  • Patent number: 5436815
    Abstract: A portable fluorescent utility light makes advantageous use of one or more generally U-shaped fluorescent tubes by utilizing a transparent end cap or lens at the opposite end of the device from the electrical contact end. Thus, the present light may transmit light from the sides of the cylindrically shaped unit, and also from the end of the device. The relatively narrow end dimension, in comparison to the relatively long length of the cylinder, enables the device to be inserted into relatively small areas, in the manner of a conventional incandescent flashlight, but providing the additional benefit of light emission from the sides of the tube as well. Additional features may be provided, such as a refracting lens to focus the light emitted from the end of the tube, a variety of interchangeable temporary attachment devices, an internal reflector, and/or remotely locating the transformer or ballast and switch and sealing the unit to preclude explosive hazard from vapor ignition.
