This Rechargeable UV Fluorescent Work Light uses a single 13 watt ultraviolet fluorescent bulb. The light from the ultraviolet fluorescent bulb emanates from both the tip of the light as a small spotlight and from the body as a floodlight. This design doubles the usage of this uniquely designed work light. The ultraviolet light is designed to be used in conjunction with leak detection die and has an effective detection range of approximately 2 feet. The electronic ballast provides instant, no-flicker cold weather starts. The handle has a natural ergonomic shape making it a pleasure to hold and use. Further adding to this light's hands-free functionality is the nylon tipped double hooks. The on/off switch is a single rocker style switch. This work light comes with 2 Dual-Capacity 7.2v Nickel Metal Hydride Battery providing approximately 8 hours of runtime (4 hours per battery) yet only requiring 2 hours to charge each of the batteries. Comes with the charger, the AC/DC Power Supply and a molded storage case.
