JacobsParts FLT-C 365nm 5W UV LED Flashlight Adjustable Focus

365 nm UV Flashlight for Inspection

The JacobsParts FLT-C emits a 365 nm wavelength from a 5 W UV LED chip, producing near-pure ultraviolet output that makes fluorescent materials stand out without a violet glow. Its adjustable focus lets users narrow or widen the beam for counterfeit detection, document verification, photography or bodily fluid identification. The aluminium body weighs 2.93 ounces and measures 114 by 47 mm.

365 nm Wavelength Determines Suitability

A 365 nm source stays well below the 400 nm visible threshold, so fluorescence appears cleaner and colours more vivid than with 395 nm lights that bleed violet into the scene. Choose this wavelength when the task demands maximum contrast on security features, inks or stains rather than general-purpose UV illumination.

Runs on One AA Cell

Power comes from a single AA battery, which is not included, keeping the light compact at 4.5 by 1.9 inches and ready for field use with a belt clip for quick access. No charger, cable or additional cells ship with the unit, so buyers must supply their own power source before the first inspection job.
