COSMOING FL16-UV.1 395 nm UV Penlight

The COSMOING FL16-UV.1 is a 395 nm ultraviolet flashlight built in a compact pen form factor. It uses a 3 W LED powered by two AAA batteries to reveal invisible stains, counterfeit marks and fluorescent minerals. The aluminium body measures 5.43 inches long and weighs 0.07 pounds. An IP65 rating protects the internals from dust and water jets.

Suits inspection, forensics and hobby use

This light suits pet owners locating urine stains, travellers checking hotel hygiene and professionals verifying documents or currency. The zoomable beam lets users switch between wide-area scanning and focused spot checks. It is not for buyers who need a high-output flood for large-room illumination or a hands-free headlamp for extended work sessions.

Steady output for 300 minutes

Under continuous use the 3 W emitter runs for approximately 300 minutes on a fresh pair of AAA cells before output drops noticeably. The aluminium housing conducts heat away from the LED, keeping surface temperature comfortable during long scans. Performance remains consistent across the rated runtime rather than fading after a short burst.

Questions about this item

What type and quantity of batteries must I supply to power the FL16-UV.1?

The flashlight requires two AAA batteries, which are not included in the package.

Will the IP65-rated body survive the same wet conditions as my older IP54 gear?

Yes, IP65 provides a higher level of water resistance than IP54, so it handles heavier rain or splashes without issue.

How can I confirm the 395 nm UV output is active after inserting the batteries?

Shine the beam on a white sheet of paper or a banknote; the UV light will cause optical brighteners or security fibers to fluoresce visibly.
