OPTI-LUX™ 365 UV-A LED Inspection Lamp

Affordable, Super-Compact, UV-A LED Flashlights Designed Specifically for NDT!

OPTI-LUX 365 Series inspection flashlights feature a powerful UV-A (365 nm) LED light source coupled with a rugged anodized lamp body. Lightweight and compact, they reduce user fatigue while providing an extremely uniform beam profile that surpasses those of more expensive lamps. Available in four models to suit your specific NDT needs: high-intensity or standard-intensity versions, each with or without an internal black light filter. All flashlights come with a certificate of compliance for both wavelength and output measurements.
