NDT UV-A 650 Headlight

The Lumirati® NDT UV-A 650 Standard-beam Headlight is a small-sized, lightweight inspection flashlight designed keeping mobility in the mind. The Headlight has an intelligent design, allowing inspectors to have both hands free during an inspection. The flashlight housing is made up of corrosion resistant, high-grade anodized aluminum and has the arrangement to adjust the beam angle.

Every Lumirati® NDT UV-A 650 Standard-beam Headlight 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 Headlight for easier access.  The Lumirati® NDT UV-A 650 Standard-beam Headlight runs on a 18650 Lithium-ion battery. We recommend using Lumirati® 18650 Lithium-ion Battery for safer operations.
