  • Patent number: 6318884
    Abstract: A worklight string employing compact fluorescent lamps is suitable to be hung in a work area, such as in a building under construction. The worklight string has a power cord and a multiplicity of sockets, e.g., up to thirty or more, at intervals along the power cord. For each socket there is a compact fluorescent lamp of the type that has a standard Edison screw-in medium base. Each compact fluorescent lamp has a plastic globe covering its fluorescent tube. Because the fluorescent lamp is more efficient, three to four times as many lamps can be used on a single string as an incandescent string. The fluorescent lamps avoid safety problems in changing bulbs on the job. Furthermore, the plastic globe protects the workmen from the glass fluorescent tube, and there is no need for the cage that has to be used with incandescent lamps. If the string of lamps falls when it has been turned on, the lamps do not break or go out, and can just be re-strung in the workplace.
