Frequently Asked Questions

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

A: This flashlight emits UV light at 395–410nm, which falls in the near-UV / black light range. This wavelength is highly effective at causing fluorescent materials — such as dried pet stains, scorpion exoskeletons, currency security fibers, and UV-reactive dyes — to visibly glow, making detection fast and reliable even in total darkness.

Q: What batteries does the UV flashlight use, and are they included?

A: The flashlight is powered by a single 3.7V 14500 rechargeable lithium battery or a standard AA alkaline battery. Batteries are not included in the package. For the brightest UV output, we recommend a 14500 lithium cell.

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

A: Yes, when used responsibly. Avoid shining the UV beam directly into eyes (human or animal), as prolonged direct UV exposure is not recommended. Use the light to scan surfaces from a safe distance — the 50–100 m range means you can inspect areas without being directly over them. The IPX-4 waterproof body also means it's safe to wipe down with a damp cloth after use.

Q: Can I adjust the brightness or beam pattern?

A: Absolutely. The SK68 features adjustable zoom (slide the barrel to switch between flood and spot beam) and 2–4 dimmer/mode settings, so you can customize the output for close-up inspections or wide-area scanning.
