With a lightweight and compact body, the OPTI-LUX 365B greatly reduces user fatigue. It gets into tight, cramped places that larger lamps can’t. The flashlight has a coverage area of up to 2.5 inches (6.4 cm) in diameter at a distance of 15 inches (38.1 cm). This versatile unit produces an extremely uniform beam profile for both sample viewing and photography. Powered by one rechargeable lithium-ion battery (extra battery included in kit), the OPTI-LUX 365 provides four hours of continuous inspection time. The rugged, anodized aluminum lamp body minimizes corrosion and stands up to years of heavy use. This UV-A LED inspection flashlight comes complete with a lanyard, belt holster, two rechargeable batteries, smart 2-position charging cradle with AC and DC power cords, and UV-absorbing spectacles, all conveniently packaged in a padded carrying case
