Frequently Asked Questions

Q: What is the UV wavelength of this black light flashlight, and why does it matter?

A: This UV flashlight operates at 395–400 nanometers, which falls in the near-UV/violet range. This wavelength is highly effective at causing fluorescent materials — such as pet urine, security ink markings, and certain minerals — to glow visibly, making it ideal for both household and professional detection tasks.

Q: Do batteries come included with the UV flashlight?

A: No, batteries are not included. All three models (9 LED, 12 LED, and 21 LED) require 3× AAA batteries, which are widely available and easy to source at any grocery or hardware store.

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

A: Yes, when used as directed. Avoid shining the UV light directly into eyes (human or animal). For safe usage, point the light toward surfaces rather than at people or animals, and keep out of reach of young children when not in use.

Q: Can this flashlight cure UV gel nail polish?

A: The 395–400nm UV light emitted by this torch is compatible with many UV-curable gel nail products. However, curing times may vary depending on the specific gel formula and LED count selected. The 21-LED model offers the most power output for this use case.
