A: The 395nm wavelength is ideal for everyday UV tasks such as checking currency security strips, inspecting UV-reactive glasses coatings, and detecting pet urine stains on carpets and upholstery. The 365nm wavelength produces a deeper, purer UV output that is better suited for detecting fluorescent agents in products, authenticating banknotes (USD, EUR, and others), and verifying anti-blue light lenses. Both wavelengths are available on this compact torch, giving you maximum versatility.
