Frequently Asked Questions

Q: What is the 395nm UV flashlight best used for?

A: The 395nm wavelength is ideal for a broad range of fluorescence-detection tasks. Common uses include spotting pet stains (urine, saliva) on carpets and furniture, verifying banknote security features, authenticating stamps and documents, inspecting fluorescent anti-counterfeit seals, and checking the authenticity of amber and gemstones. The 395nm range balances strong fluorescence triggering with a visible enough beam to navigate during inspection.

Q: Does the UV flashlight come with batteries?

A: No — batteries are not included. The flashlight requires 2 × AAA batteries, which are widely available. Simply insert them and use the tail-cover push switch to turn the light on or off.

Q: Is this UV flashlight waterproof?

A: Yes. It carries an IPX4 waterproof rating, meaning it is splash-resistant from any direction. It is not designed for submersion, but it will handle splashes and light rain without issue — making it durable for both indoor and outdoor inspection use.

Q: Is this UV light safe to use around pets and children?

A: As with any UV light source, avoid shining it directly into eyes. For routine surface inspection tasks (scanning floors, upholstery, or documents), keep the beam pointed at surfaces rather than at people or animals. Brief, incidental exposure is not considered harmful, but always exercise caution and keep the light pointed away from faces.
