A: The 395nm UV pen flashlight is excellent for revealing pet urine stains from cats and dogs, spotting scorpions in dark areas, authenticating banknotes and ID documents, checking for fluorescent residues or leaks, and identifying certain gemstones and minerals. The UV wavelength causes these substances to fluoresce, making them clearly visible in low-light conditions.

A: Yes, it has a daily-life waterproof rating, meaning it can withstand splashes and light rain during everyday use. It is not designed for submersion or heavy rain exposure, so avoid prolonged water contact.

Q: Can I use both UV and white light modes on the same unit?

A: This listing covers two variants — one configured for UV (395nm) output and one for white light output. Each pen flashlight features its respective light mode with High / Medium / Low brightness settings. Check your selected variant to confirm which mode it operates in.
