Tracerline’s Opti-Lux 365 is an LED leak-detection flashlight that provides pure ultraviolet light for better fluorescent dye response.

The light is designed for use on A/C and fluid systems. The Opti-Lux 365 produces a bright light for quicker leak detection and reduced diagnostic time. It's more than twice as powerful as most corded high-intensity UV lamps, says Tracerline, and can also pinpoint high-mileage diesel engine oil leaks.

The Opti-Lux 365 is also designed with a compact and lightweight form factor. It has an inspection range of 25 feet or more and is powered by a single, rechargeable lithium-ion battery that can provide 4 hours of continuous use between charges. The anodized aluminum lamp body is made to resist corrosion and is durable enough for heavy shop use.

The kit comes in a padded carrying case that includes a lanyard, belt holster, two rechargeable batteries, a smart-charging cradle with AC power cord and UV-absorbing spectacles.
