ABSTRACT:
A portable fluorescent lamp fixture adapted for use with a plurality of fluorescent lamps includes an elongated center channel extending substantially the entire length of the fixture and disposed intermediate a pair of fluorescent lamps for providing a high strength, rugged structure. With a rubber end cap attached to each end of the center channel and a transparent protective tube comprised of polycarbonate or butyrate extending between the end caps and disposed about the center channel and fluorescent lamps, the lamp fixture is provided with a liquid-tight seal. The center channel includes an open lower portion along its length, having an inverted generally U-shaped cross-section, and is adapted to receive a removable snap-on cover along its entire length for enclosing lamp circuitry such as a ballast, a terminal block and wire leads. The removable cover facilitates access to lamp circuitry for maintenance. With a plug mounted to one end of the center channel and a receptacle mounted to its other end, the lamp fixture includes a quick connect/disconnect feature with power leads to other similar, serially coupled fluorescent lamp fixtures. Each end cap includes either a plug or receptacle integral with the end cap for mating with either a center channel receptacle or plug in a quick disconnect coupling arrangement. With the lamp end caps easily removed and all lamp circuitry disposed within the center channel with the removable cover, lamp maintenance is facilitated and lamp circuitry and wiring is protected during use.
