NDT UV-A 500 Flashlight

The Lumirati® NDT UV-A 500 Narrow-beam Flashlight is a small-sized, lightweight inspection flashlight designed keeping mobility in the mind. The flashlight has a compact design, allowing inspectors much-needed portability. The flashlight housing is made up of corrosion-resistant, high-grade anodized aluminum.

Every Lumirati® NDT UV-A 500 Narrow-beam Flashlight is equipped with a Lumirati® Black Light Filter to reduce the output of wavelengths longer than 400 nm. Unlike mercury bulbs, the full power of the lamp can be reached instantly. The on/off switch is positioned on the backside of the flashlight for easier access.  The Lumirati® NDT UV-A 500 Standard-beam Flashlight runs on a 18650 Lithium-ion battery. We recommend using Lumirati® 18650 Lithium-ion Battery for safer operations.
