Hetai Tech 365nm/395nm UV Flashlight Zoomable AA/14500

SKU CH-FKA9-PHNSJ

A zoomable UV torch emitting 365nm and 395nm wavelengths for fluorescence detection, powered by one AA or 14500 cell

  • Type6 VOLT
  • Dual 365nm and 395nm wavelengths reveal different fluorescent materials
  • Zoomable focus adjusts beam from wide scan to concentrated spot
  • Powered by common AA or 3.7V 14500 cells for easy replacement
  • Rugged black-oxidised aluminium body with orange-peel reflector resists knocks
  • Tail push switch and lanyard keep light ready for detection work

Dual-Wavelength UV Inspection Tool

The Hetai Tech UV flashlight emits selectable 365nm and 395nm wavelengths for fluorescent agent detection. It runs on a single 3.7V 14500 or AA battery, making it a portable option for currency verification, forensic work, and night fishing. A zoomable focus and single-mode tail switch keep operation simple in the field.

Upgrade From Basic UV Lights

This unit replaces single-wavelength torches that only cover one detection range. The dual 365nm/395nm output lets users switch between shorter and longer UV bands to reveal different fluorescent responses in documents, stains, or fishing floats. The jump is worth it when one tool must handle both high-precision inspection and general-purpose UV scanning.

Limits of 14500/AA Power

The light draws from a single 14500 or AA cell, so runtime and peak output are constrained by that cell's capacity and discharge rate. Zoom mechanics and the integrated reflector cup concentrate the beam but cannot overcome the energy ceiling of a small primary or rechargeable battery. Users needing sustained high-intensity UV for extended periods will find the format limiting.

Questions about this item

What size battery does the Hetai Tech UV flashlight take?

It accepts one 3.7 V 14500 rechargeable cell or a standard AA battery.

How do I turn the flashlight on and what is the common mistake?

Press the tail-cap push switch once; the common mistake is forgetting to tighten the tail cap fully so the circuit does not complete.

When should I replace the battery in this UV torch?

Replace or recharge the cell when the 365 nm or 395 nm beam noticeably dims or fails to make fluorescent material glow blue.
