  • Patent number: 7192160
    Abstract: A light for use in applications requiring conventional and specialized, dimmable lighting wherein the color of the emitted light can easily be switched. The light includes fluorescent and/or LED light sources which are dimmable by a control box. The control box further allows for switching between two light sources provided in the light. The light sources may provide white light or specialized light including red or blue “invisible” light required in some military applications or UV lighting.

  • Patent number: 6386736
    Abstract: A fluorescent work light having a cover with restraining elements for restricting the movement of the fluorescent lamp. The restraining elements are inwardly projecting integral portions of the cover and restrict the lateral, rotational and axial movement of the fluorescent lamp. The work light also includes a rotatable socket with permits the cover to be threadingly engaged to the handle while rotationally engaging the fluorescent lamp. The distal end of the cover may consist entirely of transparent material to thereby permit light to be emitted from the distal end of the cover in all outward directions. The handle is provided with a removable end cover which is interchangeable with a plurality of different end covers.
