  • Patent number: 5381322
    Abstract: A floodlight knuckle or pivot joint has a ballast incorporated into it, rather than into the housing or hood of the fixture that holds the reflector and lamp. Preferably, the ballast is incorporated into its own waterproof housing in the lower portion of a vertically oriented knuckle, below the bottom-most of the two flanges of the knuckle, i.e. so that the pivot flanges are disposed between the ballast-containing portion of the knuckle and the fixture hood. Alternatively, the ballast might be contained in the top channel of the knuckle (between the top flange and the fixture hood), or, perhaps, in an enlargement of one of the flanges.
