The OPTI-LUX 365 is extremely compact and lightweight. With its powerful UV LED, the flashlight has an inspection range of 25 feet (7.6 m) or more. Powered by one rechargeable lithium-ion battery (extra battery included in kit), it provides 4 hours of continuous inspection between charges. The rugged, anodized aluminum lamp body reduces corrosion and stands up to years of heavy use. More than twice as powerful as most corded, high-intensity UV lamps, it works with Spectroline Aero-Brite universal fluorescent dye, producing a brilliant glow that makes all leaks easier to locate. Together, they pinpoint even the most elusive leaks the first time and every time. The flashlight comes complete with a lanyard, belt holster, two rechargeable batteries, smart charging cradle with AC power cord and UV-absorbing spectacles, all conveniently packaged in a padded carrying case.
