  • Patent number: 4233655
    Abstract: A spotlight having a generally cylindrical housing with an integral radially extending pistol grip handle at one end, a cord retractor in the rear and a seal beam light closing the open end of the cylindrical housing. The lamp is held in a shock absorbing position by projections on the housing and an integral trigger connected to the housing through a living hinge actuates the switch to turn the light on and off. A trigger lock holds the light "on" and the trigger guard prevents the trigger from being turned on inadvertently. An improved cord holder is provided which utilizes a pinch connection.

  • Patent number: 4223861
    Abstract: A hanger for mounting elongated members relative to a wall surface which permits alignment of the elongated member in a direction perpendicular to the surface, and also in both directions along the surface. The uses of the hangers find particular application in hanging elongated fluorescent light troffers or mounting tubes, and for mounting other devices such as a lighted hand rail or an unlighted hand rail for stairways.

  • Patent number: 4218637
    Abstract: A combination floodlight, spotlight and flasher circuit is disclosed herein. The circuit is provided with a manual switch means, which will turn a spotlight to on, off, and flash, and turn the floodlight on, off, and to a battery saver position. The floodlight is operated through a unique inverter circuit and flasher circuit combination. Multiple combinations of switching modes make it possible to selectively accomplish various combinations of lights simultaneously.

  • Patent number: 4181928
    Abstract: A portable light having a U-shaped body and an elongated reflector supported on the body providing a space for batteries between the reflector and the body. Two lamps are supported on the reflector providing a flood light and a lens is supported on the body over the reflector and the lamps. Two cup-shaped end caps are supported on the ends of the light and one end cap has a frusto-conical shaped reflector integrally attached to it, and a lens closes the end of the cap having the reflector in it, and a lamp is supported on the reflector under the lens providing a spot light.

  • Patent number: 4023067
    Abstract: An inverter circuit suitable for use as a fluorescent lamp inverter ballast is disclosed. The inverter has the capability of starting the fluorescent lamp through regenerative feed-back techniques made possible by the amplification characteristic of the inverter switching transistor. Good efficiency at high frequency is provided by minimizing the transistor switching losses through use of resonant storage techniques and an unique feed-back system. Further, the normal energy lost in the feed-back circuit is eliminated by combining the resonant load means and the feed-back means into a single structure.
