Frequently Asked Questions

Q: What wavelength does this UV flashlight emit and why does it matter?

A: This UV flashlight emits at 395–400nm, which sits in the near-UV (UV-A) range. This wavelength is highly effective at causing fluorescent materials — such as dried biological stains, fluorescent security inks on banknotes, and certain minerals — to visibly glow, making detection quick and easy without damaging surfaces.

Q: Which LED count should I choose — 21, 51, or 100?

A: The 21 LED model is compact and ideal for everyday carry, spot-checking small areas, and document verification. The 51 LED model offers a wider beam and longer bulb life (up to 100,000 hours), making it great for home inspections and pet stain detection across larger areas. The 100 LED model provides the broadest, most powerful UV coverage, best suited for thorough room inspections and professional use.

Q: Are batteries included with the UV flashlight?

A: No, batteries are not included. The 21 LED model requires 3×AAA batteries, the 51 LED model requires 3×AA batteries, and the 100 LED model requires 6×AA batteries. Standard alkaline batteries are recommended for optimal performance and runtime.

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

A: Yes, when used responsibly. Avoid shining the UV beam directly into eyes, as UV-A light can be uncomfortable with prolonged direct exposure. Always point the beam at surfaces rather than at people or animals. The flashlight is designed as a detection tool for surfaces and materials, not for direct eye or skin exposure.

Q: Can this flashlight detect all types of pet stains?

A: This UV flashlight is highly effective at locating dried pet urine stains on carpets, rugs, upholstery, and hard floors, as the urine's organic compounds fluoresce strongly under 395nm UV light. Fresh, wet stains may be less visible under UV than fully dried ones. It works best in a darkened room for maximum contrast.
