The Tracerline Optimax 365 is a cordless, rechargeable ultraviolet leak detection flashlight featuring ultra-high-flux LED technology.

This high-intensity UV lamp works with truck systems and fluorescent dyes, including yellow dyes that can be difficult to light up. It easily pinpoints oil leaks in diesel engines, even when the oil is dirty.

The Optimax 365 is lightweight and compact with a weight of 11.8 ounces and inspection range of 25 feet. The flashlight has a corrosion-resistant, anodized aluminum lamp body, made to stand up to years of heavy shop use. 

Powered by a rechargeable NiMH battery, it provides 90 minutes of continuous inspection time between charges. The LED lifetime is 100,000 hours.

The Optimax 365 comes with UV-absorbing spectacles, a belt holster and smart AC and DC battery chargers contained in a padded carrying case. The AC charger is available in 120-volt, 230-volt, 240-volt or 100-volt versions.
