365nm vs 395nm — why 365nm is the one you want

Cheap "UV" lights are 395nm, which is mostly visible violet light. You get a purple wash that drowns out the actual fluorescence you're trying to see — scorpions look dim, gem inclusions disappear, security threads barely register.

365nm is true ultraviolet — invisible to the human eye. Because the beam itself doesn't show up, the only thing you see is what genuinely fluoresces. Scorpions glow electric blue-green, currency security threads pop sharp, mineral fluorescence reads clean, and pet stains stand out with no purple haze fighting them.

If accuracy matters at all, 365nm is the correct choice — and that's what we sell.

What 365nm is good for

• Scorpion hunting — bright blue-green fluorescence in the field
• Minerals and gemstones — natural vs treated stones, epoxy fills, fluorescent specimens
• Leak detection — HVAC, automotive, and plumbing tracer dye
• Currency and document verification — embedded UV security threads
• Forensics and pet-stains — organic residue and biological fluorescence

Eye and skin safety

Never look directly into a 365nm beam, avoid prolonged skin exposure, and use UV-blocking eyewear when working close.
