Tracer's super-compact OPTI-Lite, No. TP-8620CS, is a cordless LED flashlight that reveals leaks in confined areas unreachable by larger, bulkier lamps. At 7-1/4" long and 5oz., the unit can easily be carried around in a pocket. It is powered by six LEDs, with light output comparable to a 50W lamp, making all fluorescent dyes glow brightly. It features a 100,000-hour LED life and an inspection range of up to 2' or more. The OPTI-Lite comes with fluorescence-enhancing glasses and is powered by 3 AA batteries (included).
