Frequently Asked Questions

Q: What wavelength does this UV blacklight flashlight emit?

A: All models emit UV light in the 395–400 nm range (the 51 LED model at 390–395 nm), which is the optimal spectrum for detecting fluorescent stains, counterfeit markings, invisible inks, and causing scorpions to fluoresce visibly.

Q: What batteries does the UV flashlight require?

A: All models use 3×AAA standard alkaline batteries. Batteries are NOT included — you'll need to supply your own before use.

Q: Is this UV flashlight waterproof?

A: Yes. The flashlight features silicone O-ring seals for water resistance, making it suitable for use in damp environments or outdoor settings.

Q: Can this UV torch detect pet urine stains on carpet?

A: Absolutely. Dried pet urine contains phosphors that fluoresce brightly under 395–400 nm UV light, making hidden stains on carpets, rugs, mattresses, and upholstery clearly visible even in low-light conditions.
