51 LED 395 nm UV torch

This aluminium 6063-T6 flashlight carries 51 UV LEDs emitting between 395 nm and 400 nm. It runs on three AA cells, not included, delivering a working voltage of 4.5 V. A centre-mounted button switch controls the light. The barrel measures 146 mm long with a 56 mm head and 35 mm tail.

6 to 8 hour runtime on three AA cells

At full output the light runs for six to eight hours before the cells need replacing. The 51 LED array covers a wide area for fluorescence inspection, leak detection or campsite marking. Output drops gradually as the alkaline cells drain, so very long searches may need fresh batteries.

Ordinary oxidation finish, pocketable barrel

The plain oxidation coating resists casual wear but is not a hard-anodised tactical finish. No lanyard loop or clip is mentioned, so a sheath or pocket is needed for carry. The 146 mm length fits most pouches, freeing belt space for other gear. No charger or rechargeable cells are included.

Questions about this item

Will the 395 nm UV output work with my older AA NiMH rechargeable cells?

The flashlight runs on three AA cells at 4.5 V; standard 1.2 V NiMH cells will power it, though run-time may be shorter than with alkaline batteries.

How can I confirm the 51 LEDs are emitting at 395–400 nm after I insert the batteries?

In a dark room the beam appears deep purple and makes fluorescent inks, security threads on banknotes or pet stains glow brightly, showing the correct wavelength.

The box lists only the aluminium 6063-T6 torch body — do I need to buy anything else to use it?

Three AA batteries are not included; purchase them separately. No charger, lanyard or filter is supplied.
