Frequently Asked Questions
Q: What batteries does the UV pen flashlight require?
A: The UV pen flashlight runs on 2 × AAA batteries, which are not included in the package. Simply insert standard AAA batteries to get started.
Q: Is this UV flashlight safe to use around people and pets?
A: The 395nm UV wavelength used in this torch is in the near-UV range. Avoid pointing it directly at eyes or skin for extended periods. It is designed for brief, targeted inspection tasks and is safe for incidental use when handled responsibly.
Q: Can this flashlight detect all types of pet stains?
A: The 395nm UV beam causes many biological residues — including pet urine — to fluoresce and glow under ultraviolet light, making them visible even after cleaning. Results may vary depending on the surface material and cleaning products used.
Q: What does IPX4 waterproof mean for this torch?
A: IPX4 means the flashlight is rated to withstand water splashing from any direction, making it suitable for use in rain or around water splashes. It is not designed for submersion or underwater use.
Q: How does this UV torch help with counterfeit banknote detection?
A: Genuine banknotes contain UV-reactive security features — such as fluorescent threads and markings — that glow brightly under 395nm ultraviolet light. Counterfeit notes typically lack these features, making it easy to spot the difference instantly.
