Compact UV penlight for targeted inspection

The Hetai Tech YT-P721UV is a 125 mm aluminium penlight that emits at 365 nm, 380 nm and 395 nm. It runs on two AAA cells and weighs 18 g without batteries. The narrow beam is designed for close-range tasks such as glue curing, invisible-ink detection and document verification rather than wide-area illumination.

Step up from single-wavelength lights

A single-wavelength UV torch only reveals a limited range of fluorescence. Adding 365 nm and 380 nm extends detection to currency security features, fingerprint residues and art-forgery markers that 395 nm alone misses. The upgrade is worth it when one tool must cover forensic, authentication and hobbyist checks without carrying multiple lights.

Headroom for small-spot work, not broad floods

The 0.5 W LED comfortably cures small adhesive spots, validates banknotes and highlights pet stains on fabric. It runs out of reach when a user needs to light up a whole room, scan large surfaces at a distance or cure broad areas quickly; those jobs demand a higher-output model such as the B107UV or P72XUV series.

Questions about this item

What is the diameter of the aluminium body?

The penlight measures 13 mm across its aluminium alloy body.

Which end cap do I unscrew to load the batteries?

Unscrew the tail cap only — the head section must stay sealed — and insert two AAA cells with the positive ends pointing toward the LED.

How long will the 0.5 W UV LED last before it needs replacing?

The LED is rated for tens of thousands of hours, so under normal use it will not require replacement during the penlight's service life.
