoresce. Photograph a surface under normal light as well as UV, and compare the two views before drawing conclusions.

This is an inspection accessory, not a spirit detector, medical diagnostic lamp or guaranteed way to identify an infestation. Keep a normal white flashlight for navigating the location.

Before using the light

Follow the manufacturer’s UV precautions, avoid direct exposure to eyes and prolonged skin exposure, and check the supplied charging instructions. Confirm the current package contents with the retailer.
